Happy ranching!

Patch v1.3.0 (18 July 2018)

DRONES ARE NOW AVAILABLE!!! Drones are happy little helper bots that can be programmed to help with various tasks around the ranch!


Drones are a new gadget that can reduce some of the work a rancher needs to perform on the ranch. They will happily bring food to corrals, take plorts to the market, or help store excess crops in silos. There are many different types of tasks you can program a drone to do, so it will be up to you to figure out how they can help!

Patch v1.2.2 (23 May 2018)

The Party Gordo Has Arrived!

Every weekend, the Party Gordo comes to the Far, Far Range, but you have to find him first! Hunt down the Party Gordo who is hiding somewhere on the map and pop him to receive lots of party presents containing festive ornaments for your ranch.

But the party doesn't end there! You can also discover presents hidden around the world all weekend long! Because though the Party Gordo may be gone, the party... well it LIVES ON.

The Party Gordo is available all-day Friday, Saturday, and Sunday (local time) and will return every weekend with new treasures to discover!


Patch v1.2.1b (4 April 2018)

Patch 1.2.0b (15 March 2018)

Patch 1.2.0 (14 March 2018)

Nimble Valley:

The Nimble Valley is a new zone that is home to the exceedingly rare quicksilver slimes. Not much is known about the Valley outside of the fact that it is owned by the one and only Mochi Miles. Work for Mochi and prove yourself to be a first-rate rancher!

Quicksilver Slimes:

Quicksilver slimes are lightning quick, and feed on electricity. This is generally accomplished by their moving really fast and slowly accumulating the static charge they generate. However, Mochi has decided to speed up the process and created a method for feeding them energy in a far more direct fashion.

Electrical Charges and Power Stations:

Patch 1.1.1 (29th November 2017)

Save System Improvements

Slime Rancher now maintains several prior copies of your save file to protect against system crashes or power outages that result in corrupt data. If the game cannot load the most recent autosave it will revert to the most recent one it can find. As part of this change, the autosave frequency has been reduced to autosaving every 5 minutes.

Patch 0.5.1c (24th April 2017)

Patch 0.5.1b (19 April 2017)

A quick followup patch was issued to address a few bugs found in the release:


Patch 0.5.1 (19 April 2017)


Patch 0.5.0b (08 March 2017)


Patch 0.5.0 (08 March 2017)


Patch v0.4.3b (10th February 2017)

Patch v0.4.3 (9th February 2017)


Patch v0.4.2d (20th December 2017)

Another series of issues were discovered that we deemed worth a quick patch. This includes:

Patch v0.4.2c (19th January 2017)

Another bug related to treasure pods was discovered that required another quick patch. You may experience certain pods are re-closed., but just as before, this should not negatively impact your game in any way.

Patch v0.4.2b (19th January 2017)

We discovered a bug that caused old treasure pods to close again following the release of v0.4.2 and have issued a fix. If you have a save file with the pods re-closed you simply have to open them again if you wish to have all pods opened. This will not cause any other issues with your save file. All blueprints you had previously received will remain available to you.

Patch v0.4.2 (19th January 2017)



Lastly, we are changing the listed minimum memory requirement for Slime Rancher from 2GB to 4GB of RAM. As we've added more and more features and areas to the game the used memory has grown somewhat over time. Additionally, we feel this better reflects the increasing amount of memory that is in use by newer versions of Windows, which use quite a bit of the system memory at all times.

In short, if you've been able to run Slime Rancher, nothing will change.

Patch 0.4.1 (14 December 2016)

For our final planned update of 2016 we're making some fixes and adding some silly stuff for you to enjoy. Thank you again for an oh-my-goodness-is-this-really-happening 2016 and we look forward to creating more Slime Rancher adventures in 2017.

Happy holidays!
