This was a game my third grade math teacher used to play to get us to learn: a deck of cards, deal out four, and try to use the four basic operations of arithmetic to make the values of these cards turn out to be 24. Now I play it when there's nothing else to do and nobody around.

This online version is a little different, but not by much. It's my first game, took about twelve hours, wouldn't say it's perfect, looking for suggestions and improvements. Also, I am not a real coder, as can be seen by the opening GDevelop logo.

Instructions:

1. Click on the cards to flip them over. You have the option of not turning any of them over and keeping their values at zero.
2. Drag the numbers to the entry lines below. You can click on the operation symbol to get addition, subtraction, multiplication, or subtraction. Anytime you click on the two-way arrows (⇵), it takes you back to addition.
3. When you're ready, click on the equal sign to get an output. You can keep on using that output for further operations.
4. Use up all of the numbers and get a final output of 24 to score in the stack. Sometimes a solution is not possible, but try your best, move the numbers around, and think outside the box.
5. Click "Shuffle" to get new cards.
