Welcome to the world of sudokus!
Sudokus have become one of the most popular pastimes in the last few years, not only on newspapers and magazines, but also as casual computer games.
SudokuWorld is one of those sudoku computer games you can play without pen and paper. This version is supposed to have about 100,000 puzzles (though I obviously didn't count them all), classified into three different categories according to their level of difficulty.
The game features a generously sized interface which makes it easier to play. I specially liked the ability to add the so called "pencil notes" (small, temporal numbers you're not sure of yet) and also the possibility to ask for a hint. On the downside, I was surprised to see I couldn't play with the keyboard's num pad, but only with the top number row, which is not that comfortable.
SudokuWorld will keep you entertained for a while with 100,000 puzzles in different difficulty levels. And if you get stuck, don't be ashamed of asking for a hint!
