European roulette: a wheel of 37 pockets — numbers 0–36 (a single zero). The numbers are colored red and black, and zero is green.
You place bets on numbers and zones, start the spin, and if the winning number lands on your bet — you receive a payout according to the table below.
1. Pick a chip denomination.
2. Tap numbers or zones on the table to place your bets.
3. "Double" doubles all bets on the table, "Repeat" re-places the bets from the previous round.
4. Press "Bet" and wait for the result.
5. The winning number lights up; on a win the payout is credited to your balance.
The multiplier is quoted "to one" (x:1). On a win you get your stake back plus the net profit:
Payout = bet × (multiplier + 1)
Example: a 100 bet on a single number (x35) that wins → 100 returned + 3500 profit = 3600 credited to your balance. Losing bets are forfeited.
The result of every spin is determined cryptographically: the server seed (its hash is published in advance) + your client seed + the round number (nonce) are run through HMAC-SHA256. After rotation the server seed is revealed — so you can verify that the results were never tampered with.
Balance and payout calculation are authoritative on the server. A bet is reserved before the spin, so two parallel spins against the same balance are impossible.
