Frequently Asked Questions
What is Blackjack Switch?
Blackjack Switch is a variant where you play two hands and can switch the second cards between them. For example, if you're dealt A-5 and T-6, you can switch to get A-T (blackjack) and 5-6. The trade-off is that dealer 22 pushes and blackjack pays even money.
What is the house edge on Blackjack Switch?
With optimal strategy, Blackjack Switch has a house edge of about 0.58%. This is higher than basic blackjack despite the switching advantage, due to the dealer 22 push rule and even-money blackjacks.
When should I switch in Blackjack Switch?
Generally switch to: create blackjacks, create 20s or 21s, create two hands of 11 (for doubling), or improve two stiff hands (12-16). Don't switch if it would turn two good hands into bad ones.
Does the dealer 22 push rule matter much?
Yes, significantly. The dealer 22 push rule adds about 6% to the house edge, which is mostly (but not entirely) offset by the switching and even-money blackjack rules. This is why optimal switch strategy is crucial.

Results are verified against independent references (primarily Wizard of Odds). No calculation here is an opinion or recommendation; it is arithmetic applied to the rules of the game.
