Trace is a free Android puzzle app that challenges you to link numbered cells in the correct order until every square of the grid is filled. The game focuses on pure logic, without timers, lives, or in‑app purchases, making it a quiet companion for anyone who enjoys a mental workout.
Each level presents a grid with a few numbers already placed. Your task is to draw a continuous line that visits every cell exactly once, starting at the lowest number and ending at the highest. The correct sequence fills the entire board, and the app automatically checks your solution. If a mistake is made, you can clear the board and try again.
Trace serves as a low‑stress way to keep your mind active. It can be used during short breaks, while commuting, or as a nightly routine to unwind. Because the game does not rely on external data, it is suitable for travel or situations where connectivity is limited.
The app is available through the standard Android package manager. After downloading, follow the usual installation prompts. No additional configuration is required to start playing.
