A treble is a bet that involves three selections, all of which must win in order to be successful. A Trixie is also a bet that involves three selections, however it only requires two out of the three selections to come in and still returns a dividend. Trixie betting is considered a more cautious bet than a treble as it provides greater chances of success, but with lower returns. A treble also offers higher odds and bigger returns, however there is less chance of winning. It is important to consider the risk versus reward when deciding between a treble and Trixie bet.
