[Purpose]
There are circles to which calculating formula is written.
Please drag it to the square to which the answer is written.

The square and circles disappear when the answer is correct.
It advances to the following stage when all squares are erased.

Let's advance the stage to lost of the time limit fast.


[Rule]
Under the screen, There are circles to which calculating formula is written.
Upper the screen, There are squares to which the answer of the expression is written.

Please drag circles to the square.
The square and circles disappear when the answer is correct.

The time limit decreases as a penalty for five seconds when a wrong answer is dragged.
The time limit is added for ten seconds when all squares are erased, and it advances to the following stage.

When the stage advances, the number of problems and the kind of the calculating formula change.
It becomes difficult.

It is a game end when the time limit is lost.

The number of stages that has been cleared up to now can be confirmed from RECORDS.
In RECORDS, the high rank is displayed tenthly.
