B3 has revealed the five winners of its third AI Game Buildathon, a rapid development event where participants created playable games using artificial intelligence tools. The challenge focused speed, originality, and AI integration. Developers were given a short window to produce working games, many from scratch.

The winning projects were selected from dozens of submissions and will soon be available through the BSMNT platform, B3’s experimental hub for indie and AI-driven games.

Participants used large language models and coding copilots such as ChatGPT, Claude, Grok, and Cursor to support everything from logic scripting to world-building.

Here’s a breakdown of the five winning entries:

Slow Down by @kryptonlove

The top prize was Slow Down, an arcade-style game developed in under five hours. In the game, players control a yellow circle that moves through a field of hazards, collecting orbs while avoiding collisions.

The developer, known online as @kryptonlove, submitted the game just before the deadline. Cursor AI played a key role in speeding up the development process. The result is a minimalist game with tight movement and simple rules. The quick turnaround and clean mechanics helped it secure first place.

Paint Your World by @UndiscoveredGo2

Next, Paint Your World was developed for one week. The concept is centered around changing a blank environment by painting it. Here, players explore and interact with a world that changes based on color and user input.

The team behind the game, Undiscovered Goats, relied on AI for narrative development and gameplay design. The team credited AI tools and time-boxed planning for helping them go from concept to completion within days. The game's creative approach to interactivity earned it second place.

Egg Maze by @afurourrego

Third place went to Egg Maze, a 3D puzzle game where players tilt a virtual board to guide a ball through a maze. The game blends real-world physics with digital controls.

Essentially, developer @afurourrego created the game in just two days. AI tools like Claude, ChatGPT, and Grok were used during development to solve bugs, generate level logic, and write portions of the game code. The final product is functional and inventive, showing how quickly AI can support complex builds.

Warpionary by @LiamcKerr

Warpionary mixes wordplay with quick reactions. While full gameplay details were not shared publicly, early reports suggest it involves guessing or creating words under pressure, possibly in a multiplayer setting.

The game received attention for its unique mechanics and concept. It also stood out for its use of AI in testing and feedback loops, which helped refine its playability within a short build window.

Honorable Mention: Bully Beater by @maths_code

Bully Beater rounds out the top five. The game appears to focus on conflict resolution and strategy, with potential social themes built into its core loop. Few public details are available, but judges noted its ambition and message.

The developer, @maths_code, used AI to simulate behavior patterns, generate dialogue, and automate parts of the design. The game’s focus on meaningful interaction earned it recognition in the final rankings.

A Glimpse Into the Future of Game Development

The AI Game Buildathon highlighted how development cycles are changing. Projects that once required weeks or months can now be prototyped in days or even hours with the help of advanced AI tools.

Instead of replacing developers, these tools served as accelerators. They handled repetitive coding tasks, solved syntax issues, and even helped shape design ideas. The result: faster iteration, broader experimentation, and new creative possibilities.

As AI tools continue to evolve, events like Buildathon offer a preview of how game development may soon look — faster, more accessible, and driven by both human intent and machine support.
