DUBLIN – Dec. 7, 2021 – Error300 Games’ Welcome to My Cave is launching today on the App Store and Google Play!

Experience the humble beginnings of humanity’s first steps into the unknown. Reap the rewards as your tribe progresses from scrounging up the bare necessities to producing the finest technology (and architecture) the ancient world has to offer!

In Welcome to My Cave, you are the young chieftain of a new tribe – setting out to prove your leadership skills to your father. While every settlement starts off with toolmaking and agriculture, you’ll bring a fresh perspective to post-cave living as you develop more advanced technologies and improve the lives of your tribespeople. The sky is literally the limit as your cultural and scientific innovations leap beyond what any caveperson has dreamed up before!

Research and invest in new technology to increase production. Build up your civilization and go from stone buildings to modern dwellings. Maybe you’ll even get to Mars! With more than 100 buildings to unlock, who knows where you’ll end up. Your tribe, your rules! Just remember: A tribe is a terrible thing to waste.


“I’m a huge fan of Kairosoft games,” says Marina Makarevskaya, director and designer at Error300 Games. “I’m not even going to pretend I’m not – because anyone seeing Welcome to My Cave is going to spot the similarities. The truth is that I’ve always wanted to make a game like this. We had to come up with an innovative theme in order to stand out from the countless sims already in existence. It needed to be something that hadn’t been done before. One of our team members suggested cavemen. I thought ‘Hmmm, cavemen simulator…’ – and the rest is (pre)history!”

Key Features

  • Become the chieftain of your own tribe.
  • Enjoy a charming art style.
  • Filled with humorous visuals and descriptions.
