Returns whether the game is currently running
The game is considered running when it is not in edit mode in Roblox Studio. This means, if the simulation has been run using the ‘Run’ or ‘Play’ buttons the game is running.
IsRunning will always return the inverse of
RunService/IsEdit with one exception, if the simulation has been ‘paused’ then both
RunService/IsEdit and IsRunning will return false.

Whether the game is currently running
This code prints out details of a script’s running context, like if it is running on the server, client, in studio, etc. It uses RunService to do this.
Try pasting this code into a Script or LocalScript. See how it runs in online mode and on a Roblox server (open the developer console).
