Towers for Palm

From HANDCASE:

In this game you have a stack of discs, from largest to smallest, that slide on to the first tower of a three tower board. Your goal is to move the entire stack of discs from the first tower to the third tower. However, you can only move the topmost disc of any tower, and smaller discs must always be placed on larger discs. Always try to do less with possible moves. In English.
