Know Your Real Odds Before You Play
Powerball Probability Calculator is a free Windows desktop app that uses exact combinatorial mathematics to calculate every Powerball prize tier probability. No guessing, no approximations - the same formulas used by lottery commissions.

Complete Odds Dashboard - See jackpot odds (1 in 292,201,338), any-prize odds (1 in 24.87), expected value per ticket, and how many tickets you'd need for a 50% jackpot chance.
All 9 Prize Tiers - Full breakdown with match type, prize amount, exact odds, and number of favorable outcomes for every tier.

Built with .NET 8 WPF. Self-contained installer - no dependencies required.
- Add tickets by hand — type numbers from a ticket you already bought, or paste a whole multi-line ticket at once
- Paste works straight off the printed ticket, so line labels and the PB prefix are handled for you
- Edit any saved ticket to correct a number, then re-check it
- Matched numbers are now ringed in green so you can see exactly which balls hit
- Entry warns about out-of-range numbers, duplicate white balls, and dates with no drawing
- Saving generated picks now reminds you to check them against your printed ticket
- New My Tickets tab — save numbers from Smart Pick or Quick Pick and check them against official draws
- Running win/loss tracking with total spent, total won, and net result
- Power Play option applies the drawn multiplier when results are checked
- Expected value now accounts for the cash option, taxes, and the chance of splitting the jackpot
- Tax rates are adjustable, and default to Florida's zero state tax
- Draw history is cached locally, so the app works offline after the first refresh
- Full draw history now downloads instead of only the most recent 500 draws
- Calculator tab shows how fresh your data is and flags any draws missing from the source feed
- Smart Pick now respects the ruleset dropdown instead of always using current rules
- Fixed a crash when copying to the clipboard while another app was using it
