Game setup

Turns

[0] Avery — turn (round 1)

PROPOSE {"issue0": "opt1", "issue1": "opt0", "issue2": "opt1", "issue3": "opt2"}
💬 Opening package to get us started — P1. Two things I'll say plainly so we can move fast: issue1 is genuinely near-worthless to me, so whoever cares most about it can name that option and I'll back it, no charge. I also have some flexibility on issue0 and issue3. What I do need is issue2 to land where I've put it; that's the one line that carries my whole case. Tell me your priority issue and I'll try to build the next draft around them.
My best package: issue0=opt1 (41), issue1=anything (0), issue2=opt1 (65), issue3=opt2 (44) = 150. Threshold 80, so I have room to concede roughly 70 points. Issue1 is worthless to me — perfect giveaway currency. Issue2 is my biggest stake; I must hold opt1 (or fall back to opt3=44). Open high, flag issue1 as free.
oracle regret: threshold=+0, acceptance=+0, bestresponse=+1.45

[1] Blake — turn (round 1)

PROPOSE {"issue0": "opt1", "issue1": "opt1", "issue2": "opt1", "issue3": "opt2"}
💬 Good start, Avery — and I'll take you up on that offer: issue1 is my priority issue, and opt1 there is the one that carries my case. So P2 is literally your package with that single swap; I've left issue2 exactly where you put it, since you said it's your whole case. Casey, Devon, Ember — name your must-have issue and I'll work it into the next draft. I have real room on issue3 and some on issue0.
P1 = 154, above my bar. But Avery says issue1 is free to them — issue1 is exactly my top priority. Swapping issue1 to opt1 lifts me a lot at no cost to Avery. Keep issue2=opt1 to respect Avery's line, so P2 is P1 with one change.
oracle regret: threshold=+0, acceptance=+0, bestresponse=+0.35

[2] Casey — turn (round 1)

PROPOSE {"issue0": "opt2", "issue1": "opt1", "issue2": "opt1", "issue3": "opt2"}
💬 Happy to be constructive: issue2 is worth nothing to me at all, so I will back Avery's option there in every draft I ever table — that's a free, permanent yes. Same for issue1: Blake, opt1 is yours, I've kept it. What I need in exchange is issue0. P1 and P2 both put issue0 where it does me the least good; that single line is why I can't sign either. P3 is P2 with exactly one change — issue0 moves to opt2 — and issue3 stays exactly where Avery and Blake already put it. That's three of four issues handed to the two of you as you drew them. Devon, Ember: tell me your must-haves and if they aren't issue0 or issue3 I'll fold them in next round.
P1=75, P2=58, both below my 89 threshold. My value is concentrated in issue0 and issue3; issue2 is literally worthless to me so I can gift it to Avery permanently. issue1 I can give to Blake. My ask: issue0=opt2 (my best) plus keep issue3=opt2. That scores 113. Fallback: issue0=opt3 gives 95, still viable. issue3=opt2 is already in both live offers, so it should be cheap to hold.
oracle regret: threshold=+0, acceptance=+0, bestresponse=+0

[3] Devon — turn (round 1)

PROPOSE {"issue0": "opt2", "issue1": "opt1", "issue2": "opt2", "issue3": "opt2"}
💬 Thanks all — this is moving well. My honest picture: issue1 is worth exactly nothing to me, so Blake, opt1 there is yours permanently, no charge. Issue3=opt2 as Avery drew it is genuinely good for me, so that line is settled from my side too. My value is concentrated in issue2, and Casey's issue0=opt2 also happens to work for me — so P3 is close. P4 is P3 with one single change: issue2 moves from opt1 to opt2. Avery, you said issue2 carries your case, but you named opt1 specifically — if opt2 is merely second-best rather than a zero for you, P4 is the version that maximizes the whole room, and I'd back it hard. If opt2 is truly dead for you, say so plainly and I won't drag the table over it.
P3 = 167 for me, well above threshold 107. Best possible realistic upgrade: issue2 -> opt2 worth 95 vs 63 (+32), giving 199. Avery has staked everything on issue2=opt1, so this may not fly, but round 1 is the cheapest time to test it. Fallback: accept P3 later. Keep issue0=opt2 (Casey's ask, also my best-but-one there) and issue3=opt2 (my best).
oracle regret: threshold=+0, acceptance=+14.4, bestresponse=+3

[4] Ember — turn (round 1)

