From my own point of view the head or tail game is a high risk guessing between two players on a toss of coin.
Unlike some other casino game, head or tail has to do with total lost or win (its a 50 50 chance) in the sense the player guess the possible outcome of the toss to be either head or tail,and when the guessing comes out correctly the player gets almost double of the stake. The head or tail is an exciting gamble and the player can stake less or more amount
