Do not know.
Uninstalling the game from the PC or phone does not erase the account.
What can happen to erase account it is to have the account in the log in event and go to NEW PLAYER. Doing that, it will overwrite the account because the account was already related to an e-mail account. That permanently will erase everything like brand new account.
Uninstalling and re-installing the game and go to Log in having already account, it won't harm. Many players screw up the accounts doing this by mistake.
Reset the account, that it is administration work and should not erase account. My account was reset one time unable to make it work. it got stuck in a loop post log in not uploading account files.
Competitive or not, I still don't have them feet even after opening like three premium packs. I didn't even realise Sparked Runners is a premium until I started grinding seriously on SM and just thought I got lucky by getting a transformed epic.
... So that's why I see them feet everywhere...
(Sorry couldn't resist it)
like the progress an as free. Many can learn around how to make it possible. That brings back memories from my OKI reaching top as free player. Let's see how far goes. It is not easy to manage 3 accounts. In this game 1 account it is good enough related to time and do all activities.
I only have this bad equipment because of my bad luck, like, from every fortune box I get, or the 3 premium packs I've got, I had get 2 legendaries, an Massive Stone Feet, and the Lazy Falcon, most of the epics I get are garbage, and most of the fortune boxes jus gave rare items.
And I'm also using resources in a very bad way, for example, I have 16+ legendary items, but I only have one divine torso, and 0 myths
I know that some people used sparked runners in the past for energy builds with a specifc range. Right now the meta is massive feet so its better to use that if you are very competitive else u can use whatever u want. Personally I like sparked runnera but i dont have them right now. People forgot that the game is about building something you like and having fun.
