Let an agent take turns in a browser game
A writer used ChatGPT agent mode to compete in Ben Orlin’s online math games, stepping in between turns so the agent could continue.
- What they did
- They loaded online versions of Ben Orlin’s Math Games with Bad Drawings into GPT-5 in ChatGPT agent mode and let it handle moves in its own browser window. The agent clicked through the game screens and picked actions while its chain of thought remained visible. Since it could not detect when control passed to the other side, the writer advanced the game manually by telling it when to continue.
- How it went
- The setup worked about as intended, which was a better result than earlier attempts with car rentals and tax paperwork. The play itself was not strong: the writer defeated it without much trouble as both Bob and Alice, and the agent also overstated its ability to notice turn changes.
- Tips
- Turn-based games need a human to signal every new move, so plan on active supervision. Also keep in mind that a model may appear stronger if it has already seen the game before.
Try it yourself with ChatGPT Agent
Open [URL] for [game name] and play [number] rounds against me in the browser. After each move, stop and wait until I say “your turn” before making the next one. Briefly tell me what you are trying and what you expect to happen. Do not log in, pay, submit, delete, or share any personal information unless I approve that step first.
Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
