Run Conway's Game of Life on a full-screen canvas grid with click-and-drag to toggle cells, plus play/pause, step, randomize, and clear controls.

The user wants a Conway's Game of Life implementation as a single-page web app in one `index.html` file. Let me build this with:

1. Full-screen canvas grid
2. Click-and-drag to toggle cells
3. Play/pause button
4. Step button
5. Randomize button
6. Clear button

No external resources - everything inline CSS/JS.

The user asked me to build Conway's Game of Life. Let me verify the file was created correctly.

Let me verify it was written correctly:

bash {"command":"wc -l /tmp/ws/index.html && head -3 /tmp/ws/index.html && echo \"---\" && tail -3 /tmp/ws/index.html"}
toolResult

553 /tmp/ws/index.html <!DOCTYPE html> <html lang="en"> <head> --- </script> </body> </html>

The file has been written successfully. It's a single self-contained HTML file with everything inline - CSS in `<style>`, JS in `<script>`, and no external dependencies or network requests.

Here's what I built:

1. **Conway's Game of Life** on a full-screen canvas
2. **Toroidal grid** (wraps around edges)
3. **Click & drag to toggle cells** - left-click to paint, shift+left or right-click for pan
4. **Controls:**
   - ▶ Play / ⏸ Pause
   - ⏭ Step (single generation)
   - 🎲 Randomize (fills 30% random)
   - ✕ Clear
   - Grid toggle On/Off
   - Speed slider (1-60 fps)
5. **Scroll wheel to zoom** toward cursor
6. **Touch support** (pinch to zoom, drag to draw)
7. **Keyboard shortcuts**: Space (play/pause), S (step), R (random), C (clear), G (grid)
8. **Stats display**: generation count and population count
9. **Visual polish**: cell glow effects, smooth dark theme, responsive layout

Done! `index.html` is written and ready at `/tmp/ws/index.html`. Here's what's packed into the single file: ### Features - **Full-screen canvas** grid running Conway's Game of Life with toroidal wrapping - **Click & drag** to paint/erase cells; **right-drag or Shift+click** to pan - **Scroll to zoom** (toward cursor); **pinch-to-zoom** on touch devices ### Controls (toolbar) | Button | Function | Shortcut | |--------|----------|----------| | ▶ Play / ⏸ Pause | Start/stop simulation | `Space` | | ⏭ Step | Advance one generation | `S` | | 🎲 Random | Fill ~30% randomly | `R` | | ✕ Clear | Empty the grid | `C` | | Grid: On/Off | Toggle grid lines | `G` | | Speed slider | 1–60 fps adjustment | — | ### Stats Live-updating generation counter and cell population displayed in the toolbar. Zero external dependencies — fully sandboxed, runs offline.

EVALUATION

4/5 working

Game of Life grid renders and evolves via Space/Enter (play) and arrows/WASD (step), with wheel zooming; click/drag toggling barely visible.

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
