This is a set of dials I use to race on the lego race track using lego cars and lego power up bricks. These dials are used in conjunction with a paper clip and pencil spinner. Players place a regular paper clip onto the dial face and then hold it in place with a pencil point. Flick paper clip with finger tip to spin around the dial face. Wherever the paperclip stops is read as the current car speed. Stopping on a power brick awards that power brick to the car - use as in the regular game. Players may z shift 1 dial per turn. In other words you start in neutral and shift up through the gears to increase racing speed. Downshifting is used to keep you from hitting another car.
