"The modern roulette layout comes from mid-nineteenth century France, making it one of the oldest casino games. Roulette dealers are often referred to as croupiers, which is the French word for dealer."

"The long run, so to speak, is the expected amount that you would win or lose if you played the game long enough to equal an average result. This is expressed as the EV, or expected value."

"The roulette wheel is always kept spinning at a constant rate, even if no one is currently playing. The ball is spun in the opposite direction in order to ensure more randomness in the result."

"Since nearly all bets in the casino carry an EV under zero, you can't only search for positive EV bets. Play the bets with the smallest casino edge and avoid the ones with the largest."
