Heads or Tails Online Casino Game

Heads or Tails has been well designed with nothing but simplicity in mind. The game is a fantastic way for beginners to get introduced to betting and perfect for those players that enjoy the thrill of a coin flipping. The graphics are fast moving and show a group of friends sitting in a golf club flipping coins.

A Table Game

This table game is a fifty-fifty odds of a coin spin where players bet on the outcome and the bet range starts from a minimum of 10p per flip and a maximum of £100 therefore a game that will attract both low and high rollers. The game begins with the player clicking the + or – button which sets the amount you wish to bet and just to make sure the player also has to click the confirm button. The player now bets on what they think the outcome will be by clicking on the coin displaying the head or the coin displaying the tail.

Gameplay

Players get to choose whether they flip the coin once by selecting the “flip x 1” button or they can flip two or three times in a row. Each flip has to land on the same side the player has bet on. Landing a single flip rewards the player with 1.9, for two consecutive flips this goes up to 3.8 and for
guessing three flips the prize will be 7.5.

The result of the last six flips are displayed on the left hand side of the screen and players may find that they can reveal a pattern. There is also an option for players to pay double with two sets of coins on the go at the same time. The game reports an RTP of between 93.5% – 95%.

I really enjoyed playing this game, it was a lot of fun and I found that I managed to stay a little ahead in the money stakes too.

Heads Or Tails Game Instructions

Matching pennies is the name for a simple game used in game theory. It is played between two players, Even and Odd. Each player has a penny and must secretly turn the penny to heads or tails. The players then reveal their choices simultaneously. If the pennies match (both heads or both tails), then Even keeps both pennies, so wins one from Odd (+1 for Even, −1 for Odd). If the pennies do not match (one heads and one tails) Odd keeps both pennies, so receives one from Even (−1 for Even, +1 for Odd).

Theory[edit]

Matching Pennies is a zero-sum game because each participant's gain or loss of utility is exactly balanced by the losses or gains of the utility of the other participants. If the participants' total gains are added up and their total losses subtracted, the sum will be zero.

The game can be written in a payoff matrix (pictured right). Each cell of the matrix shows the two players' payoffs, with Even's payoffs listed first.

Matching pennies is used primarily to illustrate the concept of mixed strategies and a mixed strategy Nash equilibrium.^[1]

This game has no pure strategyNash equilibrium since there is no pure strategy (heads or tails) that is a best response to a best response. In other words, there is no pair of pure strategies such that neither player would want to switch if told what the other would do. Instead, the unique Nash equilibrium of this game is in mixed strategies: each player chooses heads or tails with equal probability.^[2] In this way, each player makes the other indifferent between choosing heads or tails, so neither player has an incentive to try another strategy. The best-response functions for mixed strategies are depicted in Figure 1 below:

Figure 1. Best response correspondences for players in the matching pennies game. The leftmost mapping is for the Even player, the middle shows the mapping for the Odd player. The sole Nash equilibrium is shown in the right hand graph. x is a probability of playing heads by Odd player, y is a probability of playing heads by Even. The unique intersection is the only point where the strategy of Even is the best response to the strategy of Odd and vice versa.

When either player plays the equilibrium, everyone's expected payoff is zero.

Varying the payoffs in the matrix can change the equilibrium point. For example, in the table shown on the right, Even has a chance to win 7 if both he and Odd play Heads. To calculate the equilibrium point in this game, note that a player playing a mixed strategy must be indifferent between his two actions (otherwise he would switch to a pure strategy). This gives us two equations:

For the Even player, the expected payoff when playing Heads is ${displaystyle +7cdot x-1cdot (1-x)}$ and when playing Tails ${displaystyle -1cdot x+1cdot (1-x)}$ , and these must be equal, so ${displaystyle x=0.2}$ .
For the Odd player, the expected payoff when playing Heads is ${displaystyle +1cdot y-1cdot (1-y)}$ and when playing Tails ${displaystyle -1cdot y+1cdot (1-y)}$ , and these must be equal, so
