About the Game

Simple Rules, Deep Logic

Fill circular puzzles with the correct numbers using just three simple rules. Rondoku is a calm and minimalist logic game that invites you to slow down, think carefully, and find satisfaction in clever solutions.

70 Hand-Crafted Challenges

Every puzzle in Rondoku is designed by hand. With 70 unique levels, the game offers a thoughtful difficulty curve and a sense of intention in every diagram.

A Puzzle Book

Inspired by classic puzzle magazines, Rondoku is presented as a book. Flip through its pages freely and enjoy the quiet satisfaction of solving each puzzle, one by one, until the book is complete.
