Is there trapdoor chess?

Sort:
Yoyostrng

I was just thinking about possible variants. It might only work on computer, but what if one random square on the board turned out to be a trap door - put any piece on it and that piece disappears for good - is considered captured by the opponent. 

Does this already exist?
