SquareBlockPuzzle is a dropped puzzle.
Let's make the square in the block of the same color.
The block is gradually pushed.
When the line is exceeded, it is an end.
Let's drop fast by using the previous notice block on the right side and erase the block.
It rotates for touch, it grips, it moves, and the block can be dropped when separating.
A white block that comes out uncommonly is a special block.
All blocks where the same color is connected are erased.
Let's effectively use it.
