* Rotate and move the blocks to make squares with the same color.
* Remaining time will be added when going to the square or the next level.
* If you make squares at the same time, you will get a high score.
* Time is also related to scoring. Make squares as soon as possible to advance to the next level.
* If it is determined that the number of remaining blocks cannot make a square (3 blocks or less), proceed to the next level.
* There are up to 70 levels.
* If you tap the same block twice, it will rotate 45 degrees to the right.
* If you want to move a block, tap the destination block for the second time (position exchange).
* When the number of blocks becomes 3 or less, you advance to the next level.
