The best payout in a European roulette game is 35/1 for a single number. However, the odds of hitting a single number are just 2.7%. The payout for an outside bet like Even/Odd is only 1/1 but the odds of hitting are much higher. For long-term profits, the outside bets are the best bet. You can try these bets the next time you play this roulette game online.
