Clobber is a new two-player board game. In this paper, we introduce the
1-player variant Solitaire Clobber where the goal is to remove as many stones
as possible from the board by alternating white and black moves. We show that
a checkerboard configuration on a single row (or single column) can be reduced
to about n/4 stones. For boards with at least two rows and columns, we
show that a checkerboard configuration can be reduced to a single stone if and
only if the number of stones is not a multiple of three, and otherwise it can
be reduced to two stones. But in general it is NP-complete to decide whether
an arbitrary Clobber configuration can be reduced to a single stone.
