In blackjack, players attempt to reach a score of 21 without exceeding it before the dealer hits 17. You can win if you don't bust and your total is higher than the dealer cards. Hitting exactly 21 can mean even bigger winnings.

Counting to 21\n\n As in the previous game, players alternate saying one, two, or three numbers per turn. This time, the one who says "21" wins the game. What is the winning strategy now? Is it better to go first or second?
