Frequently Asked Questions

How does the keno odds calculator work?

The keno odds calculator uses combinatorial mathematics to assess the probability of catching selected numbers. It calculates odds by evaluating combinations of numbers drawn from a pool of 80, offering insights into expected returns and optimal strategies.
