Put loops on the board so that three rules are all true. That's the whole game.
Tap a square once for an X, twice for a loop, and a third time to clear it. An X is your note to yourself: "no loop here". The game can X out squares for you too: its X's are in a circle. Switch them on or off under the gear, in Automatic X's.
A region is the squares inside one thick border. Some boards ask for 2 loops in every region: a badge above the board says so.
A 1 beside a row means one loop goes in that row. A 2 means two, and a 0 means none.
Not side by side, and not corner to corner either.
Not every board is a square. Some have gaps in them. A gap is not part of the board, so no loop goes there. The dotted lines across a gap show which row or column a number counts.
Beat the clock! You finished at or under the target time.
Good timing: a little over the target time.
Slow and steady: well over the target time.
Hints and wrong loops add seconds to your time.
Stuck? Undo and Check are free. X hint and Loop hint show you the next step. Each one adds a few seconds to your time. If something turns red, Check becomes Help me: it shows what's wrong, for a few seconds too.
Every puzzle has exactly one answer.
