The Lord of Sudoku

'The Lord of Sudoku' offers you the hardest Sudokus throughout the Web - and we promise to keep up to that!

We're more into logical reasoning than effort - that's why our app offers lots of tools to make solving Sudokus comfortable instead of frustrating. Number overlays, our beloved 'Broom' (mopping up never was as much fun!), vague Clues, the advanced 'Two-Way-Helper' and others help you to focus on the main challenges instead of the footwork.

Special Achievements round up the challenge for ambitious players. The precise requirements are left to discover for you - but rest assured that we keep loyal to our motto 'Logics above Footwork'. You don't need to solve a hundred riddles to obtain all achievements!

A unique encyclopedia offers detailed explanations to versatile solving strategies, the useful tools included and the surprising history and mathematical science behind Sudokus.

The ads we included in 'The Lord of Sudoku' are unobtrusive and shouldn't be too annoying - if you want to get rid of them completely, you can purchase the 'King mode' which also gives access to the very last difficulty level.

We're proud of providing this charming, efficient and deep piece of Science - good luck with finding the numbers!
