WHAT IS HOUSE EDGE?
House edge is the built-in mathematical advantage a casino holds on every bet, expressed as a percentage of each wager the house keeps on average. It equals 100% minus RTP: a crash game with 99% RTP has a 1% house edge, costing $1 per $100 staked.
How house edge works
Every casino game pays winners slightly less than true odds would require, and that shortfall is the edge. It applies to each individual wager, so what really determines your expected cost is total turnover — every dollar you stake, including recycled winnings — multiplied by the edge.
Because edge is just the inverse of RTP, comparing games is simple arithmetic: 99% RTP = 1% edge, 96% RTP = 4% edge.
Why house edge matters for crypto players
Crypto casinos publish the edge of their provably fair originals right in the game rules — something slot studios rarely advertise. High-volume players feel the difference fastest: at $50,000 of monthly turnover, the gap between a 1% and a 4% game is $1,500 in expected losses. Rakeback then rebates a slice of that edge, effectively discounting it further for VIP grinders.
House edge at real crypto casinos
- Stake crash & dice — 1% edge (99% RTP), the benchmark for originals.
- Roobet crash — about 4% edge, among the highest for a crash game.
- Blackjack — 0.5-0.57% with perfect basic strategy, the lowest mainstream edge anywhere.
- BC.Game originals — around 1% edge on most in-house titles.
- Video slots — typically 3-6% (94-97% RTP), regardless of casino.
Common misconceptions
- "A low edge means I'll win." The edge guarantees the house's long-run margin, not your short-run result — variance dominates single sessions.
- "Betting systems beat the edge." Martingale and friends reshuffle when you lose, not whether you lose; expected value stays negative.
- "Edge is charged on my deposit." It applies per wager. A $100 deposit wagered ten times over faces the edge on $1,000 of turnover.
House edge FAQ
Which casino game has the lowest house edge?
Blackjack played with perfect basic strategy has a 0.5-0.57% edge, the lowest of any mainstream game. Among crypto originals, Stake's crash and dice run a 1% edge, while Roobet's crash runs about 4%.
Can you beat the house edge?
Not with bet sizing or staking systems — martingale and similar progressions change the distribution of results, not the expected value. Only rakeback, bonuses, or genuine player edges like card counting can offset it.
Is house edge the same as RTP?
They are two views of the same number: house edge equals 100% minus RTP. A 99% RTP game has a 1% house edge, and a 96% RTP slot has a 4% edge.
Why is house edge lower at crypto casinos?
In-house provably fair originals carry almost no licensing or studio costs, so operators can run them at a 1% edge and still profit on volume — roughly a quarter of the edge of a typical 96% RTP video slot.
