The Wheel and How It Works
Roulette centres on a spinning wheel divided into numbered pockets and a corresponding betting layout. A ball released into the spinning wheel settles in one pocket, determining winners across dozens of possible wagers. Online versions use certified random number generators for RNG tables, while live streams broadcast physical wheels operated by trained croupiers.
European wheels contain 37 pockets — numbers 1 through 36 plus a single zero. American wheels add a double-zero pocket, increasing the house edge on most bets. Irish-facing lobbies overwhelmingly default to European or French variants, making American tables easy to avoid when seeking better long-term odds.
The house edge on a European even-money bet is 2.7% — among the most transparent margins in the casino, with every outcome visible on the wheel itself.
Inside and Outside Bets
Inside bets target specific numbers or small groups: straight-up on a single number pays 35:1, splits cover two adjacent numbers at 17:1, and corners capture four-number squares at 8:1. These wagers hit less frequently but deliver larger returns when successful.
Outside bets span broader categories — red or black, odd or even, high or low, and the three dozens or columns. Payouts sit at even money or 2:1, with hit rates high enough to sustain longer sessions on a fixed bankroll. Most beginner-friendly strategies anchor on outside bets combined with strict loss limits.
French Rules and Live Variants
French roulette applies la partage or en prison on even-money wagers when zero hits. La partage returns half your stake; en prison leaves the bet locked for the next spin. Both rules cut the effective house edge on those bets roughly in half compared with standard European tables.
Live auto-roulette blends physical wheel authenticity with automated ball release, streaming 24/7 without dealer breaks. Speed roulette variants shorten betting windows for players who prefer rapid-fire rounds. Immersive and multi-camera tables add cinematic angles without changing underlying mathematics.
Bankroll Approach for Online Sessions
Divide your session budget into units representing 1% to 2% of the total — a €200 session might use €2 to €4 base units on outside bets. Avoid progressive staking systems that double wagers after losses; they cannot overcome the built-in house margin and accelerate ruin during cold streaks. Set a win goal and stop-loss before the first spin, then honour both regardless of momentum.
