21 Blitz

21 Blitz is a strategic card game which shares some of the rules of Black Jack. But unlike in the slow paced Black Jack the goal is to add up the cards to 21 as quickly as possible in the 4 available slots whilst having to complete 2 decks of cards. Think carefully about the cards you use and the cards you trash, before you know it you will find yourself running out of options. It seems like a simple task but can you think ahead and remember which cards have already been played?
