I asked Gemini to solve today's Countle puzzle (https://www.countle.org/). It got stuck while iterating randomly trying to find a solution. While I'm writing this it has been trying already for 5 minutes and the web page has become unresponsive.

I also asked it for the best play when in backgammon opponent rolls 6-1 (plays 13/7 8/7) and you roll 5-1. It starts alright with mentioning a good move (13/8 6/5) but continues to hallucinate with several alternative but illegal moves. I'm not too impressed.
