A different take on Futoshiki.

Futoshiki with Apple Pencil, beneath the stars of Spitzkoppe. Write answers and notes directly on the grid, erase and undo as you work, and return to your puzzles later.

A campaign path through 12 constellations, Daily Challenges following the lunar cycle, and Free Play to generate Futoshiki puzzles for yourself. All completely free.

12 CONSTELLATIONS TO DISCOVER Follow a path through 115 authored puzzles, from 4×4 to 6×6. Each puzzle you finish lights a star. Complete a constellation and its figure emerges from the sky.

DAILY CHALLENGES FOLLOW THE MOON A new puzzle each day, with the real Moon keeping time. Browse the lunar calendar to revisit earlier challenges.

FREE PLAY Choose a size from 5×5 to 8×8 and a difficulty. Generate a Futoshiki for yourself; finish it and another is prepared with the same settings.

If you enjoy Sudoku, try its inequality-loving cousin. Use each number once in every row and column, and follow the greater-than and less-than signs between cells. A guided introduction gets you started, with one optional hint per puzzle.

Play with Apple Pencil or touch. No ads, timers, leaderboards, purchases, subscriptions or account. Everything works offline. Handwriting recognition, puzzle generation and saved progress stay on your iPad.

Designed for iPadOS 18 or later.
