Tracer: One Line Puzzle

A new hand-tuned puzzle every level. Trace every line in one stroke: no lifting, no retracing. Now with dark mode, sound, and a level map you draw as you go.

Tracer is a one-stroke puzzle.

Each level is a figure of connected dots. Trace every line in one continuous stroke: no lifting your finger, no going over a line twice.

Simple to pick up. Deceptively tricky to finish.

WHY YOU'LL KEEP PLAYING

• Hand-made levels, tuned by feel and ordered from gentle to brutal
• A level map that draws itself: your progress is one continuous line
• Every connection plays a note, and solving a level lands the chord
• Lines ring like plucked strings, with haptics to match
• Dark mode that follows your phone
• Short sessions, no ads, no timers

THE RULE IS THE WHOLE GAME

If a figure has more than two dots where an odd number of lines meet, it cannot be traced in one stroke. Every Tracer level can be. Finding the path is on you.

Made by one person. More levels are always coming. If you enjoy it, a review genuinely helps.
