New generation of SUDOKU

I loved to play sudoku, but I started to get little bored of it. I decided to look for different puzzle that also involves logical thinking and numbers... and there it was SIKAKU (rectangles) by Nikoli. It used to come out in Japanese magazine in early 90s. I got my inspiration from there and decided to create my own game called iRectangles.

I spend a lot of time in subway therefore I decided it will be the best to crate it for iPhone, it's available in App Store since 11/07/08:
