Practice every bet on the table before you risk real money. Pick what the dice show, throw them, and track exactly how each strategy would have played out — with nothing on the line but time.
What the Simulator Does
Most craps practice tools generate random rolls, which is fine for learning the flow of a round but useless for testing a specific scenario. The KnowYourCraps simulator works the opposite way: you choose the dice values yourself, roll after roll, so you can model a specific outcome, test how a strategy handles a cold streak, or replay your own logged results from a real session at the table.
It runs entirely in your browser — nothing to install, no account required, and no money ever touches it.
Features
- Every bet type: Pass, Come, Place, Buy, Lay, Hardways, Hop, Horn, Field, and the bonus bets
- Choose your own dice values to model specific rolls and sessions
- Standard and Crapless Craps modes
- Session tracking: P&L, roll history, and frequency stats as you go
- Customizable payouts to match any casino's specific table rules
How to Use It
Launch the simulator in a new browser tab, set your bankroll and table rules, and start placing bets. Instead of a random number generator deciding the roll, you pick the dice values yourself — which means you can deliberately run a hot streak, a cold streak, or replicate rolls you tracked during an actual session, and see exactly how a betting strategy would have paid out against them.
When you're done, the session stats give you a clear picture of how the strategy performed across every roll you entered — so you can compare approaches before you ever put real money on the table.
