About this game

Turn a simple loop into the right shape. Trace Flow: One Line Puzzle is a compact pattern puzzle game where you drag an elastic line around grid points to recreate a target design. Look at the small reference pattern, plan each pull, and reshape the loop on the board.
HOW TO PLAY
- Study the target pattern above the board.
- Drag a section of the line toward a grid point to change its shape.
- Adjust the loop until its pattern matches the reference.
- Use undo or reset to try another approach, and ask for a hint when needed.
RESHAPE THE PATTERN
A small change can transform the whole loop. Think about corners, straight sections, and the points between them as you work toward the target shape. The controls are direct: choose a line section, pull it, and see the pattern change.
170 CLASSIC CHALLENGES
Play 170 classic levels with distinct target patterns. Replay completed stages to revisit their shapes, and keep your progress saved locally between sessions.
PLAY AT YOUR PACE
Use hints, undo a move, or restart the board when you want a fresh attempt. Adjust sound and music in the settings to suit your session.
If you enjoy shape matching, spatial puzzles, and simple touch controls, explore the patterns in Trace Flow: One Line Puzzle. Pull the loop, find the shape, and complete the next pattern.