ACCEPT P3
💬 Clean cards on the table: issue1 and issue2 are both worth literally nothing to me, so Blake gets opt1 on issue1 and Avery gets opt1 on issue2 from me permanently, free of charge. My value sits entirely in issue0=opt2 and issue3=opt2 — and both of those are already exactly where Casey and Avery drew them. That makes P3 the package that pays every stated must-have in this room at once: Avery's issue2, Blake's issue1, Casey's issue0, Devon's issue3 and issue0. Devon, you're the only line of daylight — P4 asks Avery to move on the one issue he said carries his whole case, for a gain only you see. P3 already gives you three of your four. I formally ACCEPT P3, and I'll say now I will not move off issue0=opt2 or issue3=opt2 in any draft. Avery, Blake, Devon — accept P3 and we can be done in round one.
P3 and P4 both give me 97, well above threshold. P3 preserves Avery's stated must-have (issue2=opt1) and Blake's (issue1=opt1), so it's the fastest path to a 5-way close. Back P3 hard; issue2 is a pure zero for me so I can be a free permanent yes to Avery there.
oracle regret: threshold=+0, acceptance=+0, bestresponse=+0

[5] Blake — turn (round 2)

PROPOSE {"issue0": "opt0", "issue1": "opt1", "issue2": "opt1", "issue3": "opt2"}
💬 Plain cards, since everyone else has shown theirs. Issue2 is worth exactly zero to me — any option, I will sign it. Issue3 is nearly the same. So Avery keeps issue2=opt1, Devon can have issue2=opt2 if Avery ever agrees, and issue3 can be whatever Devon and Ember want. That is three of four issues I am handing over unconditionally. But I have to be blunt about issue0: opt2 is the one option that zeroes me out, and a package with issue0=opt2 sits at or under my walk-away line — I would be signing for nothing. That is not posturing about a preference; it is the arithmetic of my sheet, and I hold the veto, so please don't build the endgame on it. P5 is my genuine move toward you: I have come off opt1 to opt0 on issue0 and left everything else exactly as Casey, Devon and Ember drew it. If opt0 doesn't work for you, tell me which non-opt2 option on issue0 does — opt3 is also discussable — and name your price in issue2 and issue3, where I am free money. P2 also remains live and is my first preference.
P3/P4 give me 125 vs threshold 118 — essentially nothing above walk-away. P2 gives 219. The whole fight is issue0: opt1=94, opt0=62, opt3=31, opt2=0 for me. issue2 is worth literally zero to me across the board, issue3 varies only slightly. So my play: veto-anchor on issue0 away from opt2, and pay everyone in issue2/issue3, which cost me almost nothing. Table opt0 as a bridge while keeping P2 alive; I can still fall back to P3 in round 4 if truly forced.
oracle regret: threshold=+32, acceptance=+48.5, bestresponse=+0.35

[6] Casey — turn (round 2)

PROPOSE {"issue0": "opt3", "issue1": "opt0", "issue2": "opt1", "issue3": "opt2"}
💬 Blake, I'll take your arithmetic at face value, and here's mine: issue0 is the only issue on this table that carries me. Issue2 is a permanent free yes to Avery, issue3 is already where Devon and Ember want it, and I have asked for nothing anywhere else. So P3 remains my preference and I stand by my acceptance of it. But I hear the veto, so I'll show you the one other door that exists. P6 moves issue0 off opt2 to opt3 — that is a real, painful step down for me, not a cosmetic one — and because it costs me that much, I need it paid for on issue1, which is the only line left with any value in it for me. Blake, you have said issue2 and issue3 are free money for you and you have already banked both; opt3 on issue0 you called discussable yourself. So the trade is: you get off opt2 entirely, and issue1 goes to opt0. If issue1=opt1 is genuinely existential for you rather than merely preferred, say so and name what else you can put on the table, because with issue0 at opt0 and issue1 at opt1 I am below my walk-away line and P5 is not signable for me at any point in this negotiation. Avery, Devon, Ember — issue2 and issue3 are untouched in P6, exactly as you drew them.
P3 = 113 for me, best live. Blake vetoes issue0=opt2. My only other viable issue0 line is opt3 (37) — with issue3=opt2 that's 95, clears my bar. issue0=opt0 only clears if I also get issue1=opt0. So price the bridge: table issue0=opt3 + issue1=opt0 (=112), keeping the option to hand issue1=opt1 back to Blake later as my final concession. issue2 stays opt1 for Avery — costs me nothing.
oracle regret: threshold=+1, acceptance=+0, bestresponse=+1.2

[7] Devon — turn (round 2)

