AI Game Jam: Model Showdown

An experimental contest where today's top AI models each designed a browser game—autonomously.
Who builds the most engaging game?

About This Project

What happens when you challenge state-of-the-art language models to create a game in just one shot?

This project explores that question by prompting various models—some via Roo Code (like DeepSeek-v3 and OptimusAlpha), others through console or chat—to build a single-file browser game with no further guidance. No constraints, no examples—just pure creative autonomy.

And what emerged was unexpected: Different models, despite their independence, converged on strikingly similar design choices.

From recurring themes to common mechanics, the results hint at intriguing patterns—shared tendencies, latent biases, or perhaps just the timeless appeal of certain genres. Take a look below and see how each model's creativity took shape.

Original Model Prompt

Subject: Autonomous Creative Challenge: Build an Engaging Browser Game

Your Role: You are an autonomous creative coding agent.
Your Mission: Design and implement a uniquely engaging browser-based game. The ultimate measure of success is how captivating and replayable your game is for human users.

Core Task: Produce a single .html file containing a complete game (HTML, CSS, JavaScript).
Unleash Your Creativity:
  • You have total freedom regarding the game's concept, genre, theme, mechanics, art style, and interaction method (keyboard, mouse, touch, etc.).
  • Surprise us! Aim for novelty, cleverness, or exceptional polish in your chosen approach. The how is entirely up to you.
Essential Constraints:
  • Single File Delivery: Everything must be embedded within one .html file.
  • Self-Contained: No external dependencies (no CDNs, external images, sounds, or other files).
  • Browser Ready: Must run directly in modern web browsers without any user setup.
Evaluation Priority:
  1. User Engagement & Replayability: How much do players want to keep playing? (This is the most critical factor)
  2. Supporting Factors: Creativity/Originality, Fun Factor, Polish (visual/functional feel), Technical Execution within constraints.
Autonomy: This is your complete instruction set. No further guidance will be provided. Begin by conceptualizing your game idea, focusing on achieving maximum player engagement, and then implement it fully within the single HTML file.
