Paint Roller

Paint Roller is a clean, satisfying path-finding puzzle dressed up as a coloring game. Each level hands you a grid of blank tiles and a single roller, and your goal is to cover every tile with paint in one continuous, non-overlapping sweep. It looks simple, but finding the one route that hits every square without trapping yourself is a genuinely clever brain-teaser. The core challenge is spatial planning. Because you cannot roll back over painted tiles, every move narrows your options. Head into a dead end too soon and you will strand a corner you can no longer reach, forcing a restart. The best players learn to read the board like a maze, mentally tracing a path that flows through the whole grid before committing. There is a real "aha" moment when a tricky layout suddenly reveals its solution. Early grids are small and forgiving, perfect for learning the logic, while later levels introduce larger boards, blocked cells and irregular shapes that demand careful thought. The calm visuals and instant restarts make it stress-free to experiment, so you can puzzle away without penalty. For anyone who enjoys tidy one-line and Hamiltonian-path puzzles, Paint Roller delivers that pure, methodical satisfaction in a bright, approachable package.
