The Swipe and Clear puzzle challenges you to play with colored square blocks that are stuck in stone mazes between gray slabs. To pick up blocks from there, you need to connect three blocks of the same color together. To do this, you will move blocks along free passages, achieving reunification. The levels are difficult, so first assess the situation, the location of the blocks and plan their movement6 so as not to end up in a dead end. Blocks cannot jump over each other and you cannot move two elements at the same time in Swipe and Clear.
