350 pure deduction grids. No ads, no subscription, no connection.
A pure logic game. No ads, no subscription, no connection. Just grids that yield to reasoning.
Tektologic is Suguru — also known as Tectonic.
■ THE RULE
The grid is cut into irregular blocks of 1 to 5 cells. A block of N cells holds the digits 1 to N, once each.
Two neighbouring cells never carry the same digit — and neighbours include diagonals.
That's all. There is no row or column constraint: two 1s can share a row, as long as they don't touch. That is what sets Tektologic apart from sudoku.
Every grid has one unique solution, reachable by deduction. Never by guessing.
■ WHAT YOU GET
→ 350 grids across 7 tiers, from Discovery to Legend
→ An interactive tutorial that teaches the rule by playing
→ Hints that explain the deduction instead of handing you the answer
→ Pencil notes, undo, error detection

→ Stats, streaks and Game Center leaderboards
■ BUILT TO BE READ
Six fonts to choose from, two designed for dyslexia. Nine themes in light and dark. A colour-blind mode. Everything adjusts.
