Duel Expected Value Calculator
Calculate the expected value of any Duel game configuration — with and without rakeback. Enter any house edge and rakeback rate to understand your true mathematical edge.
Quick Answer
What is expected value in Duel games?
Expected value (EV) is the average financial outcome of gambling over many repetitions. In casino games, EV is negative — the house retains a mathematical edge. Rakeback reduces this negative EV by returning part of the house's margin. The calculator below computes EV for any combination of house edge and rakeback rate.

EV Reference: Duel Games
| Game | House Edge | Rakeback | EV / $100 | Effective Edge |
|---|---|---|---|---|
| Blackjack (Basic Strategy)Best EV | 0.5% | 5% | -$0.475 | 0.475% |
| Crash / Dice / Plinko | 1.0% | 5% | -$0.950 | 0.950% |
| Roulette (single zero) | 1.0% | 5% | -$0.950 | 0.950% |
| Mines / High Variance | 1.0% | 5% | -$0.950 | 0.950% |
| High-RTP Slots (97%) | 3.0% | 50% | -$1.500 | 1.500% |
| Average Slots (96%) | 4.0% | 50% | -$2.000 | 2.000% |
All figures assume DUEL5 rakeback tier. EV = Expected Value per $100 wagered after rakeback.
