BrikWars is a wargaming system for use with Lego bricks or similar building blocks and figurines. It is designed to be simplistic, with many optional rules. Rules are humorous, with frequent quotes from Sun Tzu and other thinkers on war.

Brikwars is a derivitave of Legowars, an earlier Lego-based battle game. (Lego Wars was not affiliated with the Lego Group, and was withdrawn from the public domain for using of the Lego trademark without permission.)
