X Marks the Spot (poker)
A variant of Southern Cross, played only in home games, in
which each player is dealt five cards face down, and five cards
are dealt face down in the center, in the form of a cross, forming
three vertical and three horizontal cards, with each player
allowed to combine any of the widow cards together with his
original cards in forming a five-card hand. The widow cards
are turned up one at a time, with the center card turned up
last, each followed by a betting round. The center card and
others of the same rank are wild. Also called criss-cross.
