Gargamel was his first main character to be turned into a game piece. The Game Master finds the Smurf Village and takes Sassette and Slouchy hostage. Some Smurfs try to save them but fail (even Papa Smurf).

This frees everybody trapped as game pieces, sending them back to where they came from, and sending the Game Master back to his home, where he cries to his parents over losing.
