Based on the basic game of Hearts, this version adds two features to standard Hearts whereby a player may actually score plus. The play of the cards takes on heightened interest, since it combines "nullo" play (to avoid gathering hearts and the Q ) with positive play to win plus points.
The hearts and the Q are minus cards, as in standard Hearts. In addition, the 10 counts plus 10 for the player who wins it. (In some localities, J instead of 10 is the plus card.)
When a player wins all fifteen counting cards - the thirteen hearts, Q , and 10 - it is called a slam and he scores 26 plus (instead of 16 minus).
