Recently, the leading developer of PolyMC went on a political rant and removed all his co-developers from the project. We do not condone any form of bigotry.
Meanwhile, the other developers released a fork of PolyMC called Prism. This is the solution we propose you pick instead of PolyMC.

If you want to play Minecraft on your Steam Deck, with mods and everything, I recommend you install a little app called PolyMC Prism. It’s an unofficial launcher with fewer issues than the official one.
Here’s how you do it.
- Go to desktop mode. Click the
Steam button
, go down toPower
, and thenSwitch to Desktop
. Wait for the Deck to reboot. - Click on the
menu button
and open upDiscover
. - Search for
PolyMCPrism. (If the keyboard doesn’t pop up, click theSteam Button + the X-button
.) Install the app. - Launch
PolyMCPrism and add your account in the top right corner. You can use both your Mojang and your Microsoft login. - Next, go into the main
PolyMCPrism settings, clickMinecraft
in the left sidebar and click the option to closePolyMCPrism whenever the game window opens. - Also, check if Java is set to the latest version.
- Click
Add Instance
in the top left. Either choose vanilla Minecraft or follow this guide to install mods. - If you care, you can add Minecraft to the Steam Library. Open up
desktop Steam
, go toLibrary
, and at the bottom left corner, click on the plus sign, thenAdd a Non-Steam Game...
. Navigate to your installation folder and add PolyMC.
..and that’s that covered. You should now be able to play Minecraft on your Steam Deck with mods.
Enjoy your blocky worlds!
