Dice Control Simulator: Testing Dice Influence Claims
Dice setting and dice control are among the most debated topics in craps. Can a skilled thrower influence the outcome? The Dice Control Simulator lets you test what would happen if dice influence were real.
- This is an educational tool exploring dice influence claims, not an endorsement
- Adjust the sevens-to-rolls ratio (SRR) and see how it changes every bet’s EV
- Even small reductions in 7-frequency can flip certain bets from negative to positive EV
- The required precision to achieve these shifts is extremely difficult (if possible at all)
How It Works
Set a custom SRR (sevens-to-rolls ratio). The default for random dice is 1:6, meaning one 7 appears every six rolls on average. Dice control advocates claim skilled throwers can push this to 1:7, 1:8, or higher.
The simulator recalculates the expected value of every craps bet at your adjusted SRR. You’ll see which bets flip from negative to positive EV and by how much.
What the Data Shows
At an SRR of 1:7 (a modest claimed improvement), place bets on 6 and 8 become slightly positive EV. At 1:8, most place bets turn profitable. The Iron Cross, typically a negative-EV strategy, starts looking attractive.
But here’s the catch: achieving even 1:7 consistently requires reducing the appearance of 7 from 16.67% to about 14.3%. Over thousands of rolls, maintaining that precision with bouncing dice on a felt surface is extraordinarily difficult.
This tool explores a theoretical “what if” scenario. The scientific evidence for dice control remains inconclusive. Casino dice are designed to be random, and most experts consider consistent dice influence impractical at best. Use this tool to understand the math, not to build a bankroll strategy.
Why This Matters Even If You’re Skeptical
Even if you don’t believe in dice control (and there are good reasons for skepticism), this simulator teaches something valuable. It shows you how sensitive bet EV is to small changes in dice probability. That understanding deepens your appreciation of why the best bets are the ones closest to even odds.

Dice Control Simulator FAQs
It’s debated. Some experienced players claim modest influence through specific grips and throws. Most casino professionals and mathematicians remain skeptical. The simulator shows the math of what would need to happen, and you can judge for yourself.
Most serious claims hover around 1:7 to 1:8. Anything above 1:9 would be extraordinary and would produce dramatic EV shifts across the board. The simulator lets you test any value.
