Place a number in every little room. The same number can never touch — not up, down, across, or diagonally. That's the whole rule. And it runs surprisingly deep. Suguru (also known as Tectonic) is a number-logic puzzle played on a grid split into rooms. A room of size n holds 1…n, once each. And no two matching numbers may sit next to each other in any of the eight directions. That one twist — no diagonal neighbours either — gives Suguru a softer, different feel from sudoku. Best of all, every Suguru here comes with one promise: it's always solvable by pure logic, with no guessing. No placing a number on a hunch and watching it all collapse. Just the quiet satisfaction of narrowing things down, one certain square at a time. ■ Features A logic rule all its own: no matching neighbours, diagonals included Every puzzle solvable by logic — zero guessing, never stuck Four sizes: 5×5, 6×6, 7×7, 8×8 A fresh Daily puzzle, with a solving streak Pencil notes, hints, and undo Stats: best times, streaks, and solves by difficulty A calm design in traditional Japanese colours English and Japanese Fully offline.
