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

What the Zero Costs

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 climbs to 5.26 percent.

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

What the Names Mean

Euro in a title signals one zero. American signals 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.

Betting systems such as 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 swap the numbers for playing cards, which changes the bet types on offer. The single lesson from this tab, check the zero count before placing a bet.

Background Numbers

A single zero wheel has a 2.7 percent house edge. A double zero wheel carries a 5.26 percent edge. Bet9ja has over 10 million accounts. Casino games make up 11 percent of Nigerian betting.

A Few Points

Roulette appears in four Bet9ja tabs. African Roulette counts as a Bet9ja exclusive, listed in three tabs. 2 tables replace numbers with playing cards. Doubling up after losses never beats the house edge, however long you keep going.
