The name of this blocks thing comes from joining the words Su (number in Japanese), doku (unique in Japanese). Hence, the correct spelling is sudoku, rather than suduku, sodoku, soduko, soduku or sedoku. Although they were created in the mid 80's, it was not until 2005 when they started to become fashionable after appearing daily in several international newspapers. Nowadays, it is very rare not to find a newspaper that contains a sudoku among its pages. To solve this math game usually takes between 10 and 30 minutes depending on the difficulty and agility of the player.\n\nTerms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/\n\nPlease see our Privacy Policy at https://www.kyokujoy.com/privacy.html\n\nPlease see our Terms of Service at https://www.kyokujoy.com/terms.html","facts":{"developer_id":1652472542,"developer_url":"https://www.kyokujoy.com/","first_released":"2022-12-28T08:00:00Z","support_url":"https://www.kyokujoy.com/","privacy_url":"https://www.kyokujoy.com/privacy.html","website_url":"https://www.kyokujoy.com/","app_version":"1.44","release_notes":"Fixed minor issue.","rating_current_version":4.77522,"rating_count_current_version":3706,"star_counts":[47,23,104,368,3163],"genres":["Games","Puzzle","Board"],"languages":["EN","FR","DE","JA","KO","ZH","ES","ZH"],"content_advisories":null,"device_families":["iphone","ipad","ipod"],"chart":null},"freshness":{"apple_read_at":"2026-10-21T10:28:12.740Z","catalog_read_at":"2026-10-18T04:55:12.120Z","reviews_checked_at":null,"summary_written_at":"2026-10-19T21:52:11.536Z","placed_at":"2026-10-18T07:37:11.801Z","scored_at":"2026-10-22T10:05:13.319Z"},"editorial":{"one_liner":"Free classic Sudoku puzzle game with seven difficulty levels, daily challenges, hints, and offline play.","what_is":"Sudoku Classic Brain Puzzle is a Games app that offers classic Sudoku number puzzles on a 9x9 grid.
