Classic free physics sandbox game The Powder Toy is now on Steam

I used to spend hours making different bombs in that game. I still load it up any time I get a new computer to see what the FPS on my favorite saves looks like on the new hardware. Back in the day I was lucky to get 30 fps on a busy save but nowadays even my laptop processor can handle the big cities and explosions.

This is the best summary I could come up with:

The Powder Toy is a classic physics sandbox game, which simulates air pressure and velocity, heat, gravity and a countless number of interactions.

It's free and open source, with a pretty active community around it and a lot of fans and now it's been released on Steam too.

It has Native Linux support and my test of the Steam release showed it working fine on Kubuntu 24.04.

• High-Powered Explosions: Blow things up in spectacular fashion with meticulously crafted bombs, triggered on your command.

• Custom CPUs: Build your own logic circuits and processors, pushing the boundaries of in-game computing.

• Anything Your Imagination Can Dream Up: Create realistic landscapes, explosive-resistant bunkers, or technical machines, the possibilities are endless!

Oh wow I haven't thought about Powder Toy since I was on /g/ like 15 years ago.

Oh man, I was just thinking about these little games the other day. I know what I'm doing this evening.
