Core gameplay
Blocks drop into a single column of eight cells. Your objective is to arrange blocks of matching colours in adjacent positions. When four identical colours touch, they disappear. New blocks continue falling until no further matches are possible.

Level and content structure
Thirty fixed puzzles. Each puzzle begins with a pre-filled column of blocks. You must clear all blocks within a limited number of drops.

Visual and user experience
The playing area is a narrow vertical strip. Colours are muted purple, green, and orange. All controls are placed directly below the column for thumb-friendly input.

Features
A restart button resets the current puzzle without penalty. No score display or timer appears during play.

User value
The single-column mechanic differs from traditional width-based puzzles. Suitable for short attention sessions where wide field scanning is not desired.

Usage scenario
Waiting for a kettle to boil or during short phone calls.
