In this solitaire card game, the player is presented with a pyramid of twenty-
eight cards. There is also a draw pile and a discard pile. Cards may be
discarded from the pyramid if they are completely uncovered and their face
value is one point higher or lower than the card on the top of the discard
pile. If no cards can be discarded, the top card of the discard pile can be
replaced with a fresh card from the draw pile. The object is to discard all of
the cards in the pyramid; if the draw pile runs out before this happens, the
game ends in failure. There are two difficulty levels — in level one, all
cards in the pyramid are face-up, but in level two, cards remain face-down
until they are uncovered. The game keeps track of ten high scores.
