It’s quite a complex system. It probably isn’t possible to exclusively do this in the studio. Unless you’re pretty experienced with scripting, despicably in websites, than I’d recommend relying on other’s code for this.
Place visits is the amount of times that the player has joined the game, so in order to make your own place visit number for a player you need to run this code in a normal script:
You would need to save this value with data stores and I haven’t made the leaderstat named “PlaceVisits” in the code so you would also need to make that on your own. I hope this helps!
EDIT: I had a little misunderstanding with what you were asking for and gave the amount of times the player joined YOUR game not how many times other players joined their games. So sorry for this!
