One of the easiest card games to play between two people, War can be taught to even the youngest kids. The deck is evenly divided between the two players to begin the game. In rapid succession, both players lay down their top card once after the other, with the highest card being the winner. If you win the round, you collect the two cards. You keep this up until one player eventually has all of the cards and has won the war. In the event of a tie, three cards from each player are dealt facedown with the fourth acting as the battle card. Whoever wins the hand gets all of the cards. If the name of the game doesn't jibe with your pacifist sensibilities, you can call it Head to Head or just makeup a name. Your kids will enjoy playing whatever the name.
