After the dealer releases the ball, whichever number it lands on is the winning number. 31bd offers European roulette and other variants, each with different payout ratios.

You can also interact with the dealer through the chat.
In baccarat you place a bet on one of three outcomes: "Player", "Banker", or "Tie". Both sides are dealt cards and the side whose total is closest to 9 wins. 10s and face cards count as zero.
