ab: Two games are described. 1. Pick-up Marbles. This is a simple
paper-and-pencil game for two persons. The second game is named Bead-up
Abacus. Suppose we have an abacus with only two rods and some beads on
them. The beads can only occupy uniformly spaced positions on the rods.
Each player alternately moves a bead up the rod by one position. A bead
cannot be moved if either another bead is directly on top of it or it
has already hit the top of the abacus. Any player who cannot make a
move loses.
