Zellige — Suguru Logic Puzzle

About this app

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.
