How it plays

Match free tiles

A tile is free when nothing lies on it and one side is open. Clear the board pair by pair. Hint, Shuffle, Swap and Peek help when you are stuck.

Collect cards

Match all four copies of a picture in a row and you collect its card. Many cards come with a fact and a short read about what is on the tile.

Explore new worlds

Every world brings a new one with it. Collect cards as you play and open the next world with the coins you earn.
