One line. Every tile.
Trail is a generated one-line logic puzzle: draw a single line from a starting ring through every tile on the grid, and the level grows a little harder each time you advance. It plays free in the browser and as a free App Store app with full screen, offline play, and haptic feedback.
Drag or swipe anywhere to draw a single line from the ring through every tile on the board.
Drawing back over the line only undoes at a dead end — anywhere else you tap.
Levels are generated rather than hand-authored, and each level gets a little harder than the last.
A levels screen lets you pick which level to play, and any level can be restarted.
A built-in 12-step guide explains how the line mechanic works.
The iOS app offers the same levels as the web version in full screen, offline, with haptic feedback.
Start at the ring and drag or swipe anywhere to draw one continuous line across the board.
The goal is to pass the line through every tile on the grid without splitting into multiple strokes.
If you hit a dead end, drawing back over the line undoes your moves; elsewhere on the line, tapping is how you interact.
Completing a level advances you to the next one, which is generated to be a little harder than the last.
Trail is free on both the web and the App Store.
