Thunderball offers slightly better odds than the main Lotto jackpot.

The chance of matching all five numbers and the Thunderball to win the £500,000 top prize is 1 in 8,060,598.

As with Lotto, every number combination has the same chance of being drawn.

There are also several smaller prizes available, meaning you can still win money for matching fewer numbers, including just the Thunderball itself.

Remember to check your ticket carefully after the draw to see if you are a winner.
