Which site did you play on?
Official, licensed casinos are regularly tested and audited, so the chance that the game is manipulated is very low. If you play perfect basic strategy, the house edge is usually around 0.5â1%, depending on the rules (European, U.S.âwhere the dealer checks for blackjack firstâor other variations). That built-in house edge is already enough for casinos to profit, so manipulating the games would be an unnecessary risk that could destroy their business if it were ever discovered.
If you feel like youâre losing too often, itâs usually just variance.
Youâd need a large sample size of
hands before you have any reliable basis for suspicion.
