Make 24 is a challenging math game in which you must create a formula with cards and arithmetic signs (+, -. /, *, and ()) which gives 24 as the result. There are certain cards, such as K, Q, A, and J, which have certain values that you must remember. However, what makes the game even more challenging, is that you have a limited amount of time (60 seconds) to create the formulas. If you don't manage to create a formula with the cards given in the allotted time, you will suffer the loss of points. If this is the case, you will be shown a possible answer and then other cards will be given and you'll have to create a new formula. When you have the formula, you must press the SUBMIT button, and if it is correct, you will be given points.
When the game is over, you will be shown your score and you will be able to publish it on multiple social sites to compete with your friends. The game has simple graphics and sounds, and suitable music.
In short, if you are looking for a very challenging game to test your math skills and mental speed, Make 24 may be a great choice.
