Good variety – Sudoku X4U Review

I was looking for a variety of sudoku layouts and this app had my favourite which is the jigsaw sudoku. It also has the X variety which adds some interest. That's why it gets 4 stars. It's kind of cumbersome to switch between levels of difficulty so that's a minus. Also it doesn't help you to keep track of how many boxes have been filled for each digit which is a feature that I like to have, although it does tell you when all instances for a particular number are full.
