Lumen Sudoku Killer & X

Jigsaw, diagonal, offline

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Five sudoku games in one free app, fully playable offline: Classic, Killer, Sudoku X (both diagonals), Jigsaw (irregular regions) and Odd/Even. 1250 levels in total, 250 per variant, plus a fresh daily grid every morning. FIVE VARIANTS, ONE GAME • Classic: rows, columns and 3×3 blocks. • Killer: sum cages with few given digits, for players who love the math. • Sudoku X: both main diagonals must also contain 1-9. • Jigsaw: the 3×3 blocks give way to nine irregularly shaped regions. • Odd/Even: marked cells only accept odd or even digits. Each variant has its own 250-level ladder, its own accent colour and a one-page "How to play" primer. 1250 LEVELS, A CAREFULLY TUNED CURVE Every grid is generated and checked to have a single unique solution, with difficulty rising smoothly from level 1 to level 250. A global level tracks every win across all five games and moves you up the ranks, from Novice to Grand Master. DAILY CHALLENGE One grid a day, the same for everyone, playable even offline. A monthly calendar keeps track of your wins and feeds your daily streak. 100% OFFLINE No connection needed to play. No account, no sign-up form, no server. Your progress never leaves your device. The app is available in 10 languages. FREE, WITH ADS ONLY IF YOU CHOOSE Two free games a day, on top of the daily challenge, which is always included. Need one more game or a hint?
