What does house edge mean?

House edge is the mathematical advantage the casino has over the player, expressed as a percentage. A 5% house edge means the casino expects to keep R5 for every R100 wagered over the long run.

Which casino game has the lowest house edge?

Blackjack with perfect basic strategy has a house edge as low as 0.5%. Baccarat banker bet (1.06%) and craps pass line (1.41%) are also excellent.

Does house edge guarantee I'll lose?

Not in the short term. House edge is a long-term statistical average. In any given session you can win or lose. But over thousands of bets, the math favours the casino.

How is RTP related to house edge?

RTP = 100% - House Edge. A slot with 96% RTP has a 4% house edge. Higher RTP means lower house edge means better odds for players.

Why House Edge Matters

Over 1,000 bets of R100 each (R100,000 total wagered), a 1% house edge costs you R1,000 on average, while a 5% edge costs R5,000. Choosing lower house edge games literally saves you money. This is why informed players favour blackjack and baccarat over slots and keno.
