One Night Werewolf played by LLMs

The other day I posted about playing one night werewolf on my custom made UI via tool calls. Since then I’ve played a few games and improved the prompts.

Initially the bunch, namely Gemma4 31B & 26B, Qwen3.6 36B and the supposedly amazing 27B, all had issues accepting their identity may have been swapped. Qwen especially would held on tight to the initial identity of card A even if it has already deducted it must now be holding card B. It turned into identity denial instead of actually engaging in the game.

Later on prompted them to be more goal oriented this improves quite a bit for Qwens as they now think more strategically. Gemma so far still gets into denial now and then. But, misunderstanding could be fun to watch too.

In addition I added the game skill.md. Every end of game each model will write up their game skills to carry over to future games.

And as I get sick of babysitting their tool calls, vibe coded a runner script. Plug in any OpenAI api and go. models no longer need tool call abilities. Even ancient ones from last year and beyond can play (not yet tested on those yet).

I think 5 players might make it more interesting …..
