Play One Line Puzzle online for free at Game CMB. Connect every dot in one continuous line and solve hundreds of increasingly challenging puzzles, right in your browser — no download, no account required. Works great on iPhone, Android, tablet and desktop.
Touch or click a starting node and drag through the connected dots without lifting your finger or mouse button. Visit every required node to solve the puzzle. Once you've drawn a line between two dots, that connection is used up — you can't cross it again in either direction — so plan your route carefully before you commit to a path.
Look for dead-end nodes first and plan your route so you don't get trapped without unused edges leading out of them. It's fine to pass through the same dot twice as long as you use a different connection each time. Use the Hint button if you get stuck, and Reset to instantly start the level over.
