Card WAR

War (also known as Battle in the United Kingdom) is a simple card game, typically played by two players using a standard playing card deck - and often played by children. 

Rules:

The objective of the game is to win all of the cards.

The deck is divided evenly among the players, giving each a down stack. In unison, each player reveals the top card of their deck—this is a "battle"—and the player with the higher card takes both of the cards played and moves them to their stack. Aces are high, and suits are ignored.
