Physics Games is a collection of browser games that all have at least a rudimentary physics model. Some of the games I've enjoyed are Roly Poly Eliminator, Totem Destroyer 1 & 2, Demolition City and Red Ball. Most are fairly simple but some are complex, notably IncrediBots 1 & 2, which might as well require an engineering degree (slight hyperbole). My absolute favorite type of game on this site is the destroy-castles-with-a-trebuchet game, handsomely represented by not one but three games, Castle Clout, Castle Clout: Return of the King (no Tolkien connection) and Crush the Castle. All this is but a small sample of what's on offer.

Crayon Physics, the delightful latest game from independent game developer Petri Purho at Kloonigames, a sort of finnish Ferry Halim. Draw objects with your crayon to get the ball to the star. The site is also home to other made-in-a-week games such as Cacodemon, which is as frustrating as it is addictive. If Crayon Physics seems too short, check out the small level pack or hack the xml to make your own. Windows only, works in Wine too

PhET - Physics Education Technology offers this astoundingly large library of online physics simulations. Play orbital billiards. Land on a cheesy moon. Experiment with sound. Or try more advanced quantum physics simulators. Still bored? Try the "cutting edge" catagory. Here's the complete index. (Warnings: Frames, Flash, Javascript, Java applets, graphics, sound, quantum timesuck.)

Ever wanted to be a little chick with a gun, knocking down hundreds of blocks? Well, now's your chance in Kumoon: a fun, free little physics-based game (for Mac and PC) in which you must knock down all the blocks in a room with limited resources. Screenshots, review + movie courtesy of this excellent list of physics-based games of all kinds. Something for everyone.

Games games games. You've probably seen some of them before. But they're all based on good physics.
