Poker 24 is an intellectual poker game. It tests one's mathematics skills and nimble thinking. J, Q, K cards may be excluded from the game. It may have 2 to 4 players. Let's take a look at the rule for 2 players. At the beginning, all cards are distributed to players evenly. To start, each player shows 2 cards from his/her stack, then calculate them as fast as possible to make 24 using any combination of "+ - x ÷ ( )" with the 4 numbers represented by the 4 cards. Whoever gets the answer fastest wins, and collects all 4 cards. If there is no solution, it's a tie, and each player get his/her 2 cards back. In the end, whoever collects all or more cards wins.
