Game of skill

A game of skill is a game where the outcome is determined mainly by mental or physical skill, rather than chance.^[2]

Alternatively, a game of chance is one where its outcome is strongly influenced by some randomizing device, such as dice, spinning tops, playing cards, roulette wheels, or numbered balls drawn from a container.

While a game of chance may have some skill element to it, chance generally plays a greater role in determining its outcome. A game of skill may also have elements of chance, but skill plays a greater role in determining its outcome.

Some commonly played games of skill and chance include: poker, collectible card games, contract bridge, backgammon and mahjong.^[3]

Most games of skill also involve a degree of chance, due to natural aspects of the environment, a randomizing device (such as dice, playing cards or a coin flip), or guessing due to incomplete information. For many games where skill is a component alongside chance, such as card games like poker but also some physical games, the skills needed to play the game well include the calculation of mathematical probabilities and the application of game theory. Game theory often leads to tactics such as bluffing and other forms of deception.
