Gravity Simulator

I Make Games.


And simulations, and apps, and a mean strawberry shortcake! I've got a couple things in the work at all times, and playtesters are always welcome. Come join us in the forums if you're interested in helping out.

About Science.


Simply put, science is awesome. Yet, can you name a FUN game that taught you any science? I had a tough time answering that question, so I decided to start making interactive science stuffs myself.

Play Them.


You'll find a bunch of my projects on this site, and many are completely free to play. Whether you've got an iPhone, an Android, or just an internet, I've got something for you. If you enjoy them, share them with science-minded friends.

Welcome to TestTubeGames

Founded in 2011, TestTubeGames is an independent game studio focused on science education. The goal? Hands-on science through games and simulations.

Really, though, it's just one guy (Andy: "Hi") following his dream to make abstract physics concrete.

Browse through this site to find all the games and sims I've made. Fling planets and change the laws of gravity, run near the speed of light, or fly through electromagnetic fields. The games span different platforms, so whether you want to play in your browser, on your phone, or downloaded your PC/Mac, we've got you covered.

Go take a look at the games. Or learn the latest news from TTG about upcoming projects on the blog.
