Why you'll keep playing
Fill any row or column on the 9×9 board and it clears. Fill a row and a column together to clear both at once.
Clear several lines with one piece for Good, Great and Amazing combos, and a score bonus that keeps growing.

Stars appear on your blocks. Clear them to collect them. Ten stars fill the bar, level you up and pay you coins.
Stuck? Use a power tool.
Every level up pays you coins. Spend them on a tool and turn a hopeless board around.
Tap a block and it breaks, along with every block of the same colour joined to it. It usually takes out a whole shape in one go.
Fill any single empty cell. It's perfect when a row or column is just one block short.
Turn an offered piece a quarter turn so it fits. Pay once, and that piece keeps turning for free.
Drop a piece in the hold slot and save it for the perfect moment.
