Cohesion - The "sticky" puzzle
Cohesion is a "sticky" puzzle based on the classic "15 Puzzle", sometimes known as "slide the square", however Cohesion differs in one important way...
The squares in Cohesion are various colours. If two squares the same colour touch sides, they bond together. The bond is permanent, and the new shape it creates adds to the unique challenge of Cohesion.
The puzzle is solved when all the squares of each colour have combined.
