when i was in year 6, we played the el cheapo version where we just hold a pen and hold it in the air, and your hand automatically moves to a letter (the alphabet and numbers were written on paper). I can't explain it, but i think your mind makes it move with you actually telling your mind to do it.
I remember there was this dumb queen bitch who was a total bitch and she was playing a game, and she apparently hated this girl who was playing the game with her, anyways,
the bitch started spelling that girls name out. haha that poor girl didn't get good sleep i betcha.
