Overview

Blackjack Switch is one of many variations on the classic game of Blackjack and was invented by Geoff Hall. This game has come to be offered commonly both online and offline.

The primary difference between Blackjack Switch and classic Blackjack games is that the player has to play 2 hands and once the cards are dealt, the player can choose to switch the second card dealt to each hand around. The trade-off for this highly favourable rule is that Blackjack only pays 1 to 1 (rather than the standard 3 to 2) and if the dealer draws to a total of 22 this is considered to have ‘Pushed’ all hands other than Blackjack.

Optimal Strategy for Blackjack Switch comes in two parts; the decision whether to switch cards or not and the subsequent standard Blackjack Basic Strategy decisions.

For the switching decisions you should use our Blackjack Switch – Switching Decision Calculator.

If you are playing optimal strategy for both the switch and Basic Strategy decisions the House Edge for Blackjack Switch varies between 0.15% and 0.55% based on the specific rules you are playing against. The biggest difference is whether switched Blackjacks are counted as Blackjack or 21. If they’re counted as Blackjack you’re going to be playing far closer to the 0.15% figure.
