24 Puzzle

A classic 24-point game.

You need to use the four arithmetic operations of addition, subtraction, multiplication, and division to combine the randomly given 4 cards (value between 1 and 13). Each number must be used and can only be used once. If the final calculation result equals 24, you can score!

The thinking time for each question is limited, and you need to use your brain to solve the problem as soon as possible.

For each question you solve, a little bit of thinking time will be added.

As the game progresses, the difficulty will gradually increase.

At the beginning, only cards from A to 10 will appear, and later, cards from A to K will appear.

Let's see how long you can hold on!
