A house edge is the share of everything wagered that the operator keeps on average. Here is the formula, what it actually costs you, and the two numbers this site runs on.
House edge is the expected loss as a fraction of the amount staked: take every outcome, multiply each payout by its probability, add them up, and compare the total to what you put in. Written out, edge = 1 - (payout x probability of winning). A fair coin paying exactly 2x on a 50% chance gives 1 - (2 x 0.5) = 0, which is a game with no edge at all and no way for an operator to exist.
The wheel works the formula backwards. You choose what you want the multiplier to be, and the win chance is derived from it as chance = (100 x (1 - 0.10)) / multiplier. At 2x that is 45%, not 50%. At 10x it is 9%, not 10%. The 10% edge is the whole difference between the chance you get and the chance a zero-edge game would give, and because the formula is fixed, the edge is identical at every multiplier from 1.01x to 1000x. Nothing gets better or worse odds for being a longer shot.
Original is player against player, not player against house, so there is no edge in the wheel’s sense: the two of you are 50/50 with each other. What the site takes is a rake of 5% of the total pot, so the winner receives the pot minus that. On a matched wager, winning returns your own stake plus 95% of your opponent’s.
An edge is a long-run average, not a per-round tax you can feel. On the wheel, wagering repeatedly at any multiplier trends toward losing 10% of everything staked, and no bet size, multiplier or side changes that. Rakeback returns 5% of every bet you place, which reduces the cost of playing but does not remove it. The honest summary is that these games are entertainment with a known price, and if it stops being fun, that is the signal to stop rather than to chase.
The verifier recomputes a result in your browser from the seeds a settled round publishes. It never contacts our API, because a verification tool that asks the house for the answer verifies nothing.
The wheel carries a 10% edge at every multiplier. The Original coin flip is player versus player with a 5% rake taken from the pot rather than an edge against you.
No. The win chance is derived from the multiplier by a fixed formula, so the edge is the same 10% at 1.01x as it is at 1000x. Only the shape of the outcomes changes.
Yes, and it is arithmetic rather than trust: the win chance shown for any multiplier should equal 90 divided by that multiplier. An automated audit also re-derives every settled spin’s chance from its multiplier and reports any that disagree.
