The Fill

About The Fill

The Fill is a connect-the-block-style brain training puzzle game built around a single, elegant rule: fill every block using only one continuous line. The concept is immediately accessible, yet the puzzles grow demanding enough to keep your mind genuinely engaged. It's designed for downtime — a commute, the quiet before sleep — and the more puzzles you work through, the more active your thinking becomes.

Several scenes show paths colored green, red, orange, or purple running through the puzzle grids. A dotted white line runs through the center of every colored block, connecting them across the board. Small light-gray squares appear adjacent to colored paths in several configurations throughout the puzzles.

How to Play The Fill: Fill Every Block in One Go

The goal is straightforward: swipe or draw one continuous line that passes through every block without lifting your finger or mouse. Every block must be covered in a single unbroken stroke — backtracking is not allowed. Hints are free. As puzzles are completed, higher difficulty levels unlock, bringing more challenging arrangements to solve.

Controls

• Swipe / Draw (touch or mouse): Trace a continuous line through all blocks without lifting your finger or mouse
