GPTGames

GPTGames is a free, open-source collection of interactive HTML games and utilities for individuals who want to play and explore AI-generated browser experiences.

Key capabilities include:

• Browser-based gameplay delivered as simple HTML, JavaScript, and CSS files, no installation required
• A growing library of games and tools that users can browse and try from the web interface
• Example gameplay such as Two Truths and a Lie, where an AI generates statements on any topic and players spot the lie across 10 rounds with multiple difficulty levels
• Open-source access on GitHub, making it easy to inspect, fork, and modify the code

Pricing: Free.

What makes it notable: the project explicitly documents that approximately 99.3% of the code was written and improved by language models such as ChatGPT and Claude, and it is hosted publicly on GitHub (TobiasMue91/tobiasmue91.github.io) as straightforward, hackable web files.
