One grid. Two rules. No guessing.
Suguru is the daily logic puzzle for people who love newspaper puzzles: a grid divided into cages, two simple rules — and a depth that grows with every difficulty level.
ONE GRID, TWO RULES
• A cage with four cells holds the numbers 1 to 4.
• Equal numbers never touch — not even diagonally.
Every puzzle has exactly one solution and can be solved by pure logic. Guaranteed: every single puzzle is machine-checked before it reaches you.
THE DAILY PUZZLE
A new puzzle every day, as a quiet anchor: gentle on Mondays, the big master puzzle on Sundays. Your streak counts the days — and generously forgives one missed day per month. The widget brings the daily puzzle to your home screen.
HINTS THAT EXPLAIN
Suguru doesn't just give away answers. Hints unfold in three stages: first where to look, then why only one number fits. Placing it is up to you. That's how you get better with every puzzle.
LIKE A PAPER PUZZLE BOOK
Warm paper tones, refined serif typography, subtle sounds and haptics. No confetti, no flashing — just a golden moment when everything fits. With the Paper, Midnight and Sepia themes.
