A draw every half hour, decided by a public random beacon.
| Tier | Odds per ticket | Share of the pot |
|---|---|---|
| Jackpot | 1 in 10,000 | 80% |
| Major | 1 in 909 | 7% |
| Minor | 1 in 147 | 5% |
| Consolation | 1 in 45 | 3% |
A tier is split between everyone who hits it. A tier nobody hits pays nothing and keeps its share in the pot.
A round is open for thirty minutes. While it is open you can put tickets into it. When it closes, no more tickets go in and the round waits for the random number that decides it.
That number is a drand beacon — a random value published every three seconds by a public network of independent nodes. Each round names the exact beacon it will use when it opens, and that beacon does not exist yet while the round is still taking tickets. Nobody, including us, can enter a round already knowing how it ends.
Hold the token. While your balance is above the holder bar, holding time turns into free tickets at a rate that follows your balance: sitting exactly on the bar earns one ticket per round, ten times the bar earns ten. Nothing to claim daily and nothing to stake — it accrues by itself and you spend it whenever you like.
Or buy tickets outright, in any asset the arcade prices them in. Every unit you pay goes into the pot. There is no cut.
Bought tickets and free tickets are the same ticket once they are in a round. The only difference is what happens to unspent ones after a jackpot.
Each ticket is scored once, on its own, as `keccak256(randomness, round, your address, ticket index) mod 1,000,000`. Where that number lands decides the tier. Tickets do not compete with each other — two people can win the same tier in the same round, and they split it.
You can recompute every result yourself from the published beacon. Nothing about the draw is hidden or off chain.
After the draw you have a claim window — an hour by default — to claim your winning tickets. The arcade finds them for you; claiming is one transaction.
When the window closes the round settles and each tier is split between whoever claimed it. Then you collect.
Prizes nobody collects roll back into the pot after thirty days, so nothing is ever stranded.
A jackpot takes 80% of the pot and resets the game: every unspent free credit in the arcade is burned, and the next round starts from what is left. Credits you paid for are never burned.
At least 5% of the pot always survives a round, however many tiers hit, so the board never goes back to zero.
Drawing a round, settling it and opening the next one are open to anyone. There is no operator whose absence stops the game.
If a round's beacon never arrives, the round can be voided after a week and everyone takes their tickets back as credits a jackpot cannot burn.
None. The lottery takes no rake and no fee. Everything paid in — swap fees, ticket sales, donations — is in the pot, and the pot is only ever paid to players or carried forward to the next round.
A round can commit at most 95% of the pot, so at least 5% always carries. That is not a fee: it is the next round's starting balance.
