Fill It — Cozy Logic in Color Blocks

A warm, paper-textured logic puzzle. The only rule: fill the whole board with rectangles. Looks simple — gets addictive fast.

How to Play

Each dark circle on the board holds a number — that's how many cells its rectangle must contain. Your job is to divide the entire board into rectangles that don't overlap and leave nothing empty — one number per rectangle, the digit equal to the rectangle's cell count.

Sounds tricky. One puzzle in, and it clicks.

Three Challenges, Earn Them All

Every level has three independent badges to chase:

・Cleared — solve it within the time limit

・Speed — solve it with 60% time remaining

・Flawless — solve it without erasing a single block

The level select screen marks your progress with Bronze / Silver / Gold, so replaying old levels always has a target.
