Puzzle Club

Tap to rotate. Tiles stay in place and cannot be dragged. Connect S to F, visiting the numbered circles—checkpoints—in order. Empty spaces and the endpoints marked fixed cannot rotate. Spare tiles can stay disconnected.

Use Tab and Enter or Space with a keyboard. Undo reverses a turn. Reset restarts this board. There is no timer or move limit. Difficulty labels are early estimates based on route choices, board size and checkpoints; more checkpoints alone do not always mean a harder puzzle.
