Both of you do need the following though:

  • One computer per player

  • Same content, expansion packs and mods
  • And optionally, Hamachi to play online.

1. Download and install the mod

Go to and start with downloading the multiplayer mod from there and install it. On each computer, extract the downloaded archive. Inside you will find a .ts4script file. Copy that to your games mod folder. Start Sims 4  and go to the game’s options make sure you have custom content and script mods enabled. Turn both on. You should restart the game when it asks you to do that.

2. Create a save file

When done, hit save and move the Sims into a lot. Buy and build everything in advance. Pause the time, then hit save and exit the game. It is essential to pause the game before saving. You need to pause the game and then save it, to ensure that the host and your friend both join a synced game file.

3. Host a game

When done saving the game, one player must host a game which the other can join. After login, click on the host game tab. Hamachi is automatically detected if it’s running.  Click on the network interfaces to select the network you would like your host your game. Click the start server button to create a room and start the server. Then the other player can join the chamber.

4. Joining a game as a client

When you are connected, a couple of network tests will automatically run to see if the system set up correctly.

5. Sync the save file

The only thing remaining before playing is to sync the save file. On the server, pc hit the sync Save button and select the game save which you want to synchronize to the other players. Their status should change to synced once they have received the save file.
