Can you bet one the same number in roulette as someone else?

Yes, you can bet on the same number in roulette as someone else. Roulette is a game of chance and each spin is independent of previous spins, so multiple players can bet on the same number without affecting each other's odds of winning.

In fact, in some casinos, it's possible to place a bet on someone else's number if they are unable to do so themselves. This is known as "betting behind" or "back betting", and it allows you to place a wager on someone else's chosen number or numbers.

However, it's important to keep in mind that in roulette, each bet is independent and has its own odds of winning. Betting on the same number as someone else does not increase your chances of winning, but it also does not decrease them.
