How do I install Slime Merger?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on CurseForge — not every file is mirrored on our own servers.

What Minecraft version does Slime Merger work with?

The listing gives Minecraft 1.21.5, 1.21.8, 1.21.4, among others. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Slime Merger — Minecraft Java mod, screenshot 1

The big slimes have merged into an even bigger slime!!

Slime Merger is a small feature I had in the old Survivalist mod, that I wanted to bring back as a standalone mod.

Don't worry, it can't be exploited to have infinite slime. When slimes die they release slimes half their size, but when they merge, the size only grows by 1, and it takes 4 slimes to make one.

Can I use this in <X>?

Yes. Unless <X>'s license is incompatible with this mod's, which is unlikely.
