This is a fun and relaxing mathematical game, in which you are given 4 integers (from 1 to 13), and you need to find a way to manipulate them using five arithmetic operations (addition(+), subtraction(-), multiplication (×), division(÷) and power(^)) as well as the parentheses so that the end result is 24.
For example, if you are given "1, 2, 3, 4", one solution would be :
"(1+2+3)×4".
Another solution would be :
"2^1*3*4".
Not hard, right?
There are 1339 solvable problems in this game.
The system will keep track of your problem-solving history, so that you know exactly which problems are unsolved/solved.
You are also free to pick any problem you want to solve/resolve.
The game interface is clean and intuitive.
Every task, such as moving numbers, changing operators, or adding/removing parentheses, is easily done by your fingers.
This is not a competitive game.
Just relax and take a few minutes playing it everyday.
I am sure it can keep your brain refreshed and active.
Try it and enjoy :)
