## What is TRACE?

TRACE - One Line Puzzle

Draw one continuous line through every open cell. No timer pressure, no ads, no accounts — just a clean daily puzzle.

HOW TO PLAY
Start at S. Drag or tap through adjacent open cells, filling each one exactly once, until you reach E. The puzzle solves itself the moment the last cell is filled — there's no submit button and no way to lose.

DAILY MODE
Three fresh puzzles every day — a 4×4, a 5×5, and a 6×6 — generated from the date, so every player gets the same set. Solve all three to keep your streak alive.

FLOW MODE
An endless run against the clock. Each solve adds time and raises your multiplier as the grids grow larger. Compare your best runs globally on Game Center.

WHY TRACE
• Fully offline — play anywhere, anytime
• No accounts, no ads, no tracking
• A new set of puzzles every day
• Clean, minimal design built around one simple rule

TRACE is a small, focused puzzle: one rule, one line, one path through the grid.
