A ‘Game without Thrones’ is a playful, intense, hands-on simulation of self-organization using Lego®. Moreover, it’s a Game without Thrones because of self-organization rules. We use Lego® to learn how agile organizations work, with no command and control, but instead chapter meetings, tribal treaties, small councils, and leadership as a service. The game aligns autonomous teams into self-managing streams. But who builds? Everyone builds. These roles are analytic perspectives, not hierarchical positions. Everyone loves to work with the Lego so it isn’t fair to shut anyone out of it.
