The Power of Zero Edge

Zero house edge that we provide on the Duel website is a powerful force. But because the numbers involved are so small, it’s hard for people to intuitively comprehend just how serious the difference is.

Most games you’ll play will have a 3% house edge or maybe 2% or 1%. It doesn’t sound all that different, and you might think 0% is a step below that. But remember — the house edge is charged on every single bet. It’s a cumulative effect that becomes increasingly powerful the more you play, much like investing or compound interest.

In the long run, these small differences in house edge add up significantly. If you’re going to be playing at a casino for weeks, months, or even years, the choice you make here is going to result in a delta of hundreds of thousands of dollars even for small players, and tens of millions for whales.

The existence of any sort of house edge creates a tailwind — a drift — a necessary downward pressure. No matter how you play, the game will always ‘feel’ a little bit rigged, because the odds are mathematically stacked against you. When the house edge is zero, the odds of you winning or the casino winning are exactly even — so the results become pure randomness. Pure variance. There is no long term upwards or downwards pressure in either direction, creating some absolutely crazy long term results.

The most fun fact is this. A casino with a house edge and correct max limits is expected to make money in the long run. However, a casino with no house edge (regardless of limits) is always expected to go bankrupt in the long run!
