Every flip is mulberry32(fnv1a(serverSeed:clientSeed:nonce)) < 0.5 → HEADS, else TAILS — a perfect 50/50 locked to a seed committed before you flipped. Each win pays ×1.98 (99 ÷ 50), and riding a streak just repeats the same fair flip with a fresh nonce, so RTP is exactly 99% at every depth.

? HOW TO PLAY
Pick HEADS (gold donut) or TAILS (emerald), set a bet and FLIP. Call it right and your pot becomes bet × 1.98 — then choose: CASH OUT or FLIP AGAIN to ride the streak. Every extra correct call multiplies the pot by 1.98 (×3.92, ×7.76, ×15.37 …) up to a 10-win streak (auto-cashout at ×919). One wrong call and the whole pot is gone. You can switch sides between streak flips.
Type bets like 2.5M, 250K or 500.000.000. AUTO flips single bets back-to-back with your side: roll count (0 = forever), on win / loss RESET the bet or raise it by a % (+100% on loss = martingale).
SPACE flip · C cash out · H / T pick side · M mute · 50/50 flips, ×1.98 per win, RTP exactly 99% at every streak depth.
