FAQ: GMF Builder's Challenge

About the GMF

Why did you change the Game Maker Fund system?

Following the Sandbox's rapid evolution, we've implemented significant changes to the GMF system. This update aims to create a more inclusive environment and reward a wider range of creators. Since the summer 2023, over 500 diverse Experiences have enriched the platform. To accommodate this growth and support continued creator involvement, the outdated GMF system with its 70-Experience cap had to be revised. The revamped GMF offers broader accessibility. Creators crafting high-quality Experiences and implementing effective marketing strategies will now have increased opportunities for recognition and reward. We encourage all creators to explore the revised GMF system and participate in shaping the future of the metaverse. This updated system provides more individuals with the chance to contribute their unique perspectives and talents.
