Ice Crack

How to play

1. Drag a block onto the board, or tap it and then tap the cell for its top-left corner.
2. A white-striped cell is ice. Blocks cannot land on it.
3. A full row or column clears ordinary cells and cracks the ice in that line.
4. Cracked ice clears the next time its line fills.
5. The round ends when nothing fits.

About

Place blocks on an 8×8 board that already holds ice. A full row or column clears ordinary cells and cracks the ice. Cracked ice leaves on the next clear.
