How Live Roulette Works

A live table is a physical wheel in a studio, filmed and streamed, with your bets placed on a screen. The odds are the odds of the wheel. What the technology changes is timing: when you can bet, how long the result takes to reach you, and how many spins fit in an hour.

1. From wheel to screen

One round, as a pipeline. Times are typical, not guaranteed; they vary by studio and by your connection.

2. The betting window and latency

Because the video reaches you a few seconds after it happens, the betting window closes on the server before the ball slows noticeably. “No more bets” on your screen is the server’s clock, not the dealer’s hand. The gap protects the game from anyone with a faster feed; it also means that a bet confirmed on your screen is the only bet that counts.

Key factStream delay does not change the odds. The result is fixed by the wheel the moment the ball drops; what you see is a replay a second or two old.

3. How the result is read

Two readings are taken. The dealer announces and marks the number; a camera-based recognition system reads the pocket from the wheel image (or from a sensor in the rim) and the two must agree before bets are settled. Disagreements pause the table, which is why a round occasionally stalls for a few seconds after the ball lands.

Game-show variants add multipliers on some straight-up numbers and pay less on the others; their house edge is higher than 2.70% and is covered separately.
