I dont know if this game is allowed or not but in this game you come up with games for Saw.

I'll start. You are strapped to a chair with metal chains. The metal chains are stuck to your back. Your upper body is naked. The room ventilates cold air meaning you are cold.
You have a machete to cut through your back to release the chains freeing yourself.

Like the letter H is your back with the chain there.
and you have to raise your arms over your head to do it. You cant free yourself from the front because theres a whole metal block thing there. You have to do it from behind. Cut through your skin.
