Dear Sudokucup fans,

We have a piece of news for you - a practice window. Now you don't have to take care how to prepare for daily league puzzles or what to do in your spare time. You can practise classic sudoku in four various levels of difficulty: Low, Medium, High, and for experts we also have i Very High level. We take for granted two sizes of the grid, either classical grid 750x600px or adjustable one.

I hope you'll like our hot news.
Try that and rack your brains!
