BIG WIN

Rotating reveals the current server seed so you can verify every spin made with it, then starts a new hidden one.

1. Before you play, the game picks a random server seed and shows you only its SHA-256 hash, so it can't be changed later.

2. You choose a client seed. Each paid spin uses the next nonce (0, 1, 2…). Free spins in a bonus use the same nonce with round 1, 2, 3…

3. For each spin the game computes HMAC-SHA256(serverSeed, "clientSeed:nonce:round:cursor"), turns each 4 bytes into a number between 0 and 1, and uses 3 numbers per cell (cells left to right, top row first): the first decides whether the symbol stacks on the one above it (40% chance), the second picks a symbol from the published weights, and the third re-picks if a reel already has a Scroll (max 1 Scroll per reel).

Dice roll = floor(n × 10001) ÷ 100 · Coinflip heads if n < 0.5 · Wheel segment = floor(n × 10) · Plinko each row: n < 0.5 = left · Keno/Mines/Video Poker use a Fisher–Yates shuffle driven by the numbers · Duels first strike + each hit (0–25) from the numbers · Sports goals from each team's Poisson model.

Other games use the same seeds and nonce counter (round 0): Limbo/Crash result = floor(99 ÷ (1 − n)) ÷ 100 (1% house edge); Roulette number = floor(n × 37); Blackjack card i = floor(nᵢ × 52), dealt player, dealer, player, dealer (hole), then in order of play.

4. When you rotate seeds, the old server seed is revealed. Check its hash matches what you were shown, then re-create any spin in the Verify tab.

Sticky wilds from earlier free spins are placed on top of the generated board. Demo note: in this local demo the server seed lives in your browser. On a real site it would be kept on the server until revealed.
