My sister and I used to play a game version of this when my mom left for work and we had a friend over. The friend and one of us would take turns tying up the other sibling to a chair a pitch dark room with the lights off with those big weight lifter belts and regular belts from my mom's clotet. Then we would run out the room, slam the door shut and yell from outside the door "ok monsters you can come out now!" And just keep yelling shit like that and it would freak each of us the fuck out when we were tied up. We would kind of just wing it when we felt the person had enough because we would gag them too and all u could hear is muffled screams of death. The shit I put my sister through. She turned out alright tho
