## What is 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.

FREE, WITH ADS ONLY IF YOU CHOOSE
Two free games a day (the daily challenge is always included on top). Need
one more game or a hint? A short rewarded ad — only if you choose to watch
one. No banners, no ads interrupting your game.

LUMEN UNLIMITED (optional)
For total comfort: unlimited games, zero ads, 3 hints per game. One-time
purchase, €3.99 — yours forever, no subscription.

ACHIEVEMENTS AND LEADERBOARDS
Sign in silently to Game Center to unlock 15 achievements and climb 6
leaderboards — one global, one per variant. No sign-up required; the app
stays fully playable offline if you'd rather skip it.

Lumen Sudoku is a clean logic game built to last: five ways to play, twelve
hundred and fifty levels, and your own pace.
