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
- Export your session as JSON or CSV to analyze with AI or in a spreadsheet
- 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, export the session data and keep it for your own records, or run it back through the simulator later to test a different strategy against the same set of rolls.
