Not always. When the well consists of mountains and valleys perfect for fitting S/Zs into, Bastet will deal you an O (square). Though it is possible to get the best of Bastet: its algorithm for determining the worst possible piece works by attempting to drop every piece straight down from all possible horizontal positions, and does not take sliding maneuvers into consideration. Taking advantage of this, you can create a large overhang at the top of the well, then play by building the majority of your stack under it.
