You must protect the Slime Castle from enemies, so start preparing your army for battle in this slimy game. This isn’t your regular medieval war game, and things can get slippery if you don’t upgrade your slime army regularly.

You can get handy items for free with Slime Castle codes. Your army needs good gear and other essential upgrade items, so it’s time to step up your game and use codes before they expire. If you want another cute fantasy game (featuring cute mushrooms), then you should grab some Legend of Mushroom codes and start making a mushroom army.

Why are my Slime Castle codes not working?

If Slime Castle codes aren’t working for you, then you should double-check them for any spelling mistakes. I personally copy/paste codes to avoid typos, so that’s a handy method you can rely on as well. If the codes still don’t give you anything, then they’re no longer active. Inform us whenever you discover an expired code, and we’ll update our list.

What is Slime Castle?

Slime Castle is a mobile TD game where you can control adorable slimes and fight waves of enemies to protect your slimy kingdom. To win battles, you’ll need to upgrade the slime’s stats, armory, and skills. If you want your gameplay to be more idle, then turn on the auto-battle feature and sit back as your tiny slimes claim victories.
