Betting on "Total Under" or "TU" implies that the final result of the selected event must not exceed the aforementioned value. Let's take the "TU 10.5" bet wagered for the number of games in the 1st set of a tennis match.

Another way to increase your chances of winning at the roulette table is to place mobile bets. It's also called a French bet, and for good reason  it can only be placed on one zero in a French or European wheel because the number of numbers on the wheel is different. This type is different from that of roulette.
