A full table under simulation.
Seat computer players around you, put the dealer on a clock, and every card — yours and theirs — comes out of one accurately shuffled shoe. Casino rhythm, laboratory instrumentation.
Want a benchmark? The Daily Challenge deals everyone in the world the same simulated shoe — one attempt, one leaderboard.
Coaching that knows the exact play
Turn it on and every hit, stand, double, split, and surrender is graded against perfect strategy for your precise rules, with a plain-English why on each miss. Turn it off and just play.
Count like it counts
A Hi-Lo HUD with running and true count, between-hand quizzes, deviation practice with the Illustrious 18 and Fab 4, and a bet-spread ramp that responds to the count.
Simulate the whole career
The Bankroll Lab answers the only question that matters — is this game worth playing? — with EV per hour, risk of ruin, and hours to the long run for any bankroll and spread.
Pressure-test it in public
A Daily Challenge shoe dealt identically to everyone, and a weekly Ranked Challenge across famous casino rule sets. Simulation is practice; leaderboards are proof.
Blackjack simulation, answered.
What makes this a simulator rather than just a game?
Every rule a real pit enforces is modeled exactly — deck count, dealer soft-17 behavior, double-after-split, re-splits, surrender timing, peek or no-peek, penetration, and payouts — and the same engine computes the house edge and the mathematically best play for whatever table you build. Change a rule and every number updates.
Is it really free?
Yes — no ads, no chip packages, and never real money. The core simulator, every strategy chart, counting practice, and the daily and weekly challenges are all free, with no account needed.
Can it simulate card counting?
Fully. Turn on the Hi-Lo HUD to see the running and true count live, drill yourself with between-hand count quizzes, enable the Illustrious 18 and Fab 4 index deviations, and watch your bet spread's effect on EV.
Can it tell me if a game is beatable?
That's what the Bankroll Lab is for: enter any rule set, bankroll, and bet spread and it forecasts EV per hour, risk of ruin, and N0 — calibrated against more than 100 million simulated rounds — then tracks your real sessions against the forecast.
How fast can it deal?
As fast as you can decide. Deal speed is adjustable from casino pace to rapid-fire drilling, so you can compress an evening of table time into minutes of focused reps.
Does it run on my phone?
Yes — it's built mobile-first and runs in any modern browser with nothing to install. Add it to your home screen and it opens full-screen like an app, and it keeps working offline.
Stop guessing. Simulate it.
