Solitaire meets Blackjack. Try to create four stacks of cards equalling 21.
Four By 21: Solitaire meets Blackjack in this fast-paced single-player game. You are dealt one card at a time. Choose one of the four stacks to place the card. When the card values in a stack add up to exactly 21, that stack is cleared and you will score a point. If a stack value is over 21, that stack is busted. The game is over if you bust 5 times, or run out of time on the clock. Bonus points are given for consecutive stacks cleared. Brought to you by the makers of Pressed For Words!
