Game of chance
A game of chance is an activity in which the outcome is determined primarily by random factors, such as dice rolls, card draws, or wheel spins, rather than participants' skill or strategy.[1] These games differ from games of skill, where player expertise and decision-making substantially affect results, though many real-world contests blend elements of both, with legal and regulatory distinctions often hinging on the predominance of chance.[2][3] Common examples include roulette, slot machines, lotteries, and simple dice games, all of which rely on probabilistic mechanisms to resolve uncertainty.[4] In mathematics and probability theory, games of chance provide foundational models for understanding random variables, expected values, and long-term averages, enabling calculations of odds and house advantages in gambling contexts.[5][6] While they underpin recreational and commercial gambling industries, their classification influences regulatory frameworks, with pure chance games typically subject to stricter controls to mitigate risks of addiction and financial loss.[7][8]
