Play Heads or Tails:

Heads or Tails is a coin-tossing game. Most coins have a side where the imprint of a person's head, such as a current or former head of state, is impressed — this side is called the "heads" side. The other side is called the "tails" side, irrespective of its design. Technically, the heads and tails sides are known as the obverse and reverse, respectively.

Generally, one person throws the coin up in the air, and the second person must predict which side of the coin will lie face up after it rests back on the ground. A correct prediction results in a win.

A related game, Cross and Pile, was played in England for many centuries. The cross was the major design element on one side of many coins, and the Pile was the bottom part of the die used to cast the other side of the coin. In Italy this game is called Testa o croce, in Spain Cara o cruz and in Catalonia the game is called Cara o Creu (all "head or cross"). In Germany the game is called Kopf oder Zahl and in Greece Korona i grammata ("head or number", because the other side shows the coin's value). In Latvia the game is called Cipars vai ģerbonis ("number or the coat of arms"). In Ireland it is usually called Heads or Harps (Irish: Ceann nó Cláirseach), since the obverse side of Irish coins (both Euro and the former currency, the Irish punt) always shows a harp. In Brazil, it is called Cara ou Coroa ("face or crown"). On Brazilian coins, one of the sides are called "Cara" (marked with a face); the other side is called "Coroa" (crown, or another symbol). In Mexico it is called Aguila o Sol (Eagle or Sun). In Peru it is called Cara o Sello ("face or seal", because the other side shows the Great Seal of the State). In Russia it is called Орёл или ре́шка (Oryól ili réshka - eagle or lattice), similar in Poland – orzeł i reszka. In Hong Kong, it is called 公定字 ("Head or word"). In Norway kron denotes the side that shows the kings profile, while mynt is the side that showns the coins value. Swedes use krona eller klave ("crown or hoof"), as old Swedish coinage depicted the regent (or the insignia of the regent) on the obverse (the word "crown" often being used to mean the king), and a highly stylized heraldic shield, reminding people of a hoof, on the reverse. In Israel the game is called Ets o Pally ("tree or Pally").
