Bowman 2

A nice physics game where you shoot an arrow to a target, easy right?  Of course it isn't that simple, where would the fun in that be?

Diamond Hollow II

"Shoot, upgrade, conquer enemies, defeat bosses, acquire achievements, collect gems, all in an attempt to save yourself and your gun from the clutches of the evil Professor."

A fun game if you can get used to the use of the mouse to aim.

Desktop tower defense

I've seen a few tower defense games but this is one of my favorites.  You have to protect your base from waves of bad guys by using different tiles that damage the enemy and force them to go around when you build a wall of them.

Factory Balls 4

The fourth in this line of fun puzzle games is a great diversion as you find the way to paint your ball to look like what it should be on its box.  You will use various paints and objects to produce various patterns on your ball.  Have fun getting to the highest level!!

RED

Red is a favorite of mine because it is simple but challenging with a great sense of style and appeal.  It is easy to pick up how to play but surviving will be another matter altogether.  Have fun with this one!

"This variation on classic flop Poker depends heavily on the new Object extension and attribute creation methods introduced in the ES5 revision of ECMAScript. Please feel free to inspect the source and have fun!"

This fun little game is being used as a demonstration of microsoft's explorer capabilities, but fun is fun.
