Again, I'm biased but with Buku you get multi-player (co-op play, team battle and entirely new concept – an active duel where the player’s performance directly impacts his opponent’s puzzle) and the ability to use a range of controllers (big button pad, DVD, DDR mat, etc).

Oh, and did I forget to mention you can win a 40" 1080 Samsung TV by getting 200 out of 200 achievement points.

That's why you would spend $10 rather than play the free stuff.

Hi, I'm with the publisher of Sudoku and the XBLA version is totally different than the PC game. We've added different types of multi-player, multiple control schemes, and most importantly, you can win a 40" 1080 Samsung HDTV by getting all 200 achievement points (http://bukusudoku360.com/?page_id=46)
