Cryptex vs Suguru

Cryptex is a code-breaking game for one player. It is based on Mastermind, one of the most famous classical board games. The logics and game rules are very similar to an earlier invented game called Bulls and Cows, played with a pencil on paper. The app generates a random code with 4, 5 or 6 letters, and your task is to guess the correct combination as quickly as possible. The game is simple, fun and addictive. With every try you get two pieces of information: 1. CL - Correct Letter - the total number of correctly guessed letters in the entered combination. 2. CLP - Correct Letter and Position - the total number of correctly guessed letters with correct positions in the entered combination. Happy code-breaking!

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.
