Playing
- Pick black or white on the bar and type any amount you like.
- Your wallet signs one payment: the bet plus a 3% entry fee.
- The coin is flipped 50/50 as soon as the payment lands. A right side pays a straight 2x of your bet back to your wallet within seconds. A wrong side loses what you paid.
- There is nothing to claim and no round to wait for.
Odds and the fee
Both sides are equally likely, every time. Nothing about your bet, your history or the size of the amount changes that. The 3% entry fee is charged at the door instead of being deducted from a win, so a win is always exactly twice your bet.
Over many plays you lose about 3% of what you bet. That is the whole business model, and it is the reason to play small.
Randomness
The flip is one draw from a cryptographically secure random number generator on the server: a single bit, 0 for white and 1 for black. Run the same logic yourself below, as many times as you like.
Every flip is one draw from a cryptographically secure random number generator on the server. It produces a single bit: 0 is white, 1 is black. The odds are always 50/50, and neither your pick nor your amount changes them.
Try it, no wallet involved
Pick a side to run it.
No limits
- There is no maximum bet. The minimum is 0.001 SOL, only so the fee is not rounded away.
- On top of your bet and the 3% fee you pay the Solana network fee for your own transfer, roughly 0.000005 SOL.
Where the money sits
Payouts are automatic. If one cannot be sent immediately it is retried until it lands, so a delayed payout is not a cancelled one.
Risk
This is gambling. The expected value is negative, results are independent, and a streak means nothing about the next play. Never bet money you cannot afford to lose. The terms spell out the rest.
