The Odds of Winning Lotto

The odds of winning a lotto is 1 in a million – 5 to 28 million depending on the type of game.

The table below shows the number of combinations you can make on each type of lotto game. For lotto 6/55, for example, the odds or chance of winning a jackpot is 1 : 28 million.

Lotto TypeNumber of Combinations

To get these results, use this formula:

c = n! / (n-r)! / r!


c = the number of combinations;
n = the highest lotto number in the game
r = how many numbers are drawn
! = the factorial of a number

For example, for lotto 6/42, n = 42 and r = 6. Using the formula: c = 42! / (42-6)! / 6!; i.e. the factorial of 42 divided by the factorial of 42 minus 6 divided by the factorial of 6. The factorial of a number is derived at by multiplying consecutive numbers. For example, the factorial of 6 or 6! is derived at by 6 x 5 x 4 x 3 x 2 x 1.

The Significance of These Numbers

The Philippine Lotto has drawn more than 3,975 5,310 jackpot numbers out of 56,364,337 million combinations. Can you imagine your chance of winning with one combination only? Therefore, to increase your chances of winning, play multiple combinations once or twice a month instead of playing 1 combination everyday. But if your budget is tight, playing 1 combination is not that bad idea. If you could only come up with the "perfect combination" or the combinations with high probabilities, maybe, your chances would be more positive. But how?

The LG+ or Lotto Generator Plus that can be downloaded from this page is a tool that calculates the probability of each lotto number or group of numbers.

Increasing the Odds of Winning

To increase the odds of being "lucky"  in a lotto game, you can eliminate the unlikely chances of winning. For example, the combination 1-2-3-4-5-6 is possible but very unlikely for the reason that a winning combination is usually a mix of numbers with no specific patterns. The lowest winning combination so far is 1-2-3-4-14-20. From 6/42 game, it is 2-5-6-7-8-10.

One by one, I'm going to explore the possibility of identifying which number combinations may be likely or unlikely to be drawn. So, do get back to this blog again and check out.

Good Luck and Good Fortune!