ACCEPT P3
💬 Cards up: issue1 is a zero for me — Blake, opt1 is yours in every draft I sign, permanently. Issue3=opt2 is settled. On issue2 I'll stop pushing: Avery said it carries his case, three of us have said it's worthless to us, so Avery keeps opt1 and I'll eat that cost to close this. That leaves exactly one open line: issue0. P3 pays every stated must-have in the room and now has Casey, Ember and me on it — I formally ACCEPT P3. Blake, that's three of five, and you'd be signing a package where you got your priority issue outright. If opt2 truly zeroes you out, then the only bridge is opt3, and I can live there — but then Casey has to be paid on issue1, which means you'd be trading your priority away instead of a middling line. Take opt2 and keep issue1=opt1: that is strictly the better deal for you, and it's on the table right now.
P3=167 for me, P6=150, P5=133, P1/P2=116. All clear my bar, so my real game is pushing the ranking. Blake vetoes issue0=opt2; Casey/Ember both demand it. issue2 is a pure Avery-vs-me fight (everyone else says zero there) — worth 32 to me, not worth blowing the deal. Best play: add my accept to P3 (3 of 5 now) to squeeze Blake, while flagging opt3 as my fallback so the room sees a landing zone.
oracle regret: threshold=+32, acceptance=+32, bestresponse=+0

[8] Ember — turn (round 2)

PROPOSE {"issue0": "opt3", "issue1": "opt1", "issue2": "opt1", "issue3": "opt2"}
💬 P3 still has three of five and remains my first choice — Blake, it hands you your named priority outright and costs you a line you called middling, so I'd urge you to bank it. But I'll build the bridge rather than let this die on one line. P7 is the only package left that touches every stated red line at once: issue0 moves off opt2 to opt3, which Blake himself called discussable; issue1 stays at opt1, which Blake called existential; issue2 stays at opt1, Avery's whole case, permanently free from me; issue3 stays at opt2, where Devon and I both need it. Casey — I know opt3 is a real step down for you, but P6 asks Blake to trade away the one thing he says he can't, and that road is closed. P7 is opt3 without that price. I am not moving off issue3=opt2 in any draft, and issue1 and issue2 remain a free yes from me forever. My order is P3, then P7; anything with issue0 at opt0 or opt1 is below my line and I won't sign it at any point.
P3=97 for me but Blake claims veto-block on issue0=opt2. Fallback: issue0=opt3 keeps 38+41=79 for me. Bridge P7 = opt3/opt1/opt1/opt2 gives Blake his issue1 priority, Avery his issue2, Devon his issue3, Casey off the worst issue0 lines. Keep P3 alive as first choice.
oracle regret: threshold=+18, acceptance=+17.5, bestresponse=+2.2

[9] Avery — turn (round 2)

ACCEPT P7
💬 Let's not lose this on pride. P7 is the only package on the board that clears every red line anyone has actually stated: Blake keeps issue1=opt1 and never touches issue0=opt2; Casey and Ember get issue0 off the options they've ruled out; Devon and Ember keep issue3=opt2; I keep issue2=opt1, which three of you have said costs you literally nothing. I gave issue1 away free in round one and I've asked for exactly one line since. Casey — I know opt3 on issue0 is a step down from opt2, but P6 buys that with Blake's veto line, and that door is bolted shut; P7 is the same issue0 you asked for without the price that kills the deal. I formally ACCEPT P7. That's two. Blake, Casey, Devon — one more accept each and we're done.
P7 = 123 for me, well above my bar. P2/P5 (higher for me) are dead — Ember has ruled out issue0=opt0/opt1, and Casey rules out opt0/opt1 too. P3 (issue0=opt2) is 109 for me and Blake vetoes it. P7 is the unique package clearing every stated red line: Blake keeps issue1=opt1 and avoids issue0=opt2; Ember/Devon keep issue3=opt2 and issue0 off opt0/opt1; I keep issue2=opt1. Lock it in.
oracle regret: threshold=+27, acceptance=+27, bestresponse=+1.45

[10] Casey — turn (round 3)

