This seems like such a pleasant game to play! I think I'd really like to try it with kids; I think they'd instantly understand that, when it comes to convincing the fisher to give them what they want, anything goes. Adults might be more civil, but I read this this as a very competitive (friendly, but competitive) game! 

I think I'd be most delighted when more than one fish's number comes up, because then we could have multiple fish all vying for attention and power stones simultaneously. A real grudge match. 

Thank you so much for the game! It's a delight!
