Roulette is the one Bet9ja casino tab where the table you pick really changes your odds. The tab holds 20 wheels, and they do not all carry the same edge.

The difference comes down to a single pocket. A European wheel has one zero. An American wheel has two, and that extra pocket nearly doubles the house edge.

One Zero or Two

A European wheel has 37 pockets and returns 35 to 1 on a straight number, leaving the house 2.7 percent. The American wheel puts in a double zero for 38 pockets, yet the payout stays at 35 to 1, so the edge rises to 5.26 percent.

In naira, ₦10,000 wagered on a European wheel expects to lose about ₦270. The same amount on an American wheel costs about ₦526. Same stakes, nearly double the price.

Reading the Labels

Euro in a name means one zero. American means two. Roulette Boost, Bonus Roulette and Golden Time Roulette add bonus layers, often paid for by changes elsewhere in the paytable. Common Draw 12 Numbers runs one spin for unlimited numbers of players.

Staking systems like doubling after a loss do not overcome the edge. The edge hits every spin on its own, so no pattern gets around it. Poker Roulette and Global Poker Roulette swap the numbers with playing cards, which changes the bet types on offer. If you take one thing from this tab, check the zero count before placing a bet.

The Stats

A single zero wheel has a 2.7 percent edge. A double zero wheel carries a 5.26 percent edge. Bet9ja has more than 10 million accounts. Casino games account for 11 percent of what Nigerians play.

Things Worth Knowing

Roulette runs across four Bet9ja tabs. African Roulette is a Bet9ja exclusive, found in three different tabs. Two tables swap numbers for playing cards. Doubling up after losses never beats the house edge, however long you keep going.
