Chika Sudoku: Offline Puzzle

Chika Sudoku is a cozy offline sudoku game with a mouse hunt on top — a classic number puzzle to relax with, a brain game for daily brain training, and a logic puzzle that works with no wifi at all.

Solve sudoku grids, uncover hidden critters in the empty cells, and help Chika — the black cat with a white chest blaze — reach her milk bowl.

SUDOKU THE WAY YOU KNOW IT
• Classic sudoku gameplay: every digit once per row, column, and block
• Gentle start on 6×6 grids, then full 9×9 sudoku puzzles
• Pencil notes on every cell, undo, and mistake checking
• Difficulty from Kitten to Master — for beginners and experts alike
• No time pressure: pause any puzzle and pick it up later

THE MOUSE HUNT
• Some empty cells hide mice, yarn balls, butterflies, or a gold mouse
• The right digit in the right place means a catch and a Pounce boost for Chika
• Sprint fills a cell, Whisker places safe notes, Shield saves one mistake
