Sudokool updated :
1. The game now runs on both linux and windows.
(I have not tested on other OS, but thnx to platform independent java technology on which this game is developed, hope it will run smoothly on others too.)
2.Game window made resizable.
3.Added file select/browse in save/load option to make the things easy in case of large no. of saved games.
Link in first post has also been updated.
