While having some free time I found the website minigamesfun.com. It is a flashgames website where You can play free small games - mainly flashgames.
Among the 5000 games to be found on that site I found some really interesting games. I like playing sudoku a lot. And at this site I found an interesting variant of sudoku called plop art sudoku.
The game is played like sudoku, but you do not have numbers in 3 by 3 quares, but little creatures. Those creatures have to be put so that one creature is found only one time horizontally, vertically and only one time in the same square.
It is really nice to play this kind of sudoku and You can spend a lot of time with this cute game.
The minigamesfun.com site is colorful and offers many more interesting games. Sometimes it loads a little bit slow and what You have to know is that You have to register, if You want to play more than 20 games a day. But that does not really matter as it is free and You can save Your favorites then, have an avatar and many more.
So I think overall this website is worth while having a look at it.
