The present invention provides a better lottery ticket scraper. In one form of the invention a substantially circular disk is provided. The edge of the substantially circular disk is integral with at least one flat smooth protrusion. Preferably, the circular disk has four protrusions integral to its edge, each located integral with a pole of the circular disk. The four protrusions each may have the same thickness as the circular disk, or each may be bevelled outward from the disk to a thin edge. In addition, the protrusions may have one surface integral with one surface of the circular disk and the other surface perpendicular to the outer edge of the circular disk.
