The House edge

According to statistic data, the rate of casino’s edge is about 8 %. It can be explained by the fact that the dealer is always the last one who checks his hand. If previous players bust, he takes their bets. Only after this he checks whether he bust or not. But part of the bets which were made at this table has been already taken by the casino. That is why the casino is always in advantage. But particular players, who act using different strategies, may reduce house edge to 0,5 %.

Some casinos introduce new rules to protest their edge rates. Of course, all of them are against players. Here is the list of rules which reduce player’s chances to win:

  • A large number of decks

  • Limits for doubling (e.g. you may double only 9s or only Aces)

  • Limits for re-splitting

  • Dealer hits soft 17

  • The hole card is played out when players have played their hands

  • 1:1 or 6:5 payment

  • Dealer wins pushes

  • Insurance option
