DDrop blocks

It's a simple game where you move blocks and line them up by color.
1) Move blocks vertically or horizontally.
2) The game is cleared when the blocks line up in the order of white, black, red, blue, yellow, and green from the left.
3) If you can clear the target number of moves or less, the block will collapse.
You can change the difficulty level from the settings.

You can play even if you have a little free time.
To clear the game within the target number of moves, train your brain by predicting the placement of blocks after they are moved.
