A fan-ball engine is a very simple type of machine in Powder Game and Powder Game 2 which uses several fan-balls surrounded by any solid other than ice. The purpose of a fan-ball engine is simply to produce large amounts of wind in a short time period, where fan as an element would generally consume too many dots or produce wind in a set direction. Fan-ball engines can easily and quickly produce enough wind to transform stone into powder. How it does this, is by using a unique property of the fan-charged ball. When a fan-ball collides with other elements and/or objects, it produces wind at several angles. Using several fan-balls constantly moving and impacting one another can create very powerful winds.
