How to play Loopy

Loopy is a free daily single loop logic puzzle. Everyone gets the same grid each day: a square of dots, with numbers in some of the squares between them. Your job is to join the dots into one closed loop.

How the puzzle works

The loop runs along the grid lines from dot to dot, across or down, never diagonally. It's one single loop: it never crosses itself, never branches, and there are no loose ends or second loops. Each number tells you how many of the four sides of its square are part of the loop. A square without a number can have any number of loop sides, from none to three. Tap the gap between two dots to draw a line there, tap again to mark it with a cross (meaning the loop definitely doesn't go there), and a third time to clear it. You can also drag from dot to dot to draw several lines at once, or start a drag on a line to rub lines out. Numbers fade once they have the right count, and turn red if they have too many lines or too many crosses. A dot where three lines meet gets a red ring. When you think the loop is finished, press Check: Loopy tells you how many sides are wrong and how many are still to draw. Grids are 5×5 and easy from Monday to Thursday, and 6×6 and a step harder from Friday to Sunday. Every grid has exactly one answer, and you can reach it by logic alone, without guessing.

Scoring and the helper

Solve it on your first check and you earn 12 points; later checks earn 10, 8, 6, 4 and then 2. If your sixth check isn't right, the day is over. Pressing Check before you've drawn a line, or with nothing changed since your last check, never uses up a try. Stuck? The helper draws one side of the loop for you, but it halves the day's score and is only available until your third check.

Streaks and badges

Your play streak counts the days in a row you've played, and your solved streak counts the days in a row you've solved the puzzle. Play seven days running and you earn a 7-point bonus, or 14 points if you solved all seven. Miss a day and the streaks start again. A new puzzle arrives every day at midnight UTC.

Tips

Start with the zeros: cross off all four sides around a 0.

Every dot has either no lines or exactly two. A dot with one line and only one free way out must continue that way.

A 3 in a corner of the grid always has both of its outer sides on the loop.

Never close a small loop early: if one more line would close a loop while other lines are still loose, that side gets a cross.

What Loopy trains

Logical deduction. Using numbers to decide which edges are part of the loop.

Spatial reasoning. Keeping one single loop with no branches or crossings.

Patience. Corners and zeros give the first sure steps.

Did you know?

This puzzle is also known as Slitherlink, Fences or Loop the Loop.

Because it's one closed loop, every dot it passes through has exactly two lines meeting.
