How Roulette Bets Are Structured
A roulette table is split into two main betting zones: the inside and the outside. Inside bets sit on the numbered grid itself and cover one number or a small cluster. They pay more but land less often. Outside bets wrap the grid — red or black, odd or even, high or low — and land closer to half the time but
pay less. Beyond those two zones, European and French tables add a third layer called call bets and announced bets, which cover fixed sectors of the wheel rather than positions on the cloth. Knowing which zone a chip belongs to is the first thing that changes how you read the table.
