One graphics card, one AI that plays Slay the Spire 2
Always wondering how to play Slay the Spire 2 better, I trained a reinforcement-learning AI from scratch on a single RTX 5060. It now wins more than 24% of runs.
Why I did it
When I play Slay the Spire 2 I keep wondering how to play better: whether to take a card, which path to take next. Rather than testing it one run at a time myself, I wrote a reinforcement-learning AI to play on its own and scout the way for me.
How
I built a reinforcement-learning agent on PPO and trained it entirely from scratch, using a single RTX 5060 for the whole run.
Today
It now wins more than 24% of its runs.
