About this game

One loop. Every number satisfied. That's the whole game.

Loop the Loop is Slitherlink — the classic Japanese pencil puzzle, rebuilt for
your phone. Connect the dots into a single closed loop that never crosses or
branches. Each number tells you exactly how many of its four sides the loop
uses. A 3 needs three. A 0 needs none. Everything else you work out by pure
deduction.

No guessing. Ever.

Every board is generated on your device with a guaranteed unique solution, then
graded by the hardest technique needed to crack it — edge counting, dot degree,
corner rules, chain logic, parity, contradiction. Any puzzle that would force a
guess is thrown away before you ever see it. If you're stuck, there is always a
next move you can prove.

LEARN IT IN A MINUTE
• Short guided lessons that teach the rules by having you play them
• Optional spoken narration, read by your device
• Tap an edge to draw a line, tap again to mark it ×, or drag to sweep a whole run

AN ENDLESS CAMPAIGN
• Starts at a gentle 3×3 and grows to 9×9
• Seven difficulty bands: Tutorial, Easy, Medium, Tricky, Hard, Very Hard, Expert
• Past level 130 the boards stop growing and the logic keeps sharpening — clues
get sparser, deductions get deeper. It doesn't run out.
• Up to three stars per level: solve clean, solve quick

A DAILY PUZZLE
• One board a day, the same board for every player in the world
• Gentle on Monday, brutal by Sunday
• Build a daily streak — and buy it back if you miss a day
• No account, no sign-in, no server

BUILT FOR ACTUAL PLAYING
• Undo and redo, every move
• Auto Check flags a wrong edge the moment you draw it — or switch it off and
submit blind
• Hints that name the next forced move instead of just handing you the answer
• Pause the clock, reset the board, pick up exactly where you left off
• Share a picture of your finished loop

ACCESSIBILITY AND CONTROL
• Colour-blind-safe result colours, with incorrect edges dashed
• Sound and haptics, independently switchable
• Turn off × marks if you only want lines
• Turn off drag-to-draw if you only want taps

Track levels solved, stars earned, your daily streak, and total time spent
thinking.

Puzzles are generated and solved entirely on your device, so the game works with
no connection. Coins buy hints; you earn them by solving levels, by keeping your
daily streak alive, and — if you want — by watching an optional rewarded ad.
Nothing is locked behind one.
