What is house edge?

Simply put, the term ‘house edge’ refers to the casino’s mathematical and theoretical advantage over the player in any given game. It is calculated by purpose-built computer programs that simulate thousands upon millions of hands to determine how a game’s rules and betting options affect the probability of winning or losing and the expected returns over time when using proper strategy.

All casino games favour the house to some degree (with the exception of some older video poker machines), but the odds in 21 have always been far more player-friendly than most other forms of gambling. Even at land-based casinos in Australia, where operators are bending the rules ever further in their favour in a bid to protect their profit margins, blackjack and pontoon remain better bets than the majority of other table games.

For example, a standard Australian blackjack game might have a house edge of around 0.60 per cent. That means for every $100 you bet, you can expect to lose about 60 cents on average in the long run. By way of comparison, every wager in European roulette favours the casino by 2.70 per cent – an expected loss exactly 4.5 times greater. It’s even worse in American roulette, where the double-zero layout bumps the house advantage up to 5.26 per cent.

Basic strategy for online blackjack

There is absolutely no point scouring the web for the lowest house edge blackjack games if you don’t understand basic strategy. The computer simulations that calculate the probabilities and theoretical returns in 21 are all based on optimal strategic play, so any deviation from that renders the house edge irrelevant and greatly reduces a player’s chance of success.

Fear not, because blackjack strategy is much simpler than it appears at first glance. You don’t need to learn how to count cards – an entirely useless endeavour at secure online casinos – and a quick Google search will turn up a host of free blackjack charts and reliable strategy calculators. Not one strategy fits all, as the rules of blackjack are endlessly variable, so it is important to make sure you have the correct strategy chart for your game of choice.

Below is the basic strategy for Microgaming Classic Blackjack Gold. To figure out if you should hit, stand, split, double down, or surrender, find your initial hand or total points value on the left-hand menu and compare it against the dealer’s upcard. With these simple moves, the house edge comes to a mere 0.13 per cent – unmatchable value.
