Free Online games available

10/13/2008 6:00:00 AM

We now have the initial version of the playable Stars & Stripes, Sudoku Islands and Trividoku puzzles online. These use Microsoft Silverlight v 2.0 beta - sort of Microsoft's answer to Flash programs - so things are 100% perfect yet. They've been tested under Internet Explorer 7 and Firefox 3, but there are known problems with some earlier browsers.

Give them a try and see what you think!

For you Trividoku fans, currently we only have two puzzles available to play, but we'll have more online soon.
