Fill and Number for Android

Quick overview

Fill and Number is a brain-teasing Android puzzle that pairs classic single-stroke drawing with an ordered-number challenge. The rules are easy to learn but the puzzles are designed to reward careful planning: you must trace every tile in one continuous path while visiting panels in a precise numerical sequence. Each level becomes an exercise in foresight and logical reasoning.

How the game plays

Players draw a continuous line that must pass through every panel on the board. Every move is constrained by the numbers on the panels, so the correct path requires predicting how later steps will interact with current choices. There are no timers or point tallies — the focus is purely on solving the arrangement through deduction and strategy.
