Colorado has had legal online sports betting since 2020, but online casinos are not legal, and the state constitution ties casino gaming to three historic mining towns, so adding it online would take a statewide vote. Real-money online casino play from Colorado happens offshore. We verified which offshore casinos take Colorado players, noted that Bovada refuses the state, and ranked the rest.
Facts checked against Colorado law and casino terms: 24 July 2026
You have sportsbooks. You do not have casino apps.
Colorado bettors have had the apps since May 2020, when the sportsbooks went live after voters narrowly passed Proposition DD the previous November. DraftKings, FanDuel, BetMGM and a long list of others compete hard here. But open the casino tab inside one of those apps from a Colorado location and it is switched off, because the state legalized online sports betting and nothing else online.
Casino gaming in Colorado is legal only in a very specific sense. When voters approved it in 1990, they tied it to three old mining towns, Black Hawk, Central City and Cripple Creek, plus two tribal casinos in the southwest corner. That limit is written into the state constitution (Article XVIII), which is why an online-casino law is not just a bill away: expanding casino gaming beyond those towns would take a statewide vote, not a simple act of the legislature.
So a Colorado player who wants real-money slots or online blackjack has the licensed sportsbooks closed to them on the casino side, the physical casinos an hour or more up a mountain road, and the offshore casinos below as the online fallback.

Best online casinos that accept Colorado players
Ranked by our review scores. The green line under each casino is our eligibility check: the date we read that casino’s own terms and confirmed Colorado players are welcome. One casino is still waiting on its check, so its card makes no promise yet.
Colorado regulates sportsbooks but not online casinos, so there is no state-licensed casino app to recommend. The casinos above are offshore: they run from outside the US, mostly under Curacao or Panama licenses, and they take Colorado players because no Colorado regulator reaches them.
That comes with a real trade-off, and we would rather name it than bury it. If an offshore casino treats you badly, no Colorado agency will step in. The operator’s own record is your protection, which is why payout history and dispute handling weigh so heavily in our reviews, and why we run a complaints desk on every review page and take unresolved cases up with the casino ourselves.
One familiar name is missing on purpose. Bovada, usually our top US pick, refuses Colorado: the state sits on its published restricted list, so it does not appear above. That is the kind of thing we verify rather than assume. For the wider picture of who licenses these sites and which licenses mean something, read our offshore casino guide.
How we check these casinos for Colorado
Every offshore casino publishes a list of US states it refuses, and no two lists are the same. Bovada blocks twenty states, Colorado among them; BetOnline blocks exactly one; Red Dog blocks only Kansas and Michigan. So we check each casino against its own terms:
Read the terms. We open each casino’s current terms and conditions, find its restricted-states list, and check whether Colorado is on it. Bovada is, which is why it is not in the list above.
Date the check. The green line on each card is the day we last read those terms. These lists change, usually after a regulator sends warning letters, so we re-read them when rankings move.
Say so when we haven’t. A casino with no completed check carries no eligibility line. Right now that is VipSlots: still ranked on review strength, but making no Colorado promise until we have read its terms.
Gambling law in Colorado: what is actually legal
Colorado allows casinos in three towns, a pair of tribal casinos and the country’s busiest field of sportsbooks, but online casino play is not among the things the state permits.

Status
The facts
Online casinos
Illegal
No legal online casino. Colorado authorizes online sports betting and land-based casinos in three historic mining towns, but casino gaming is boxed in by the state constitution (Article XVIII), which permits it only in those towns and on tribal land, so an online-casino expansion would need a statewide vote.
Land-based casinos
Legal
Legal, but only in three places. Voters approved limited-stakes casino gaming in 1990 for the historic mining towns of Black Hawk, Central City and Cripple Creek, plus two tribal casinos in the southwest; a 2020 measure (Amendment 77) let those towns set their own bet limits.
Sports betting
Legal
Legal and live since May 2020, after voters narrowly approved Proposition DD in November 2019. Online and retail books are regulated by the Colorado Division of Gaming, with tax revenue directed largely to the state water plan.
Lottery
Legal
The Colorado Lottery has run since 1983; draw games and scratch tickets are sold in person.
Daily fantasy sports
Legal
Daily fantasy sports is legal and regulated; Colorado passed a licensing law in 2016 and moved oversight to the Division of Gaming.
