$ cat slots.prompt — what the model was asked
Build a fully playable Vegas-style slot machine in a single self-contained HTML file with no external libraries and no external assets.
## Reels
- 3 reels, each with these 7 symbols: 🍒 Cherry, 🍋 Lemon, 🍊 Orange, 🍇 Grape, 🔔 Bell, ⭐ Star, 7️⃣ Seven
- Spin animation: each reel spins independently (reel 1 stops ~800ms, reel 2 ~1200ms, reel 3 ~1600ms), showing symbols scrolling at ~12 symbols/sec before snapping to the result
- SPIN button disabled while spinning
## Pay table (multipliers × bet)
- 7️⃣ 7️⃣ 7️⃣ → 100×
- ⭐ ⭐ ⭐ → 50×
- 🔔 🔔 🔔 → 20×
- 🍇 🍇 🍇 → 15×
- 🍊 🍊 🍊 → 10×
- 🍋 🍋 🍋 → 5×
- 🍒 🍒 🍒 → 3×
- Any two 🍒 in first two positions → 2×
- All other → 0× (loss)
## Betting & credits
- Start with 100 credits
- Bet buttons: 1, 5, 10 credits (highlighted active; default: 1)
- Bet deducted immediately on spin; win adds bet × multiplier
- GAME OVER at 0 credits with 'Play Again' button that resets to 100
## Win feedback
- Win: flash matching symbols, show '+[amount] credits' in gold, display win name ('JACKPOT!', 'THREE BELLS', etc.)
- Loss: shake animation on reels
- Credit balance count-up animation over 400ms
## Pay table display
- Visible panel on page (not a modal) listing all combinations
- Highlight winning row when that combination hits
## Code quality
- Single HTML file; all JS in <script>, all CSS in <style>
- Game state: { credits, bet, spinning, reels, result }
- Named functions: initState(), spin(), checkWin(), animateReels(), updateUI()
- RNG: Math.random() only
- No inline onclick= handlers; use addEventListenerrun 1 of 1
