An avid gambler or someone who is just curious about the game of roulette might be wondering what the expectation is for $1 bets on a US roulette wheel. The answer to this question depends on a few factors, such as the number of bet options available on the roulette wheel, how often those bet options are used, and whether or not the casino offers any bonuses for making $1 bets.
Generally speaking, casinos offer lower odds for making $1 bets than they do for making larger wagers. This means that a player who wants to place a $1 bet has a better chance of winning $2 or less on the roulette wheel than he does of winning more than $2.
However, there are some rare instances where a casino will offer slightly better odds for making $1 bets than for making larger wagers. So, overall, it is safe to say that the expectation for making $1 bets on a US roulette wheel is somewhere between 50 and 100 percent chance of winning.
