Tools & calculators

Run the real expected-value math on any draw.

For information and entertainment only — not financial, tax, investment, or legal advice. Every tool here produces estimates from published odds and simplified assumptions; they are not predictions. The lottery is a negative-expected-value bet. Consult a licensed professional before making any financial decision, and only play with money you can afford to lose.
