Small habits that make a big difference.
Leave room for big pieces. A board full of small gaps is how runs end.
In Timer mode, look at the numbers. Build lines around the pieces that are about to turn to stone.
A single blast can free a whole cluster of stone. Do not spend it on one block.
Fill a line with one color on purpose. Mixed rows are blocked rows.
Clearing several lines in one move scores more, and three or more at once earns a free hammer.
The multiplier is powerful, but one stone resets your momentum. Stay calm and keep the board clean.
All themes play the same. Choose the one you enjoy looking at.
