Trace clean routes across a compact grid and close each loop without crossing blocked cells.
Each puzzle starts from a highlighted node. Connect adjacent cells, collect every beacon on the board, and return to the start to complete the loop. Different board sizes offer a simple ramp from easy routes to tighter layouts, while the hint overlay can reveal the underlying loop when you want a little guidance.
The app keeps the experience focused and local. Your progress, hint preference, difficulty choice, best times, and recent runs are stored on the device so you can continue later without an account or network connection.
Use reset and undo controls when you want to correct a route, switch difficulty for a fresh layout, or review past results. The interface is designed for quick sessions and clear feedback, with a compact board, success states, empty states, and lightweight local history.
