ChatGPT agent tries playing browser math games
Daniel Reeves tried ChatGPT’s browser agent on an online math game to see whether it could play a turn-based game through the page controls. He opened Math Games and selected Bad Drawings, then let the agent inspect the board and click to make moves. This is a small but useful test of computer use: the task requires reading the current state, choosing a move and noticing when control passes back to the other player.

Daniel Reeves tried ChatGPT’s browser agent on an online math game to see whether it could play a turn-based game through the page controls. He opened Math Games and selected Bad Drawings, then let the agent inspect the board and click to make moves. This is a small but useful test of computer use: the task requires reading the current state, choosing a move and noticing when control passes back to the other player.
The agent managed to make moves, but it did not reliably recognize when it was the other player’s turn. Reeves says he had to type “your turn” to get it moving again. The strategy was also weak enough that he beat it without much difficulty. The result is not a game-playing success story; it documents a specific interaction failure and the manual nudge needed to continue.
For anyone trying a similar game, the practical lesson is to choose a simple turn-based task, watch the browser state, and be ready to reorient the agent when the page changes. Reeves does not report a score benchmark or a general result across games, so this account should be read as one hands-on test of a particular game and agent setup.
