Explore house edge in the Casino Lab

Quantify why casino games are structurally negative for the player, and how staking interacts with a fixed edge.

Open the Casino Lab
  1. 1

    Read the bet table

    Each bet shows fair probability, payout, house edge, and player EV. Unlike the sports labs, casino EV is designed to be negative.

  2. 2

    Compare two edges

    Put a high-edge bet (single-number roulette) next to a low-edge one (even money) and compare drawdowns over the same number of rounds.

  3. 3

    Add a staking rule

    Run flat staking, then Martingale, on the same round sequence to see how progression interacts with house edge and a finite bankroll.

  4. 4

    See why size doesn't fix it

    Lowering stake size reduces dollar volatility but never removes the house edge — the expectation stays negative at every stake.

Key takeaways

  • Casino EV is negative by construction.
  • The extra zero on American roulette has a real cost.
  • Staking changes variance, not the edge.
