Bust or Bank

Bust or Bank does the math so you can focus on the game.

If you play a push-your-luck card game where the goal is to pull seven unique number cards without busting, you know the rules are simple — but tracking scores by hand gets in the way of the fun. Modifiers stack, halves round down, busts wipe the round, and someone always loses count. This app handles all of it instantly, so you can play more hands instead of doing arithmetic.

Why players love it:

• Tap-to-score interface — add a number, tap a modifier, tap Bank. The math happens in real time.
• Two rule-sets — Classic (additive modifiers, +2 through +10, ×2) and Vengeance (subtractive modifiers, −2 through −10, ÷2, plus a "lucky 13" special card).
• Auto-detects the seven-card bonus — pull seven unique numbers and the +15 applies automatically.
• Up to 10 players, with custom names and bright color tokens so you can see who's who at a glance.
• Set any target score — 100, 200, 500, your house rules.
• Round history is right there — see what everyone scored in each round.
• Big winner celebration when someone crosses the line.
• Works fully offline. No login. No accounts. No analytics. No ads. Your scores never leave your phone.

Perfect for game nights, road trips, holiday gatherings, lunch breaks. Anywhere you'd rather be playing the next hand than tallying the last one. Designed for one-handed phone use, so the person holding the app can still hold their cards.
