Casino Roll Lab

Educational craps simulator that teaches the mathematics behind every bet at the dice table using virtual chips only. No real money is involved or accepted at any point.

The interactive craps table simulator places the full game in your hand. Touch any bet zone to place a bet, then roll the dice and watch all wagers resolve. Each bet zone displays a built-in edge indicator — a colored stripe showing whether the bet has a low, medium, or high house edge — teaching optimal play through the interface itself.

The bet library covers more than forty wager types: line bets, Free Odds, place bets, buy and lay bets, hardways, the Field, Big 6 and Big 8, and all proposition bets. Each bet includes detailed rules, payout odds, probability breakdowns, and dice combination charts. The Free Odds bet is highlighted as the only true zero house edge bet in any casino.

The house edge ranking chart sorts every craps bet from best to worst, with bars colored green for smart bets and red for bets to avoid. The contrast between Free Odds at zero percent and Any 7 at sixteen point six seven percent illustrates the dramatic range of choices at a real table.

The Roll Lab runs batch simulations from one thousand to one million rolls instantly using any betting strategy. Live charts show bankroll over time and dice frequency distribution. The achieved house edge typically matches theoretical within fractions of a percent over a million rolls.

The strategy trainer features ten famous craps strategies including Pass Line plus Free Odds, the Iron Cross, 3-Point Molly, and the Hammerlock. Each strategy is explained with difficulty rating and a one-tap option to test it in the Roll Lab. Cautionary bad strategies are included as teaching examples.

The bankroll trainer answers a critical question: how long does a starting bankroll last at a given bet size and strategy? It runs one thousand simulated sessions and produces a distribution showing typical, lucky, and unlucky outcomes with key probabilities.

Lessons cover craps fundamentals, smart bet identification, probability deep dives, strategy mastery, bankroll management, etiquette and rules, and craps history including Patricia Demauro's record one hundred fifty-four roll session in 2009. Each lesson includes interactive elements and a quiz. Completing lessons earns Comps.

The myth debunker presents common craps beliefs that are mathematically wrong — hot shooters, cold tables, dice control, lucky numbers, and the gambler's fallacy. Each myth has a Prove It mini-simulation that demonstrates its failure with live math.

Two virtual currencies operate independently. Comps are earned through learning and simulation milestones and spent in the shop on permanent unlocks. The table bankroll is used for craps simulations and can be reset to ten thousand chips at any time with no penalty.
