We have been playing games of chance for thousands of years.
Long before casinos existed, people were throwing dice, drawing lots, playing games, and making wagers on uncertain outcomes.

Gambling is about creating a set of rules, introducing uncertainty, putting something at stake, and seeing what happens.

The history of gambling is a history of how humans have played with uncertainty and gradually turned it into games, social rituals, economic tools, and, eventually, an industry.
One 2026 study found evidence of games of chance dating back 12,000 years, around 10,000 BCE. Two-sided objects found at Indigenous North American sites may have been used as dice, suggesting that gambling may be substantially older than previously known. [1]
We don't know exactly what the earliest players thought about luck or probability. But we do know that humans were already finding ways to turn uncertainty into something they could play with.

As civilisations developed, games of chance appeared in many different parts of the world.
By the 3rd millennium BCE, cubic dice were already in use in the ancient Near East. Archaeological finds from Mesopotamia include two-, four- and six-sided objects that may have been used to determine movement in board games. [2]
Ancient Greeks and Romans developed rich traditions of dicing. Six-sided dice and four-sided knucklebones were popular both as games in their own right and alongside board games. In Rome, substantial sums could be wagered, and even emperors were known to play, including Claudius. [3] Gaming was a favourite pastime at banquets and other social occasions and dice-throwing cups were sometimes used to make it harder for players to manipulate their throws. [4]
China developed its own rich tradition of games of chance. It also provides one of the earliest documented examples of gambling becoming associated with specialised commercial venues. By the Song dynasty (960–1279), gambling had become increasingly widespread alongside urban and commercial growth, and historical sources describe dedicated gambling establishments in major cities. [5]
People also used chance for purposes beyond entertainment or financial gain.
For thousands of years, humans have used lots and random selection to make decisions when there was no obvious or accepted way to choose between alternatives. Drawing lots could help allocate resources, select people or settle disputes. If everyone agrees to the rules beforehand, a random outcome can sometimes feel fairer than allowing one person to decide.

Randomness can be a way of outsourcing a decision to chance.

In some cultures, random outcomes were also closely connected to divination – using chance as a way of seeking guidance or insight. Research into the history of Chinese gambling, for example, describes connections between gambling, lotteries, and earlier divinatory practices. [6]
Over time, games of chance became increasingly connected to money and commerce.
