“I don’t want spoil all the fun, but … things didn’t go well:”
Our reading, the sentence that was checked:
In The Guardian's test, people using AI tools without coding knowledge did not succeed well at building a Pac-Man clone.

Conditions

From the speaker

- build a clone
- Pac-Man
Our interpretation
- Read the statement as a limited description of substantial difficulties in the reported attempts, not as a claim that every attempt failed completely.
- Assess the findings of the particular Guardian report as published on March 11, 2025; this does not date every participant's coding session.
- The separate characterization of the participants as seven people without coding knowledge is not assumed to be established by this outcome.
Counts as supported if: The original account documents substantial implementation or debugging difficulties in the attempts.
Counts as contradicted if: The original account describes consistently straightforward production of satisfactory, functioning clones.
Retrospective: these criteria were written after the outcome was public.
Current assessment
Was it true for the period described?
Outcome: Supported
The dated evidence matches what the claim committed to, under the criteria frozen before grading.
Scored on a plain reading. The speaker named no measure for this claim, so it was judged on the reading an informed reader would take, stated below under our interpretation. Both reviews had to find that reading fair.

Rationale
The Guardian report published March 11, 2025 documents substantial difficulties across several Pac-Man attempts [e1, e2]. Justin Martin reported missing pellets, broken warp tunnels and frustrating debugging, then switched to Tetris after an hour [e1]. Hester reported generating an approximation in seconds, but it needed corrections and still lacked features including power pills and more levels [e2]. Another attempt received one star, with the reviewer questioning its colours, maze, ghosts and Pac-Man [e1]. Martin also called the process “surprisingly easy,” and other participants expressed enthusiasm [e2]. These accounts support the limited claim that the attempts involved substantial difficulties, alongside some quick progress and positive reactions [e1, e2].
Limitations
- The report does not establish universal failure or a population failure rate [e1, e2].
- It does not establish that all seven participants lacked coding knowledge: Hester described software development experience, and Martin had studied programming in high school [e2].
- March 11, 2025 is the publication date; the evidence does not establish when each coding session occurred [e1, e2].
