Coin Flip rules

Each flip is a fair 50/50 server result. A correct call multiplies the streak by 1.98; a wrong call ends the active round.

How a round works

  1. Place a wager.
  2. Call Heads or Tails.
  3. After a correct call, cash out or call the next flip.

Payouts and settlement

One correct call pays 1.98x when cashed out. Ten consecutive correct calls force a maximum cashout near 921x.

RTP, risk and strategy

Previous sides do not affect the next flip. RTP compounds downward over longer streaks.

RTP is measured over a very large number of wagers. A short session can finish far above or below it, and no strategy guarantees profit.

Fairness and verification

All ten sides are committed before the first call and revealed with the secret after settlement.
