One Line Grid

One Line Grid is a minimalist logic puzzle about finding one continuous route through the whole board. Start at dot 1, visit every numbered dot in order, cover each open cell exactly once, and never cross a wall. Choose Easy, Medium, or Hard and solve a fresh procedurally generated board with a proven unique solution. Retrace the path to erase a mistake, use a hint when stuck, and track personal best and average solve times for every difficulty.
