Numbercrazy was built to satisfy a growing demand for Sudoku, a fun logic puzzle that is highly popular in the world.
Initially built as an exercise in Javascript in Apr. 2006, the current incarnation is a fully featured client game available in the latest generation browsers.
This site is built using YUI libraries and CSS/Javascript. With a keen interest in keeping the interface simple yet usable, we believe we are one of the best web based sudoku sites available.
