Lumen Sudoku Puzzles

Lumen Sudoku brings five sudoku games together in one clean app: Classic, Killer, Sudoku X, Jigsaw, and Odd/Even. 1250 levels in total — 250 per variant, from your very first grid to true expert territory — for progress that never runs out.

FIVE VARIANTS, ONE GAME • Classic — traditional sudoku: 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 — 3×3 blocks are replaced by 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 level 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 tracks your streak of daily wins.

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.
