Fix 30 HTML5 Slot Games

I have roughly 30 slot game files built entirely with plain HTML, CSS, and JavaScript—no external libraries or frameworks. When I launch them, certain functions refuse to fire and the console fills with both syntax and runtime errors.

Here’s what I’ll provide:
• Full source folders for each game
• Step-by-step reproduction notes
• Detailed browser console logs

What I need in return:
• Clean, well-commented fixes that eliminate the current syntax and runtime errors
• Assurance that every game spins, pays out, and resets exactly as designed
• Compatibility when hosted locally (e.g., from a simple HTTP server) and when deployed to a public website
• A short report outlining what was broken, what you changed, and any best-practice recommendations for future maintenance

All code must remain vanilla JS/HTML/CSS; you’re free to reorganize or modularize, but please don’t introduce heavyweight frameworks. Efficient debugging tools like Chrome DevTools, ESLint, or similar are welcome if they streamline the process.

Once each game plays flawlessly in both environments, the project is complete. I can test on multiple browsers and confirm before sign-off.
