About These Tools

All probability calculations use the hypergeometric distribution, the mathematically correct model for keno. We compute results in log-space to handle the extremely large numbers involved (C(80,20) exceeds 3.5 quadrillion) without floating-point errors.

Paytable data is sourced from publicly available lottery and casino information. Always verify current paytables with your state lottery or casino before playing.
