A means of generating random numerical results for the purposes of gambling. The first references to number-sticks reach as far back as ancient Shigek. The most common variations consist of two sticks typically referred to as the Fat and the Skinny. A groove is carved all the way through the Fat so that the Skinny can drop up and down its interior length. The Skinny is then capped on either end to prevent it from falling out. Numerical values are marked along the length of the Fat, so that when the sticks are thrown, the Skinny can indicate a result.
