Tectonic Star

Think you're good at logic puzzles? Tectonic Star says prove it.

Tectonic Star brings the addictive logic puzzle known as Tectonic (also called Suguru) to your fingertips. Sharpen your mind with irregularly shaped grids where every region must contain a unique sequence of numbers — no matching digits allowed to touch, not even diagonally.

FEATURES

• Multiple difficulty levels, from beginner-friendly grids to expert challenges
• Clean, distraction-free interface designed for focus
• Intuitive number input with error highlighting
• Track your solving time and personal best records
• New puzzles to keep your brain engaged

WHY TECTONIC STAR?

Unlike Sudoku's fixed grid, Tectonic's irregular regions demand a different kind of spatial reasoning — making every puzzle a fresh mental workout. Whether you're a seasoned logic puzzle fan or just discovering the genre, Tectonic Star offers a satisfying, screen-friendly way to train your brain.

Perfect for a quick mental break or a longer, focused session — pick up where you left off, anytime, anywhere.
