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

The Maths in Naira

A European wheel has 37 pockets and returns 35 to 1 on a straight number, giving 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.

Put in naira, ₦10,000 wagered on a European wheel costs about ₦270. That same ₦10,000 on an American wheel expects to lose about ₦526. Same stakes, nearly double the cost.

Decoding the Tables

Euro in a name signals one zero. American means two. Roulette Boost, Bonus Roulette and Golden Time Roulette bolt on bonus layers, usually funded by changes elsewhere in the payouts. Common Draw 12 Numbers runs one spin for any number of players.

Staking systems like doubling after a loss do not beat the house edge. The edge applies to every spin on its own, so no pattern gets around it. Poker Roulette and Global Poker Roulette replace the numbers for playing cards, which changes the bets on offer. The single lesson from this tab, count the zeros before you bet.

Everything about the welcome bonus sits on the YOHAIG bonus page. Another guide is kept on the YOHAIG site.

Useful Figures

A single zero wheel has a 2.7 percent edge. A double zero wheel carries a 5.26 percent edge. Bet9ja serves more than 10 million users. Casino games make up 11 percent of Nigerian betting.

A Few Points

Roulette runs across four Bet9ja tabs. African Roulette is a Bet9ja exclusive, listed in three different tabs. 2 tables replace numbers with playing cards. Doubling up after losses does not beat the house edge, however long the run lasts.
