Loto 7 number generator

How Loto 7 numbers work

Select seven different numbers from 1–37. Two Bonus Numbers are drawn by the operator for lower categories; neither is a separate number to choose.

This page is for Loto 7 (Japan). Main numbers are distinct and displayed in ascending order. There is no separately selected extra number in this generator.

The odds shown on this page

Match all 7 main numbers in one draw. Under a fair draw, the displayed chance for one complete line in one round is 1 in 10,295,472. This is the specified top-match category, not the chance of winning any prize.

C(37, 7) = 10,295,472

C(n, k) counts unordered selections of k distinct values from n. The science of chance explains why past results and visually balanced patterns do not improve a particular line’s chance.

Keeping the game in perspective

If the next draw feels difficult to leave alone, read about the urge to win losses back. For a conversation rather than more numbers, see support in Japan or choose where you actually live.
