Betting systems choose your stake; playing strategies choose your action. Combine one of each in Simulation. These presets do not count cards or establish an advantage. Pros describe useful comparisons, not promises of profit.
Hand decisions · Known poor strategy
Hit below 17 and stand at 17 or higher, including soft 17. Never double, split or surrender.
Example: Stand on soft 17 even against dealer 10.
Easy comparison that isolates the cost of ignoring player options.
Player busts lose immediately, so copying the dealer does not create symmetry.

Simulator conventions: a unit is your base bet. Progressions use the complete round’s net result, including splits and insurance. They continue through cycles until the requested round count or an unaffordable bet. Opening bets are capped at the table limit. Martingale and D’Alembert update from the capped stake. Fibonacci stops advancing at the first sequence value reaching the cap, then moves back normally on profit; no hidden debt builds beyond the cap. Splits and doubles can add exposure. These adaptations differ from systems designed for even-money bets and fixed win goals.
Choosing a preset keeps your other settings and custom decisions. Custom decisions take priority; use Reset to basic strategy to clear them and restore the basic playing preset. Insurance is controlled separately. An unavailable custom action falls back to the selected playing preset.
Choose how to bet, build your own hand strategy, and see how a simulated bankroll changes over thousands of rounds. No account required.
Sampled at up to 502 round boundaries; peaks and troughs between samples may be omitted.

You can practise without an account. If you create one, we store your email address, display name and account dates. Password sign-in stores a salted password hash. Google sign-in uses your verified email, name and Google account identifier to connect your account.
A sign-in cookie keeps you logged in. Authentication and security records help us protect accounts and prevent abuse. If enabled for signup, Cloudflare Turnstile checks for automated traffic.
We record practice session identifiers, browser information, hands, cards, decisions, outcomes and aggregate statistics such as decision accuracy and simulated returns. These records support training feedback and progress. When you sign in, your practice session can be linked to your account.
