The Health Lottery odds calculator gives the exact chance of each result. You pick 5 numbers from 50, and the draw takes 6: five winning numbers plus a bonus ball. All five is 1 in 2,118,760 per line. The top prize is a fixed amount rather than a rolling jackpot, which is why the odds are so much shorter than the big national games. Use the free calculator above for any match and any number of tickets.
Health Lottery odds for every match
The bonus ball comes from the same drum as the main numbers. It helps a line that’s one short, so 4 + bonus is its own result.

How it compares
1 in 2.1 million for the top prize is about 10 times easier than the UK Lotto jackpot (1 in 22.5 million per two-round line), and around 4 times easier than Thunderball. You’re playing for a smaller fixed prize, and part of every ticket goes to health causes, which is the point of the game.
Play one line a day for a year and your chance of the top prize is about 1 in 5,800. The calculator’s “draws” box does that sum for whatever you play.
