Why It's Different
Built on principles that reward creativity and collaboration
Create to Progress
The best way to advance is to build something others love
Earn bricks based on creativity, quality, and community engagement—not just time spent. Your best builds become your best rewards.
Collaborate by Default
Forks, diffs, and guided assembly instead of raw copy
Share builds as step-by-step blueprints. Others must assemble your creations, learning as they build. Automatic attribution and royalty splits on derivatives.
Fair Play Economy
One currency: bricks. Earn by building, not buying
No pay-to-win. Bricks are earned through active play, quality builds, and community contribution. Trade with other players to get what you need.
Safety & Stewardship
Clear land rules, permissions, and age-appropriate defaults
Plot-level permissions prevent griefing. Moderation tools keep the community safe. 13+ with parental guidance for younger builders.
