A ‘Trio’ bet in roulette is an inside bet that is favoured by players who are willing to take on a bit more risk with the hope of landing a larger payout. Covering just three numbers of the roulette wheel, it offers an eye-catching payout of 11-1.

What is a Trio Bet in Roulette?

A Trio bet is one that sees a wager placed on three numbers at the same time. Specifically, this bet covers zero or zeros (depending on the version of roulette you are playing) and two other adjacent numbers. The Trio bet is similar, but different, to the Square bet.

In European Roulette, you could place a Trio bet on numbers 0, 1 and 2 or 0, 2 and 3.

In American Roulette, you could place a Trio bet on numbers 0, 1, and 2 or 00, 2 and 3.

The Trio bet adds something a bit different to your game of roulette, with substantial payout potential on offer. Offering a payout of 11-1, this sort of bet is ideal for players who are willing to embrace higher risk when placing their bets. As a Trio bet only covers three numbers on a roulette table, it can often be used as part of a broader roulette betting strategy.
