24Game Test your knowledge of mathematics

24 game is a mathematics game of ancient Japanese origins recreated in appinventor2 Blocks

GamePlay is fun and captivating with animations and sounds

The "24 Game" is a simple game. You are given four numbers between 11 and 99 (for example {1,3,4,2}) and your objective is to find an expression that evaluates to 24. The rules are fairly simple:

  • each given number must be used exactly once;
  • the only operations available are addition, subtraction, multiplication and division;
  • operations may be used repeatedly or not at all;
  • operation precedence can be manipulated by the use of parentheses;
  • no "clever tricks" should be used, only simple arithmetic.


If the given numbers are {1,3,4,2}, an answer could be

  • (1x3)x(4x2)

If the given numbers are {4,5,7,8}, an answer could be

  • 4+5+7+8

Hi, nice work. In your description you have multiple times used repeated values. That could be misleading for the readers on what to do. I guess you should edit your post.

Thanks for report It Peter.


The four numbers are randomly chosen from game engine in a range between 11 and 99

you mean 1 to 9?

In reality the game engine releases a string in a range between 1111 and 9999 avoiding the 0, which is then split into 4 single numbers

that's why you need to correct this:

It's reality a very big difference :rofl:
