Rarity calculator

See which hit results are rarest before a round starts. Kemeow ranks winner shares by hypergeometric rarity: higher "1 in X" means a rarer result. A 1 in 2 is a coin flip. A 1 in 4000 means if you played 4000 times, you will on average win about once.

Rarity order

Rank	Hits / picks	Rarity	Exact chance	Probability

Example: 4/10, 1 in 2.86 means hitting 4 numbers when you picked 10 has a 1-in-35,215 chance for that board and draw.
