Sort the tiles by color to make them all happy! All the tiles of each color must be connected to each other. Click on a tile and drag to swap places with any tile next to it. When tiles of the same color are connected, they're happy!

Some levels will have tiles that are physically linked - indicated by a connector of the same color - and cannot be separated. When you try to move these linked tiles, they will move as a group. You also can't move them to a space that's too small for them. For example, if you move a group of three linked tiles into a space that can only fit two, they won't move into that space.

If you're stuck, click on the question mark button on the top right of your screen to get a hint on how to solve the level!
