Why Do Roulette Games Have Bet Maximums?

The strategy for playing casino games in which you have an advantage (there are very few of these betting situations on a casino floor, of course) is just the opposite.
In games where you have an advantage, such as a perfectly-played game of Blackjack, you have the edge on the house, and large bets are more advantageous for the casino. In a game where the player has the advantage, the casino’s best shot is to force you to make larger single bets, rather than to spread your bets out across the board. The best way to win in casino games with the advantage is to bet minimums.

Since most casino games give the house the great advantage, these games are vulnerable to enormous single bets. That’s where betting maximums come in, to protect the house where it is most vulnerable against one-time bets for big money amounts.
