The short answer is yes, but it makes no sense whatsoever to do so and that's because of the house edge. The highest paying roulette bet is on a single number, as it can trigger wins equal to 36 times the stakes.

Say a single-number bet has a 35:1 payout, and you betR$1. If you win, you'll get your money back plusR$35. Another example: If you win aR$100 bet (for a 35:1 payout), you get a total of $3,600 ($3,500 profit plus theR$100 you initially bet).
