House Edge vs RTP
House edge and RTP are opposites. House edge = what casino keeps. RTP = what you get back. 5% house edge = 95% RTP. Lower house edge means better odds for you. RTP explained →
Long-Term Average
House edge is calculated over millions of bets. Short-term results vary due to luck. You can win sessions, even big wins, but over time the casino mathematically profits.
Why House Edge Matters
Lower edge means your bankroll lasts longer and you have better chance to win. Choosing games with 0.5% edge vs 5% edge dramatically affects your expected results.
Can You Beat the House Edge?
In the long run, no — the math always favors the casino. But you can win sessions, use bonuses to offset edge, and make smart game choices to minimize losses. Bonus guide →
