WELCOME IN THE ARGIO-LOGIC WORLD !
This website was born in 2008 thanks to Gabriele Argiolas, who managed it and created the puzzles: more than half a milion different sudoku puzzles, ready for the years to come too.
From the three variants of the beginning, today the website counts 111 of them every day.
Argio-Logic is a site populated by a very heterogeneous community (from childrens to "well on in years adults") who made the game, especially the games of intelligence, his hobby.
Here you'll compare yourself with "duffers and phenomena", select your specialty and, other permitting, excel in one or more of these.
