Core gameplay
Each block has a weight number (1 to 3). Heavier blocks fall faster. Your goal is to arrange blocks so that each row has equal total weight before clearing. A row clears only when the left and right halves have matching weight sums.

Level and content structure
Sixty puzzles with fixed weight sequences. No random generation. Puzzle solutions do not require speed.

Visual and user experience
Numbers are printed inside each block. The well uses a centre line to separate left and right halves. No moving background elements.

Features
A balance indicator shows whether the current row is closer to equal weights. Undo function available three times per puzzle.

User value
Adds arithmetic thinking to block placement. Suitable for users who enjoy calculation-based puzzles.

Usage scenario
Mid-afternoon breaks when mental energy remains moderate.
