Zoom, inline player and more ways to view
The model's own page, run in a sandboxed frame only when you ask (a page that needs its own origin opens in a new tab on a separate demo site). Phones get a full-screen player capped at 1.5x pixel density (2x on larger screens) so it stays smooth; the original page runs uncapped. It starts in its auto-tour (T switches to play mode on a keyboard).

No rubric for this prompt
Visitor votes and reviewer grades are not available yet.
- AI judge
- AI judge: the test runner (model claude-opus-5-5), scoring by visual review of the 1600 px render against the pre-registered rubric. No AI-judge score exists for this result: there is no rubric for this prompt, so no score is shown and none is made up.
- Visitors
- Public voting with a blind reveal is coming: you score the output first, then see the other scores.
- Reviewer
- The reviewer's own grade appears here once it is added.
Scores compare results for the same prompt only. AI-judge boards rank runs within one prompt, equal totals sharing a rank; scores from different prompts are never averaged.

The exact prompt
as run, 492 characters. Every result for this prompt
Build a complete, polished Battleship game playable in the browser (index.html plus any JS/CSS, no build step). Player vs computer on 10x10 grids: ship placement (drag or click, with rotate), a computer opponent with a sensible hunt/target strategy, hit/miss/sunk feedback with animation and sound, turn indicator, win/lose screen and restart. It must work with mouse and touch and look good on desktop and phone. Write everything into the working directory and finish with a short README.md.
