Loopy

About Loopy

Loopy is a compact logic puzzle about drawing a loop. The grid is mostly empty except for a few numbers. Each number counts down as your loop turns corners in the squares next to it (including diagonals and its own square), and you win when you have drawn one closed loop that brings every number to exactly zero.

Every day there are three puzzles: Easy, Tricky and Diabolical. They are generated from the calendar date and the difficulty, so everyone who plays on the same day gets the same grids. A timer runs while you solve, streaks are kept per difficulty, and an Unlimited mode offers random extra puzzles once the daily ones are done.

You draw by dragging across squares and tap to erase parts of the loop. Settings let you show all numbers or only the required ones, choose whether numbers count down or show the total, and add borders to the grid. The site is free, has no sign-up and is translated into several languages.

It suits fans of Masyu and Slitherlink who want something quicker, and newcomers who want a gentle loop puzzle with a tutorial.

How to play Loopy

1. Pick Easy, Tricky or Diabolical for today's puzzle.
2. Drag across squares to draw a path; tap to erase parts of it.
3. Watch the numbers: each one counts down when your loop bends in the squares around it.
4. Close the path into a single loop that brings every number to zero to solve the puzzle.

Tips

• A 0 or a small number in a corner restricts the bends nearby; use it to rule out squares early.
• Large numbers need many bends close together, which usually means a zigzag or a tight turn next to them.
• Turn on 'Show both' in the settings to see both the remaining count and the total.
• Do Easy first to learn how the counting works before trying Diabolical.
