FAIRYour SOL is held by the contract, not by the house
Bets and winnings are in SOL; the project has no token of its own. The game balance is recorded in an open smart contract: top-ups, payouts and withdrawals are executed by its code, with no requests and no operators.
What this means in practice
The balance cannot be taken or frozen
The contract has no command with which the administrator could take tokens from a player's game account or block it. Only your wallet's signature can withdraw the balance.
Top-up with one signature
SOL moves from your wallet to the game balance in one transaction. There is no project fee for a top-up.
Withdrawal with no requests
A withdrawal takes one signature: the contract transfers the SOL to your wallet right away. Nobody approves it and nobody can decline it. There is no project fee for a withdrawal.
Only the network fee
For a round the player pays the regular Solana network fee — about 0.00002 SOL. It goes to the network, not to the project. The house pays for the round's settlement.
Personal top-up address: straight from an exchange
The cashier shows your personal address on the Solana network. You can send SOL to it from an exchange or any other wallet — with no signature on the site. The transfer reaches your game balance automatically; this way you can start playing even with an empty wallet.
The address is derived from your wallet and belongs to the contract: nobody has a key to it, including the administrator. The only thing that can be done with it is to credit the SOL held on it to your own game balance. The minimum amount credited is 0.01 SOL. If your wallet is empty, a small part of the top-up will go to it so that there is enough for network fees.
The lock covers only the amount deposited
A top-up can be withdrawn after 12 hours. The lock applies only to the amount deposited: winnings and the rest of the balance can be withdrawn right away. This rule is written in the contract and is the same for everyone; the amount available to withdraw now is shown in the cashier.
A new top-up shifts the unlock time in proportion to its share of the locked amount rather than starting it over. So a small transfer from someone else to your top-up address does not delay your withdrawal.
Where the bet goes
The shares are written in the contract code and are the same for all players and all games: about 88% of every bet goes to the games' prize bank, 2% to the jackpot, the mini jackpot and the super jackpot, and the rest is the administrator's share. The detailed breakdown is on the “How it works” page.
The sizes of the prize bank and the pots shown on the site are numbers from the game's shared account in the contract; the same account can be opened in a Solana explorer.
What you should know
Blockchain transactions are irreversible: what is sent to the wrong address cannot be returned. The right to upgrade the program currently belongs to a single project key; every upgrade is visible to everyone in the explorer. Keep your wallet's secret phrase only with yourself: whoever knows it controls the wallet.
