Why catching zero pays
- You pick halfYour selection is 12 of 24. The other half of the board is left unpicked.
- Half is drawnLoto-Québec draws 12 of 24 with an electronic ball machine based on a random number generator.
- Zero is the mirrorIf none of your numbers is drawn, every drawn number is one you left out. Your ticket was the exact opposite set.
- Same odds both waysMissing all happens in as many ways as catching all, so both have odds of 1 in 2,704,156. More in why zero pays.
