Who will you be?
Your history is public. After a few rounds everyone can see what kind of player you are.
The Saint
Always splits. Earns the most marks when the table is kind, gets eaten when it isn't.
always split
The Shark
Always takes. Grows chips early, but nobody trusts a shark for long, and sharks earn no marks.
always take
The Mirror
Splits first, then does whatever was done to it last round. Simple and very hard to beat.
tit for tat
The Grudge
Splits until someone takes from it. After that, it never trusts anyone again.
grim trigger
In 1980 the political scientist Robert Axelrod ran a famous tournament of programs playing this exact game. The winner was the shortest one: split first, then copy your opponent. Even is that tournament with real players and real stakes. Run your own tournament in the strategy lab →
05 · Season & vault
Chips decide rounds. Marks decide the vault.
Taking grows your chips. Splitting earns marks. At the end of the season the ETH vault is shared by marks, not by chips.

Every $EVEN trade pays the creator fee straight into the vault contract.

- 01
Play every round. Only players who sealed a choice in all 12 rounds share the vault.
- 02
Stay in the bank. You can leave at any time 1:1, but leaving during the season gives up your vault share.
- 03
A take moves 3% of the smaller stack in the pair, so a whale can't swallow a small player in one round.
- 04
Both took? Each loses 2% of their chips into the pot, which is shared by every pair that split that round.
- 05
Your weight is the smaller of your chips at the seal and at the reveal, so moving chips mid-round doesn't help.

07 · FAQ
Fair questions.
Does sealing a choice cost gas?
No. A choice is a sealed commitment over your address, the round, your move and a random salt. It costs nothing and stays hidden until the reveal, when every move and salt is published so anyone can recount. Try recounting a round.
Can I talk to my stranger?
Yes, and you should. Pairs are public from the start of each round. Promises are not binding, which is the whole game.
Why can't a whale just farm small players?
A take moves 3% of the smaller stack in the pair, not of the bigger one. A whale taking from a small player wins little and gets a public shark history.
Is it audited?
No. The contracts will be published and verified before Season 01, but they are not audited. Play only with what you can afford to lose.
