Why Blackjack Counting Calculator?

Exact EV (CDZ model)

Card Distribution Zone math: every action's EV is computed from the actual remaining shoe via Rust + WebAssembly. More precise than printed basic-strategy charts.

14+ Rule Variants

Vegas Strip, Macau, Atlantic City, Single Deck, Free Bet, Lightning, Power BJ, Always 6, and more. Switch presets instantly. Custom rules supported.

100% In-Browser

Computation runs entirely in your browser (Web Worker + multi-thread wasm). Hand and rule data is never sent to a server.

Web / iOS / Android

Same engine on all 3 platforms. Browser on the go, mobile app at home with session persistence (drift / IndexedDB).

Card Counting Helper

Shoe-tracking tracks remaining cards automatically. Instead of Hi-Lo / true count, EV is computed directly from the live distribution.

Free, No Ads

Web and core mobile features are free. Pro features (custom rules, etc.) available via mobile app subscription.

How it works (3 steps)

Pick the rule

Choose the rule preset matching your table (Vegas / Macau / Free Bet / etc.). Custom rules are supported.
