Inklo Puzzle

One puzzle a day, the same for everyone. Fill every square with a single line, then draw your own puzzle and send it to a friend. No ads, no account.

One line. Every square. Numbers in order.

Inklo is a clean, quietly addictive logic puzzle. Start at 1, pass the numbers in order and fill every square of the board with a single line. The rule fits in one sentence, the joy of solving is new every time.

DAILY PUZZLE Every day, everyone in the world solves the same board. Share your time, keep your streak and compare with friends.

35 LEVELS FROM BEGINNER TO CHAMPION Seven tiers: Beginner, Easy, Medium, Hard, Expert, Master and Champion. Difficulty rises step by step. Higher levels add walls, and from Medium on every puzzle has exactly one solution.

DRAW A PUZZLE Draw a path with your finger and Inklo turns it into a puzzle. Choose any size from 4x4 to 9x9 and one of three difficulties. Send the link to a friend: it opens your puzzle, and after solving they see the path you drew. Then they can draw one back.

HISTORY Every puzzle you solve is kept with its date. Come back any time to see it again, replay it or share it.

COLORS AND SOUNDS TO EARN Finishing level tiers unlocks new color themes: Mint, Coral, Lavender, Night, Gold and Diamond. Pick a soft sound style (Kalimba, Drop, Bell, Wood) or play in silence.
