Yotsu

Yotsu is a minimalist daily puzzle app that offers four carefully curated logic puzzles—Shikaku, Akari, Binairo, and Sudoku—delivered each day without any distractions. Designed with simplicity and privacy in mind, it features no ads, no tracking, and requires no account or sign-up, making it an ideal choice for puzzle enthusiasts who value a clutter-free experience. The app works fully offline, ensuring that users can enjoy their daily brain teasers anytime, anywhere. Its focus on quality over quantity and a straightforward approach appeal to those who want a reliable daily mental workout without the manipulative design often found in other gaming apps.
