The house edge is the average share of each bet the casino keeps over time. A 2% edge means about $2 lost per $100 wagered on average across many bets. It is why the casino profits overall even as players win constantly.
Why bonuses fight the edge
A welcome bonus, rakeback or cashback effectively returns some of the edge to you. They never flip a game positive long term, but they soften the margin - which is exactly why value-focused players hunt bonuses and play where rakeback is generous.
Edge by game
Blackjack (basic strategy): ~0.5%. Baccarat banker: ~1.06%. European roulette: 2.7%. Slots: 2-6%. American roulette: 5.26%. Some side bets: 10%+. Pick low-edge games and bonuses go further.
Stacking your advantages
Combine low-edge games, optimal strategy where it matters, a fair bonus and ongoing rakeback, then set a budget. You cannot beat the edge long term, but you can make it as small as the system allows.
