Show HN: Radioactive Pooping Knights
patrickdavey Saturday, December 06, 2025I've been having fun building out a really simple chess learning app for my daughter (7). It started with just "maze like" puzzles [1] and I've added a few more.
This "radioactive pooping knights" idea came from an Irish primary school chess website [2]. Really simple idea, two knights moving around the board leaving poo behind... Don't be the one forced to step on it.
* best played with sound on.

*highly subjective, may not be better for you to play with sound at all ;)
p.s. Any "buy me a coffee" goes to my daughter. Annoyingly they only pay out once you get above $10 USD and I think it's currently sitting at 9.85 or something!
