Chocolate bar games are variants of the CHOMP game in which the goal is to make your opponent eat a poisoned square of chocolate. The rectangular chocolate bar is a thinly disguised form of the NIM game. In this paper, we investigate chocolate bars whose widths are proportional to the distance from the poisoned square. We find the nim-values when the constant of proportionality is even, and present some conjectures for other cases.