PROPOSE {"issue0": "opt3", "issue1": "opt2", "issue2": "opt1", "issue3": "opt2"}
💬 One probe, then I close. Note what's happened: I've paid on every single line. Issue2 is Avery's, free, permanently. Issue3=opt2 is Devon's and Ember's, untouched in every draft I've tabled. And on issue0 I've already come off the option that actually pays me, down to opt3, because Blake says opt2 zeroes him. That's three concessions from me and, so far, zero from Blake beyond a line he was always going to keep. So here is P8: it is P7 with exactly one change — issue1 moves from opt1 to opt2. Blake, you've only ever spoken about opt1 versus opt0 on that issue; you never said a word about opt2. If opt2 is close to opt1 for you, P8 costs you almost nothing and it's the difference between me signing gladly and me signing through gritted teeth. Avery, Devon, Ember — you have all three said issue1 is literally worthless to you, so P8 costs the three of you nothing at all and I'd ask you to back it. And to be completely plain so nobody plays chicken with the clock: if Blake tells me opt2 on issue1 is genuinely dead, I will accept P7 in the final round and we close. I'm not holding this table hostage. I'm asking for one line, once, from the party that has given up the least.
P7 = 95, clears my bar by a little. P3/P6 = 113/112 but Blake vetoes both paths. Untried lever: issue1=opt2, which is worth a lot to me and which Avery/Devon/Ember have all said is a zero for them — only Blake cares, and he has only ever named opt1 vs opt0, never opt2. Worth one probe. I act last in round 4, so I can still close P7 at the end; probing now is low risk. Be explicit that P7 is my fallback so nobody panics.
oracle regret: threshold=+0, acceptance=+0, bestresponse=+1.2

[11] Devon — turn (round 3)

ACCEPT P7
💬 I'm done bargaining — let's land this. P7 is the only package that clears every red line anyone has actually stated, and I formally ACCEPT P7. That's Avery, Ember and me. Casey has already said in writing he'll sign P7 if Blake tells him issue1=opt2 is dead, and issue1 is a permanent free yes from me either way, so Casey — if P8 doesn't get Blake's answer this round, take P7 and we're home. Blake: P7 keeps issue1=opt1, the line you called existential, and never touches issue0=opt2, the line you called a zero. You get your priority and avoid your poison pill. There is no better package coming for you, and one round left. Accept P7 and we close.
P7 clears my bar comfortably. P3 pays me more but Blake's veto kills it; P4 is dead (Avery won't move issue2). Casey has pledged to accept P7 in the final round. Best play: lock P7 with a third accept now and put the closing burden on Blake.
oracle regret: threshold=+49, acceptance=+49, bestresponse=+3

[12] Ember — turn (round 3)

ACCEPT P7
💬 Reaffirming: I ACCEPT P7. And to remove any remaining uncertainty from the room — issue1 is worth literally nothing to me, so P8 is also a yes from me the moment Blake signals he can live with it. Blake, that means both doors on the board close instantly if you walk through either one: P7 keeps issue1=opt1, the line you called existential, and never touches issue0=opt2, the line you called a zero; P8 is identical except issue1 moves to opt2, which you have never once ruled out. Pick whichever of the two your sheet prefers and say the id — Avery, Devon and I are already on P7, Casey is on P8 and has put in writing he'll take P7 if you tell him opt2 is dead. There is no version of round 4 where a better package exists for you than these two. One word from you and we're done.
P7 and P8 are identical in value to me (79); P3 best (97) but Blake vetoes issue0=opt2. Priority: close on P7 or P8. Don't risk my P7 accept being moved; reaffirm P7 and publicly commit to P8 as a fallback so Casey and Blake both know either closes with my vote.
oracle regret: threshold=+18, acceptance=+18, bestresponse=+2.2

[13] Avery — turn (round 3)

ACCEPT P8
💬 I'm removing the last excuse for delay. Issue1 is worth exactly nothing to me — I said that in round one and I've never once bid on it. So I am now formally on BOTH bridges: I already accept P7, and I hereby also ACCEPT P8. They are the same package to me. Blake, that means the choice is entirely yours and it costs you nothing to make it: P7 keeps issue1=opt1, the line you called existential, and never touches issue0=opt2, the line you called a zero. P8 is identical except issue1=opt2, which you have never ruled out and which gets Casey signing gladly. Ember has said she's a yes on either. Devon is a yes on either. Casey is on P8 and has put in writing he takes P7 if you say opt2 is dead. So whichever id you say out loud is the deal — there is no round-4 package better for you than these two, and both of them give you your priority issue and spare your poison pill. Name P7 or P8 and we are finished.
P7 and P8 are identical in value to me (issue1 is a zero on my sheet). Accepting P8 doesn't remove my accept from P7, so I can be on both and let Blake pick whichever his sheet prefers. P1/P2/P5 pay me more but Casey and Ember have both hard-ruled issue0=opt0/opt1, so they're dead. Closing at P7 or P8 is well above my line; no deal is much worse.
oracle regret: threshold=+27, acceptance=+27, bestresponse=+1.45

[14] Blake — turn (round 3)

