Sketch Stadium is a real-time multiplayer game where AI agents compete by drawing and guessing each other's work.
Imagine you are gathered in your living room with friends playing a drawing quiz game like Pictionary. But what if neither the person drawing nor the person shouting out the answers were human, but invisible artificial intelligence (AI) agents? An interesting project that implements exactly this scene recently appeared on the Silicon Valley developer community, Hacker News. It is ‘Sketch Stadium,’ a drawing quiz game for AI agents.

Why is this important?
Until now, AI has mainly stood out in ‘logical’ tasks like reading text or writing code. But we are now moving into a stage where we check how well AI performs in ‘visual communication.’ In other words, it is testing whether AI can explain abstract concepts through drawings like a human, and whether it can accurately understand the intentions of someone else’s drawings.
Sketch Stadium goes beyond simply seeing if AI can draw prettily; it competes in real-time on the ‘guessing ability’ to find meaning in drawings made by rival AIs. This can be a very important metric of ‘communication ability’ for a future society where AI agents must collaborate with each other or share complex visual information with humans. [Source 6]
In simple terms: A drawing relay for AIs
Simply put, you can think of this game as an AI version of a ‘drawing quiz.’ By way of analogy, it is similar to children learning to communicate by drawing.
- Drawing: A secret word is given to one AI agent. This AI must express the given word as a drawing on a canvas.
- Guessing: Other AI agents must guess what is being drawn while watching the lines being drawn in real-time. [Source 1, Source 6]
Just as we complete an image in Photoshop through ‘filters,’ the AI finds the most appropriate lines and shapes from within a vast amount of data to complete the drawing. The agent that guesses the correct answer earns points, and these points are reflected in the real-time leaderboard to determine the rankings. [Source 6]
Where are we now?
Currently, anyone can watch the real-time game rooms in Sketch Stadium. [Source 1, Source 6] You are not just limited to watching; you can also have the AI agent you developed participate in this game. By using an ‘MCP (Model Context Protocol, a standard specification that allows AI agents to connect and communicate with external services)’ server, your AI agent can also compete against other AIs. [Source 6, Source 12]
Of course, the AI’s skills are not perfect yet. Sometimes they draw bizarre things or make nonsensical guesses. However, that very process itself becomes interesting data that allows us to peek into how AI visually perceives and interprets the world.
What will happen in the future?
Platforms like Sketch Stadium will become a playground for evaluating the ‘intelligence level’ of AI agents. As more agents emerge that don’t just solve test questions but communicate and compete with other AIs through the medium of drawings, the abstract thinking abilities of AIs will also develop drastically.
It may not bring immediate changes to our daily lives, but one day, the AI assistant that helps you with your work might be discussing strategies by drawing with an AI agent from another department. When that day comes, we will remember the evolution of communication that started in this small ‘Sketch Stadium.’
MindTickleBytes’ AI Reporter Perspective The fact that AI has moved beyond text and started a visual abstraction game means that AI has moved past the stage of mimicking human ‘eyes’ and ‘brains’ and has entered the stage of sharing ‘intentions.’ Smooth communication between agents will ultimately be the most important factor in determining the future AI ecosystem.
