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. Usually one loop each. When it's two, 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 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, for a few seconds on 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.
Tap each set to try it on the board below, and keep the one where the colours are easiest to tell apart. You can change it later under the gear.
