   I wrote about this issue a bit here: http://www.stefanom.org/2000000-systems-played/ It's a combination of (a) people straight up exploiting the fact that the server trusts that the data sent from the client is co

   Thank you! I should add that the entirety of the code will be published on GitHub, like my other projects ( http://github.com/stefano-meschiari/ ), so people should feel free to fork, make pull requests, etc. If anyone l

   I bit the bullet, and wrote a bit of extra javascript to restart the game server-side. By the by, if you like what I've done, I will soon be available to freelance. A few other projects of mine are here: http://www.stefanom.

   I am applying for funding to develop a more comprehensive educational application. Hopefully the success of the game will give my application some extra clout.

   The simulation is always done with the same time resolution (time step). What the speed factor does is just change how many integration steps are taken between frames, so speed should indeed not affect the evolution. If you have a reproduci

   I have. It will be posted on GitHub as soon as I have a bit of free time. I want to make sure the code is well commented & readable.

    Soneca, there are a few links on the sidebar. My hope is that people will look for answers among the many excellent resources that are already available online. I also hope to develop the game further to make the physics that drives the pla

    It is a simple leapfrog integrator (which is indeed symplectic). I found that, at least in a test implementation, higher order methods were too computationally expensive to run the simulation at a good frame rate.

    Thanks for the tip, Matt. I believe I have it set up now.

    I definitely took a shortcut there. I'm not a professional programmer, and any time I dedicate to this I tend to consider as "stealing" my attention from my actual job as an astrophysicist... I'll do a bit of testing and

    Hi Shivetya, Admittedly, the point system could have been better designed. However, for this first attempt, I could not come up with a better alternative. "Exploiting" the point system within the game is not that easy, so the peop

    Good catch. I did not expect the game to become this popular, so I took what I considered to be an easy shortcut.

    I am the developer of the game (StefanoM). I'm glad people are enjoying the game, and I'm sorry for the downtime -- I did not expect it to become this popular. If you have any improvements or suggestions (especially on the program
