THE OBJECTIVE
Think it through
Rotate the tiles to connect every endpoint into one network, with no loops or dangling connections.
YOUR CONTROLS
Make your move
Left-click rotates a tile one way; right-click rotates it the other way.
On a phone, use Touch: mark / reverse for a right-click action. Number puzzles include an on-screen number pad.
Choose an easier or harder grid in Type. Use Undo freely. Reveal solution shows the answer; it is a learning aid, not a hint. The timer starts on your first board interaction and stops automatically when you solve the puzzle. Use Finish practice to save an unfinished attempt. Complete 60 seconds of unrevealed practice with at least 3 board actions for the daily streak. Your last puzzle saves in this browser when device storage is available.
