Tektologic vs Suguru++

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 → 9 themes, 6 fonts including OpenDyslexic and Andika → 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. ■ OFFLINE, FOREVER No connection required. No account. No data collected. The first 100 grids are free; a single purchase unlocks the other 250, for life. iPhone, iPad and Mac.

Discover Suguru++, a logic puzzle with simple rules and surprisingly rich challenges. The principle is easy to understand. Each region is filled with a sequence of numbers starting at 1: use 1 and 2 for two cells, 1, 2 and 3 for three cells, and so on. Two identical numbers can never touch, even diagonally. Every puzzle has a unique solution that can be found through logic alone. With 10,000 puzzles across 10 difficulty levels, Suguru++ takes you from your first games to Grand Master challenges. Begin with small, approachable puzzles, then progress at your own pace towards more demanding deductions. LEARN AS YOU PLAY An interactive tutorial introduces the rules one step at a time. The first levels let you discover how Suguru works naturally, without reading a long explanation beforehand. TOOLS FOR CLEAR THINKING • Pencil in candidates directly inside the cells. • Undo and redo your moves freely. • Clear candidates that are no longer possible. • Use optional hints whenever you need them. • Track your progress and solving time for every puzzle. A GENEROUS EXPERIENCE All 10,000 puzzles are available from the start. There are no in-app purchases and no forced ads. Optional rewarded videos are available only if you choose to earn coins for additional hints. Whether you are discovering Suguru or already enjoy logic puzzles, you will always find a challenge suited to your level. Take your time, consider every possibility, and let logic guide you.
