Core gameplay
Each stage requires you to clear a specific row number (for example, row 5 from the top) instead of clearing rows arbitrarily. Blocks fill from the bottom upward. You must expose the target row by clearing rows above it.

Level and content structure
Fifty target-based puzzles. Each puzzle has a different target row between rows 2 and 12. Blocks can only be added at the bottom.

Visual and user experience
The target row is highlighted in amber. Cleared rows above the target disappear, dropping the target row closer. No other visual effects.

Features
A row counter shows how many rows remain above the target. Undo limited to three uses per puzzle.

User value
Changes row-clearing objective from quantity to precision. Encourages selective clearing strategies.

Usage scenario
Fifteen-minute breaks during household chores.
