Patterns was a sandbox-style building game published by San Francisco-based Linden Lab, which had previously been known primarily as the creator of the online virtual world Second Life.

The PC product, which was distributed via BuildPatterns.com, continues the company’s positioning as a maker of "shared creative spaces" that favor open-ended content creation and sharing over traditional goal-oriented gaming.

Creators can construct simple or elaborate structures using various shapes and patterns that are discovered as the game progresses.

On October 10 2014 Linden Lab announced that they were abandoning development of Patterns and shutting down the servers.
