## What is Pengudoku?

Think across rows and columns like Sudoku, then deduce each safe cell and rescue the penguins.

Pengudoku is a relaxing logic puzzle where every correct placement helps solve a colorful iceberg. There are only three rules to learn, but each larger board asks you to think one step deeper.

HOW TO PLAY
• Place exactly one penguin in every colored region
• Keep penguins out of the same row and column
• Never let penguins touch, even diagonally

Tap once to mark a cell with an X. Double-tap to place a penguin. Satisfy every rule to complete the rescue.

WHY YOU’LL ENJOY PENGUDOKU
• A smooth difficulty curve from 4×4 to 9×9 boards
• An endless sequence of logic stages and special challenges
• Cracked ice that adds new twists to familiar rules
• Charming penguins to collect and choose
• Offline play whenever and wherever you want

Solve one quick board during a break or settle in for a demanding iceberg.

Game interface languages: Korean, English, and Japanese.
