Random chess bot concept

  I was having an idea on head my today and this was: the idea of a chess bot whose moves are random, it will randomly pick out of any of the possible moves it can make in a match, now obviously most of the time this hipothetical bot would lose to most players, but it would be interesting and even funny to see what would it do, especially against itself.

 Now I don't know if a bot like this has been coded before, and I myself have no experience in coding, but I think it probably would not be hard to code a chess bot that makes a random move.

maybe an RNG (random number generator) for the piece moved and the engine just picks the best move for that piece?

It has been done before. In four player chess you can choose different bots to control pieces instead of players, and one of them is a random. Search it up, you should be able to find it
