After Building game how to turn it into a Running game

Ok I know this is a complete noob question but I can't figure out how to turn my built game into a running game, can someone tell me how to do this?

Go to File -> Build Settings or File -> Build and Run to be able to run your game outside of Unity.

In addition to Sethbeastalan's reponse, you could also try to download the dropbox here:

and then build your game/project as a web player.
