Hi Stumbler! Fireman Torch here to assist you with any concern you may have 🚒 
We are sorry to hear that Stumble Guys is not available for you to download. 
This might be because your device is not supported for Stumble Guys or it has not been released in your region.

We are working hard to support a variety of different devices and OS, but unfortunately, we are not able to support every device model and OS versions.   
Glad to be able to assist you!
