1. “Gambling” Meaning
Gambling is:
“risking any money, credit, deposit, or other thing of value for gain contingent in whole or in part upon lot, chance, the operation of a gambling device, or the happening or outcome of an event, including a sporting event, over which the person taking a risk has no control.”
Common examples are poker, blackjack, craps, roulette, and slot machines. Gambling does not include contests of skill, strength, endurance, or speed, such as a
- race,
- sporting competition, or
- carnival games.1
Unlawful gambling is sometimes associated with organized crime and racketeering. The reason the state restrains individuals from participating in these activities is to “safeguard the public against the evils induced by common gamblers and coming gambling houses.”2
What about professional gambling?
Professional gambling is not a term for making a living from, say, playing poker. Instead, it is a term for profiting from unlawful gambling.
Professional gambling means:
- “Aiding or inducing another to engage in gambling, with the intent to derive a profit therefrom; or
- Participating in gambling and having, other than by virtue of skill or luck, a lesser chance of losing or a greater chance of winning than one or more of the other participants.”3
Professional gambling has higher penalties than standard gambling.
What is the social gambling exception?
“Social gambling” – which is lawful – comprises any game, wager, or transaction that is incidental to a bona fide social relationship, participated in by natural persons only, and in which no person is participating in professional gambling.”4
Social gambling may include friends who gather together for a poker night. It may also cover family members who have friendly bets going for who will win the Super Bowl. However, it may not include a poker night that is organized for the purpose of holding a tournament.
A poker game stops being “social gambling” and becomes “professional gambling” if the host takes a “rake” (a percentage of the pot) or charges a “seat fee” to make a profit.
Is gambling allowed for charitable events?
Charitable organizers can lawfully sponsor gaming events at a licensed casino in Colorado. If the charitable organization wants to hold a gaming event outside of the gaming towns, it must ensure the game is not considered illegal gambling.
Charitable gaming events do not qualify under the social gambling exception.
Is internet gambling lawful?
Licensed sports betting is lawful through such platforms as:
Otherwise, according to the Colorado Attorney General and the Limited Gaming Control Commission, internet gambling and telephone sports book betting are unlawful.

Internet gaming is unlawful in Colorado.
2. Penalties
The penalties for participating in unlawful gambling in Colorado depend on the type of activity involved and your criminal history.
Gambling is a petty offense in Colorado, carrying:
- up to 10 days in jail and/or
- up to $300 in fines.5
Meanwhile, professional gambling is a class 2 misdemeanor, with Colorado penalties including:
- up to 120 days in jail and/or
- up to $750 in fines.6
Furthermore, selling, owning, or possessing a gambling device or gambling record is a class 2 misdemeanor in Colorado. Penalties include:
- up to 120 days in jail and/or
- up to $750 in fines.7
In addition to jail time and fines, any gaming devices, records, or proceeds are subject to seizure by police and may be confiscated and destroyed. (Note that you can keep vintage slot machines as long as they are not used for gambling purposes.)8
Finally, unlicensed internet gambling – transmitting gaming information by telephone, telegraph, radio, or other means – is a class 2 misdemeanor carrying up to 120 days in jail and/or $750. You could be charged if you place a bet on your home computer in Colorado, even if the gaming company is based in a place where internet gaming is lawful.9
3. Defenses
In Colorado, gambling generally requires three elements, including:
- consideration,
- chance, and
- a reward.
If any of the elements are not present, the activity may not be considered gambling.
A poker tournament with no fee, buy-in, or payment required from participants is not unlawful. Even if you are participating in a game of chance with prize money awarded to the winners, you did not put up any money to play.
Similarly, a charitable event could include a casino night, provided that money or prizes are not awarded based on the winners. If you are charged a donation or fee to buy in, the charity cannot offer rewards if you win. Prizes could be awarded through a random drawing or raffle, provided the rewards are not directly tied to winning games of chance.

Social gambling is lawful under C.R.S. 18-10-103.

Frequently Asked Questions
What happens if I play poker with friends at my house for money?
Playing poker with friends is legal under Colorado’s “social gambling” exception, as long as it is part of a real social relationship and no one is making a profit from hosting the game.

Regular gambling is a petty offense with up to 10 days in jail and/or a $300 fine. Professional gambling (like organizing games for profit) is more serious – it’s a class 2 misdemeanor with up to 120 days in jail and/or a $750 fine. Police can also seize any gambling equipment and winnings.
What types of gambling are actually lawful in Colorado?
Lawful gambling in Colorado includes the state lottery, licensed sportsbooks (like FanDuel and DraftKings), casinos in Black Hawk, Cripple Creek, and Central City, horse racing events, licensed bingo and raffles for charity, and social gambling among friends where no one profits from hosting.
Can I get in trouble for online gambling from my home computer?
