The purpose of this game is to put operators in numbers and to make the calculation result the target value. Let's decide the number from 1 to 10 at random and use that value. There are four game modes. Aim for a high score!

Game
The target value is randomly determined from 1 to 10. Assign 1 to 10 randomly determined numbers to the 5 x 5 panel. Operators are randomly placed in 4 panels each. If the result is the target value, the numbers disappear and the score is added.

Game mode
・ Classic
It is a normal mode without any change. If you can not put numbers on the panel, the game is over. Perhaps this mode will be the longest continuous play mode.
・ Time attack
We will compete how many numbers can be erased in 120 seconds. Believe in your judgment and intuition and aim for a high score.
・ Move mode
Numbers can be placed up to 30 times. Erase multiple numbers at the same time and get high points with combo bonus.
・ Zen
Unlike other modes, it is possible to replace numbers. You can continue indefinitely.

Tutorial

Click the panel on the game to put the left most number of "Number:".
If you put a number, it will be left-justified and the new number will be decided randomly.

Place the numbers between operators.
If you set the number so that the calculation result is the value of * of "Just *", the two numbers disappear and the score increases.
It is also possible to erase multiple numbers at the same time.
