Sudoku
An offline-ready Sudoku game for desktop and mobile browsers, with five difficulty levels and optional learning aids.
A classic Sudoku game designed for both desktop and touch screens. It includes five difficulty levels, a bank of 120 checked puzzles, and on-device generation for further games. Optional candidate assistance, notes, layered hints, and a technique guide support beginners without changing the core rules.
Relaxed mode flags only repeated digits in a row, column, or box; strict mode immediately counts incorrect entries. Completed games can be saved to a local leaderboard. After the first online visit, the game can be installed to the home screen and played offline.