Sweepstakes casinos
Gray area
Unsettled. No Colorado statute names the dual-currency sweepstakes model, the Division of Gaming has not issued public cease-and-desist letters against it, and no ban bill has advanced, so the category sits in a gray area even as neighboring states move against it.
Charitable bingo & raffles
Legal
Bingo and raffles run by qualified nonprofits are licensed by the Secretary of State under the state's Bingo-Raffle law.
Will you get in trouble for playing online from Colorado?
Placing a bet is a class 1 petty offense under C.R.S. 18-10-103, carrying a fine up to $300 and up to ten days in jail. The same statute treats making a living from gambling more seriously, as professional gambling (a misdemeanor). Professional gambling, meaning running or profiting from a gambling operation, is a class 2 misdemeanor under C.R.S. 18-10-103, with repeat offenders facing enhanced penalties. Enforcement by the Colorado Division of Gaming targets unlicensed operators and machines; there is no record of Colorado prosecuting an individual for playing at an offshore online casino. Federal law is aimed at gambling businesses and payment processors, not players.
Colorado has legalized gambling in careful, voter-approved steps, and each one has drawn a tight boundary around what comes next.
1990
Voters approve limited-stakes casino gaming, but only in Black Hawk, Central City and Cripple Creek. The three-towns model is written into the constitution.
2019
Proposition DD passes by a razor-thin margin, legalizing sports betting and steering the tax toward the state water plan.
2020
Sports betting goes live in May across online apps and the casino sportsbooks. Online casino games are not part of it.
2020
Voters pass Amendment 77, letting the three towns raise or drop their own bet limits and add games. Casino gaming stays inside those towns.
2026
No online-casino bill has moved. Because the constitution ties casino gaming to the three towns, adding it online would take another statewide vote.
Taxes on winnings in Colorado
Offshore casinos send no tax forms, but that does not make winnings invisible. The IRS counts all gambling winnings as taxable income whether or not a W-2G exists (IRS Topic 419), and Colorado adds its flat 4.4% state income tax on top (Colorado Department of Revenue). The rate is the same for everyone, though in strong revenue years the state’s TABOR rules occasionally trim it a notch at filing time.
Losses used to offset winnings fully if you itemized. From the 2026 tax year that changed: under the One Big Beautiful Bill Act, only 90% of gambling losses are deductible federally, still capped at your winnings. Win $10,000 and lose $10,000 in the same year and you broke even but still owe federal tax on $1,000.
The practical takeaway: keep session-level records. Dates, deposits, withdrawals, results. With no casino paperwork coming, your own log is the paper trail you will have.
Getting money in and out from Colorado
No Colorado law stops a deposit. The friction is your bank: an issuing bank can decline a gambling charge, which is routine and not a legal problem. Visa clears more often than Mastercard, and several of these casinos add 5 to 15% fees on card deposits. Cards also cannot receive a withdrawal.
Crypto is what these casinos are built around and the only method good in both directions. Bitcoin deposits are free at most of them, and payouts run in minutes to hours: 2 to 6 hours at Ignition, about 15 minutes at Slots.lv once the standard 48-hour approval clears, inside a day at Cafe Casino. New to crypto? Our Bitcoin buying guide walks it through.
Courier checks remain an option for the crypto-averse and still take one to two weeks. Our banking hub compares every method, and each review’s banking section lists the fees we measured.
Colorado online casino FAQ
If sports betting is legal in Colorado, why are casino apps not?
Because Proposition DD legalized online sports betting only. It did not touch casino games. And Colorado’s constitution ties casino gaming to Black Hawk, Central City and Cripple Creek, so putting it online would need a statewide vote, not just a bill.
Can I play at Black Hawk or Cripple Creek casinos online?
No. Those casinos are licensed to operate in their towns, not over the internet. They can take your sports bet through an app because sports betting is separately legal, but their slots and tables are in-person only.
Why is Bovada not on your Colorado list?
Bovada refuses Colorado. The state is on Bovada’s own published restricted-states list, so it will not open an account for a Colorado player. That is why our top pick here is Ignition instead.
Do I owe taxes on offshore casino winnings in Colorado?
Yes. Colorado taxes winnings at its flat 4.4% income tax rate, and federal tax applies on top. From the 2026 tax year only 90% of gambling losses are deductible federally. Details in the taxes section above.
What is the minimum gambling age for Colorado players at offshore casinos?
18 at most offshore casinos, though a few require 21. Colorado’s casinos and sportsbooks are 21. Each casino’s terms state its own minimum, so check before you deposit.
