Every L opens a new path.
18 courses of knight-move puzzles, plus a Daily course. Collect the stars with the knight’s L-shaped move: in order on the first courses, then in any order you like. You choose the route. The board grows from 5×5 to 7×7, with rocks and cracked squares you can land on only once. Each course’s shortest route is found by a computer search and sets the target for 3 stars; go over the move limit or get the knight stuck and you lose the course.
Knight’s Route is a route puzzle played with a chess knight; there’s no rival, just you against the board. Over 18 courses the board grows from 5×5 to 7×7, and the number of stars to collect rises from 3 to 7.
