These 25 games run entirely in your browser with no signup, no download, and no real money. They exist to teach the math. Every table game here uses the same rules and payouts you will see in a licensed online or land-based casino, so any hand you practice transfers directly to the real thing. Blackjack, video poker, and Ultimate Hold'em each carry a basic-strategy coach that flags suboptimal plays in real time — the fastest way to internalize the correct move in every situation. Slots, craps, roulette, baccarat, and sic bo show the underlying probabilities so you can see exactly how the house edge compounds over time. Keno is included on purpose: at a 25%+ house edge it is the worst bet in the casino, and the numbers make that case better than any warning label.
The house edge badge on each card is the specific percentage for that game under its standard rule set. Lower is better for the player. Blackjack at 0.43% is the best bet in the casino if you play perfect basic strategy; the same game at 6:5 payouts or hit-soft-17 rules jumps past 2%. Video poker 9/6 Jacks or Better is a 99.54% return with optimal holds; an 8/5 machine is 97.3%. The rules matter more than the brand. Practice here, then read the strategy writeup on each game page before you ever put real money on the table.
