Zellige — Suguru Logic Puzzle
Tectonic & Number Blocks
Free · Designed for iPad. Not verified for macOS.
A new puzzle every day, the same one for everyone. Hand-drawn tiles, in a light and a dark theme.
Zellige is a logic puzzle built from glazed tiles. It goes by Suguru in most of the world, and Tectonic in France and the Netherlands. Three rules, no arithmetic, never a guess.
THREE RULES, AND NO MORE
• Each block of N cells holds the digits 1 through N, once each.
• No two touching cells carry the same digit — diagonals included.
• Every puzzle has exactly one solution, and reasoning alone will reach it.
A PROGRESSION THAT KEEPS UP
From 5×5 grids to find your footing, up to 12×12 that ask for method. Every puzzle is generated and then verified: its solution is unique, and its difficulty is measured by the reasoning it actually demands — not by how many cells are blank.
A PUZZLE OF THE DAY
The same one for everyone, every day. Keep your streak.
TO PLAY WITHOUT FRICTION
• Notes: pencil your hypotheses into the cells.
• Undo: take a move back without losing your notes.
• Mistake highlighting, which you can switch off to play without a net.
• Pinch to zoom on the larger grids.
• Light and dark themes, both properly drawn.
• Automatic resume: your game waits where you left it.
DRAWN, NOT GENERATED
Every icon is a hand-made stroke, every cell a tile set in its grout. The blue comes from the cobalt of old glazes.
ACCESSIBLE
The whole grid reads with VoiceOver. Contrast follows the WCAG guidelines, and a mistake is never signalled by colour alone.
No account, no sign-up, no connection required. Just puzzles.

New: the daily puzzle becomes a daily habit.
• A friendlier daily puzzle: a 9×9 that takes about ten minutes, still with one unique solution.
• Until you've solved it, it waits at the top of the home screen, with your day streak.
• An optional evening reminder, only on days when it's still to do.
• Out of coins? Get a hint for a video, straight away.