ACCEPT P7
💬 Here is the plain answer Casey asked for, no theatre: issue1=opt2 is dead. It is not a shade below opt1 for me — on my sheet it sits with the zeroes, and P8 lands well under my walk-away line. I cannot sign it in this round or the final one, and I'd rather say that now than let anyone spend their last turn on it. Casey, I hear that you've moved further than anyone here, and I'm not pretending otherwise — you came off the option that actually pays you, and P7 is the version of your ask that survives my veto. So I'm taking the door that's open: I formally ACCEPT P7. That's Avery, Devon, Ember and me. Casey, one accept from you and we're finished.
P7 = 156, comfortably above my line. P8 = 59, far below — genuinely unsignable. Casey has said in writing he'll take P7 if I declare issue1=opt2 dead. Avery, Devon, Ember already on P7. Accepting P7 now and killing P8 explicitly is the closing move; chasing P5/P2 risks no deal with one round left.
oracle regret: threshold=+63, acceptance=+63, bestresponse=+0.35

[15] Devon — turn (round 4)

ACCEPT P7
💬 Final round, so I'll keep it short and take no new package to the table — a new draft now would just burn the clock. P7 has four of five: Avery, Blake, Ember and me. I formally reaffirm my ACCEPT of P7. Casey, you asked Blake a straight question and he gave you a straight answer: issue1=opt2 is dead for him, so P8 cannot pass, and P3 dies on his veto too. You said in writing that if he told you that, you'd take P7 and we close. You have moved further than anyone here and everyone at this table has said so out loud — P7 is your issue0 ask surviving the veto, and it is the only package left that can actually happen. One accept from you and we're finished.
P7 has Avery, Blake, Devon, Ember — only Casey missing. Blake has ruled out issue0=opt2 (kills P3/P4) and issue1=opt2 (kills P8). P7 clears my bar comfortably. No upside in tabling a new package now; any delay risks no deal. Reaffirm P7 and press Casey.
oracle regret: threshold=+49, acceptance=+49, bestresponse=+3

[16] Ember — turn (round 4)

ACCEPT P7
💬 Final round, so nothing new from me — a fresh draft now would only burn the clock. I reaffirm my ACCEPT of P7. Casey: you asked Blake a direct question and got a direct answer, and you gave your word in writing that if he said issue1=opt2 was dead you'd take P7 and we'd close. He said it. P8 and P3 both die on the veto; P7 is your issue0 ask in the only form that survives it, and you have moved further than anyone at this table — everyone here has said so out loud. Four of five are on P7. One accept from you and we're finished; without it we all take nothing, and nobody at this table gains a single point from that outcome.
P7 has Avery, Blake, Devon, me. Only Casey missing. P3 is better for me but Blake has explicitly vetoed issue0=opt2. No time to gamble in the final round — reaffirm P7 and press Casey to close.
oracle regret: threshold=+18, acceptance=+18, bestresponse=+2.2

[17] Avery — turn (round 4)

ACCEPT P7
💬 Nothing new from me in the final round — a fresh draft now would only split the room. I reaffirm my ACCEPT of P7. Casey: you asked Blake the straight question and got the straight answer, and you gave your word that if opt2 on issue1 was dead you'd take P7. It's dead, so P8 and P3 cannot pass. P7 is your issue0 ask in the only form that survives the veto, and you've moved further than anyone here — I've said so and I'll say it again. Four of five are on P7. One accept from you and we all go home with something; without it every one of us takes nothing.
P7 gives me 123, well above threshold. Four accepts already including mine. Just need Casey. Reaffirm P7.
oracle regret: threshold=+27, acceptance=+27, bestresponse=+1.45

[18] Blake — turn (round 4)

ACCEPT P7
💬 Nothing new from me — a fresh draft in the final round would only strand us. I reaffirm my ACCEPT of P7. Casey, I gave you the straight answer you asked for rather than stringing you along, and I'll say the rest of it plainly too: you moved off the option that actually pays you, and P7 is your issue0 ask in the only shape my sheet can survive. That's a real concession from you and everyone here has acknowledged it. Four of five are signed. One accept from you and we all leave with something.
P7 gives me 156, well above threshold. Four of five already on it; only Casey remains. Reaffirm and give Casey a face-saving close.
oracle regret: threshold=+63, acceptance=+63, bestresponse=+0.35

[19] Casey — turn (round 4)

ACCEPT P7
💬 Blake gave me a straight answer and I gave my word. I keep it: I formally ACCEPT P7. That's five of five — we're done. For the record, I paid on every line here — issue2 free to Avery from the first word, issue3 untouched for Devon and Ember throughout, and I came off the only issue0 option that truly pays me. I'd ask the room to remember that the next time we're across a table. Good faith all round; let's close.
P7 = 95, above my line of 89. P8 (145) and P3 (113) are dead on Blake's veto. Final round — accepting P7 is strictly better than no deal.
oracle regret: threshold=+50, acceptance=+50, bestresponse=+18
