Head and Tail
The head and tail game is probably one of the first games you have learned as a child. You may not even have learned it as a game, but rather as a method of making a decision when you are unable to make one. It’s a simple game of coin toss, actually: you get a coin, toss it up into the air, and try to guess if what comes face-up is the head side of the coin, or the back side, called the tail. If you guess right, you win the game.
This is one of the fastest ways to win (and, subsequently, lose) money because of the 50-50 chances of winning. Of course, this figure of probability only applies to a coin that has been checked for fairness. For those casual players, a regular currency coin works enough for the game, but the chances may not be 50-50 at all because of the irregularities in weight distribution when the coin was made. Having this imbalanced weight distribution may cause the coin to fall a certain way more times than it will fall the other way when it is tested for fairness. Those who offer it as a betting game, then, use a coin that has been manufactured to ensure a fair chance for the players to win – the coin’s weight is controlled so that there truly is a 50-50 chance of winning, and the discrepancies are limited to a minimum.
At the end of the game, the person who guesses right gets to win 200% of the money he bet on his choice, with an average of a 5% deduction (depending on the establishment) for the house. The one who loses only loses the money that he bet on that particular round. It’s quick and it’s easy but as mentioned earlier, be careful – it’s one of the fastest ways to win and lose money.
