New roulette players may be tempted to bet on a single number due to the 35:1 payout. If players bet a hundred and win on a selection with a 35:1 payout, then they can take 7,000 home. Who doesn’t want to go home with a lot of money? The problem is that the odds are 35/1, and higher odds mean that it’s harder to win.
The chances of hitting a single number you chose are low, making it difficult to win big with the bet. Splitting the bet between different numbers gives people a higher chance to hit the number, but it can be costly in the long run.
Combining a 2:1 and a 1:1 bet can lower the bettor’s losses since they’ll only truly lose money when the two bets are wrong. The gamblers can at least break even when they win one of their bets.
