Trace Once: One Line Puzzle

Trace Once is a relaxing one line drawing puzzle: draw every picture in one stroke, without lifting your finger and without going over a line twice. A brain game and logic puzzle with 300 levels, a daily puzzle and a timed Rush mode.

HOW IT PLAYS
• Press on the picture and drag along its lines
• Draw every line exactly once, in one stroke
• Went the wrong way? Drag back along the line to take it back
• Lift too early and the drawing resets: no lives, just try again
• Finish and the whole picture glows

HINTS THAT TEACH
• The first hint shows where you can start
• The second traces the whole path
• Start with 3 hints and earn another for every 4 new levels
