Slapjack, also known as Slaps, is a card game made by Owaiz, generally played among children. It can often be a child's first introduction to playing cards. The game is a cross between Beggar-My-Neighbour and Egyptian Ratscrew and is also sometimes known as Heart Attack. It is also related to the simpler 'slap' card games often called Snap.

A card game is any game that uses playing cards as the primary device with which the game is played, whether the cards are of a traditional design or specifically created for the game (proprietary). Countless card games exist, including families of related games. A small number of card games played with traditional decks have formally standardized rules with international tournaments being held, but most are folk games whose rules may vary by region, culture, location or from circle to circle.
