FreeSO (“Free Simulator Online”) is a reimplementation of The Sims Online™’s game engine, using C# and Monogame. While FreeSO aims to be faithful to the original game, it includes many quality of life changes such as hardware rendering, custom dynamic lighting, hi-res output and >2 floor houses.

How do I play?


If you simply wish to play, you can install FreeSO and the original TSO files using our installer+launcher available from, and it will connect to our official servers. You can also register an account on this page, and find links to our communities where you can find support for the game, and reports on server status.

Note that our installer downloads the original TSO files from EA’s official servers. These files are required to make FreeSO behave like TSO, and are not unofficially distributed.

Fair use policy

On its own, the FreeSO client does not display any copyrighted material, and is not distributed with it. The game files are provided by the user, and the client simply reads the files the user provides. In this sense, our replacement client is essentially a glorified The Sims Online™ file reader, as all original graphics, sounds, UI layouts and game objects are simply read and simulated by the client. The same goes for all our other tools and extensions for The Sims franchise games.

The game server transmits metadata generated from the execution of these scripts (avatar money values, lot/object state, avatar appearances, hash of game files for version identification) but does not transmit any copyrighted material.

We will not accept any code or content that violates the policy above in our repo.

  2. GREAAT you are amazing!! Please don’t ever stop with this project because it’s just perfect! I’ll tell my friends right now 😀

  3. I am just curious, I wanna download very very bad — but once it downloads the file and I try to open it gives me an error which I am about 99% sure why — Because I am using a MacBook… Could you PLEASE Direct me to a download link for Macbook? I do remember the original TSO being Mac compatible so I would assure theres a download file for it out there somewhere… Thanks!

      1. Oh Miss Fanny I’m not sure who that person is… who thought I’d be thought of so many years after TSO? I’m swell, we need to catch up I have news of the others… don’t forget LCG is pemp. 😉

  4. Hey, I love what you’re doing! Sadly, when the original version was out and about I barely had dial up and I never had the opportunity to play, but I have heard so much great things about it! If you’ll accept, I’ll be willing to handle anything you need help with.

  6. I have some old screen shots and content that might be useful in future plans. I played this game since day one back in the day and had 4 to 5 accounts. I made a living as a high school student off this game a long time ago. I’m so glad to see it back, and would love to help by donating some funds or providing servers. Anything I can do to help.

  7. There seriously needs to be a Mac compatible version. I would love to play FreeSO, but since I’ve got a computer with an apple logo on it, I’m out of luck. Nostalgia should not be inhibited by a fruit. Thats my two cents. But seriously, make the Mac version!!!

  8. I would pour hundreds of dollars into this if I could play it on my Mac. Seriously. I appreciate this project so very much. I miss my simming days more than my partner or any current friends not from that long 15 years ago could ever understand.

    1. is this still being played? I would love to play TSO again! i also miss pizza! Back in the day I had a lot for it and had so much fun.

  9. Someone on 2nd Life just told me about this game. I used to LIVE on TSO!!! I can’t wait to make pizza again, own my own house and just do all the things I used to do years ago!!! Thank You for bringing it back 🙂

I really don’t know what to do anymore, can it be solved?

  16. I want to download this game but I’m worried if it will give me a viruses. Does anybody know how secure it is?

  17. I wish it work, but it doesn’t. Tried in 3 computers but none of then are ”good”enough to play.

  18. Is there any sort of offline version of freeso? like a remastered version of the sims 1 with a massive world? if not do you plan to make a remastered version of it?

  19. Hi. Is their A way That I can sign into my original account from TSO on FreeSO? I have All the info including the sn# of the product.

  20. Thank you ever so much for providing this game to play once more. I can’t imagine the amount of work and costs involved to manage this game. I know EA forbids any donations going towards the game management, but maybe I’d be able to provide a donation for the upkeep of the website? 😉

  21. This is amazing. I was on TSO from launch to close. It was one of the most fun games I’ve played. Can’t wait to get started here, after all there “Gnome place like home”.

  22. Does anyone know how to fix a problem with the game the problem is when it’s downloading from the launcher at 58% a message said “extracting client files, please wait” and i waited 2 hours and nothing happened what do i do?

    1. Hey,

      Given the time of posting, you may have been downloading during about an hour period where our buildbot was serving a bad version. You should close (from the tray) and reopen the launcher and give it another shot. If you continue to have errors, you should join the discord so more people can see your message.


  23. Hey, I stumbled across this by accident today when showing someone how amazing and fun EA-Land was over a decade ago. I was so excited to see that someone has actually picked it back up and given it flourishing life once again, It looks so incredible! On behalf of everyone who doesn’t know about this yet, THANKYOU!

  24. I also stumbled across this when showing my boyfriend a video of gameplay from the original TSO. So, so, SO excited this is a thing! Can’t wait to download it and start playing. Thank you so much!!!!!!

  25. the tutor AquilaSim said he didn’t believe that I play with the children of my friend and my wife at our house, with two PCs … and then banned accounts that my wife and I played a year ago, I don’t recommend it to anyone. disappointed, understandable because EA games does not participate in this online game. And besides banning most accounts, he banned wrong accounts, like my wife’s who played every week.

  26. gooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooood

  27. To all the Developers, Testers and anyone else who checked in a change or contributed to the final beta for this game: Thank You! Thank You! THANK YOU!… This is a truly lovely game you have created here.

  28. I saw a random YouTube video about this game wow nice job to your team I wanted to play a game like this it’s the best thanks !!!!

  29. Since it doesn’t seem like this is really a thing anymore (Correct me if I’m wrong), is this safe to run on MacOS?
