A viral Opus 5 “challenge loop” prompt is turning 24-hour AI game builds into a trend

A viral "challenge loop" prompt for Opus 5 is pushing AI game development into overdrive. The setup uses a main agent, sub-agents, and a judge agent that keeps rejecting results until they match a target quality bar, which reportedly helped one developer build a playable space game in 24 hours and inspired others to ship browser-playable prototypes like kart racers and Cyberpunk-style demos. The post argues that the loop effectively turns Opus 5's planning and iterative abilities into a more reliable workflow.
