I used to manage an escape room and the best thing I ever saw was in our Jigsaw room. They start that one handcuffed or footcuffed to separate bits of wall, and they had to tie some lab coats together to lasso a wheeled trolley across the room as their first puzzle.
One day I had a couple come in. When I initially asked who wanted the foot cuff Vs the handcuff, she insists that he gets handcuffed. I chain them up, give them their starter hint that the trolley will be immediately important, leave and go to the office.
Whereupon I watch as the woman turns to the man and says "Gareth, give me your leg."
Gareth bends down, removes his prosthetic leg, and throws it over to her. She drops onto her stomach as far forward as the footcuff allows, grabs her boyfriend's detached foot, and uses it to fish the trolley over.
Greatest solution to that puzzle I ever saw
