Part II: Table Game Cheating · Dice & Craps Cheating Methods
Shaved Dice (Bricks / Flats)
How it works
Dice that have been shaved or ground down on one or more sides to alter their shape from a perfect cube toward a rectangular prism. When one side is shaved, four adjacent sides become shorter with less surface area, causing the shaved side and its opposite side to appear face up more often because the die tends to settle on the larger remaining surfaces. Variations include: Six-Ace Flat (shaved on 1 or 6 side - rolls more of those numbers).

On the record
In 1976 the FBI Laboratory listed flats, or bricks, among the common types of altered dice, and said most bricks were “6-ace flats.”
