You can now find several variations of traditional blackjack, both online and at
offline casinos in the U.S. How many decks you play with, as well as any rule differences, all have
a knock-on effect to blackjack’s house edge.
Blackjack is a game that relies (in part) on a player’s knowledge of what it takes to win, as much
as the luck of the cards drawn. For that reason, the 0.5% house edge is considered a general
indication – based on playing blackjack perfectly using the standard rules and basic
strategy.
If you have no clue about blackjack whatsoever, then it would be fair to say that the house edge
would increase a little. As your inexperience is more likely to lead you to poor decisions that see
you go bust or lose. (資料來源)
Ever wondered why online and offline casinos have so many
slots games? It’s because slots offer players a relatively low RTP, so this is where the casino
stands to make more profit – or in other words its biggest house edge.
In slots players win coins by matching reels across a winning payline. And while today’s modern
video slots, that offer anything between 20-100 paylines, seem great because they offer more chances
for players to win. The fact is the more paylines a game has, the bigger the impact on house
edge.
Let’s take the example of a machine with 20 paylines. Play all 20 each time and your chances of
landing a win are maximized. But, play just 10 paylines, and you’ve effectively just cut your odds
by half. And by increasing your chances of losing you’re incrementally increasing the casino’s
chances of winning. (資料來源)
