HOW DOES HAVING DOUBLE ZERO ON THE ROULETTE WHEEL AFFECT THE HOUSE ADVANTAGE?

Unlike French and European Roulette with a single-zero wheel, American-style Roulette has a wheel with an extra sector with two zeros on it (the double-zero version of Roulette). While the European and French versions have a 2.7% house advantage, the American Roulette wheel has increased this advantage to 5.25% by adding an extra sector. However, Roulette with a double-zero wheel offers higher payout odds for some bets.
