To solve Tumblestone puzzles, tap on 3 Tumblestones of matching color to remove them from the puzzle. After you select the first tumblestone in any set of three tumblestones, the color of the second and third stone will have to match the color of the first one.
The inhibitor puts lavalings into Tumblestone squares, so they cannot be selected for puzzle solving.
- Plan ahead at least one or two color sets
- Play in tutorial mode first to get a sense of the game
- If levels start to feel too difficult, play easier levels over again, as much as you want
