The Three-Town Geography

Three Mountain Towns, All Thirty-Three Casinos.

Every commercial casino in Colorado sits inside one of three former mining towns: Black Hawk and Central City in Gilpin County, Cripple Creek in Teller County. The Limited Gaming Act, written in 1991, still bars commercial gaming anywhere else in the state. That geography is why a sportsbook app you open in Denver has to be tethered to a property an hour up the canyon.

Bet caps through three statewide amendments

  1. Effective

    $5 max bet

    Limited Gaming Act takes effect. Slots, blackjack, and poker only. Hours capped at 8 a.m. to 2 a.m. Amendment 4 authorized it the prior November on a 57.3 to 42.7 vote.

  2. Effective

    $100 max bet

    Amendment 50 raises the cap to $100, adds craps and roulette, and allows 24-hour operations. Local votes followed in all three towns the prior November.

  3. Effective

    No state cap

    Amendment 77 hands the cap question to the three towns themselves on a 57.3 to 42.7 statewide vote. Black Hawk 2A passed 50 to 11, Central City 2B 219 to 78, Cripple Creek 2A 266 to 97. All three lifted the cap.

Regulatory Timeline

How It Happened

  1. Proposition DD legalizes sports betting

    Voters approve Proposition DD 50.7% to 49.3%, authorizing a 10% tax on sports betting proceeds with revenue dedicated to the Water Plan Implementation Cash Fund.

  2. Mobile sports betting market launches

    The Division of Gaming launches the regulated online sportsbook market with each licensed casino entitled to one online skin. The list later grows past 20 active apps including DraftKings, FanDuel, and BetMGM.

  3. Amendment 77 removes the $100 bet cap

    Statewide voters approve Amendment 77 by 57.31% to 42.69%, removing the constitutional limit on single bets and game types. Local councils in Black Hawk, Central City, and Cripple Creek raise limits effective May 1, 2021.

  4. Department of Revenue floats iGaming talks

    DOR Executive Director Mark Ferrandino tells a National Conference of State Legislatures panel in Denver that conversations about legalizing online casino games have started. No bill follows in the 2024 or 2025 sessions.

  5. Black Hawk joins anti-iGaming coalition

    The Black Hawk City Council votes to become the first US municipality to join the National Association Against iGaming, a coalition organized by Monarch Casino and other land-based operators.

Where the Sports Tax Goes

$33 Million for Water, Out of $6.3 Billion in Bets.

Proposition DD wrote the destination right into the statute. After Division of Gaming admin costs, a 6 percent hold-harmless slice for the existing casino towns, and a small problem-gambling line, the rest of the 10 percent sports betting tax flows to the State Water Plan. Colorado is the only state in the country that has tied the bulk of its sports betting revenue to water conservation.

The water angle matters to the iGaming conversation because it gives a reform a built-in funding pitch. A state water plan with a $39 million pipeline this fiscal year and 440 funded projects across 57 of 64 counties already has its constituency. Any future online casino bill would either feed the same fund or have to justify competing for it.

The Law

Why There Are No Online Casinos

Colorado's casino law lives in CRS Title 44 Article 30, the Colorado Limited Gaming Act, and it authorizes commercial gaming only inside the historic districts of Black Hawk, Central City, and Cripple Creek. The Colorado Limited Gaming Control Commission writes the rules and the Division of Gaming inside the Department of Revenue runs licensing and enforcement. Voters added sports betting in 2019 with Proposition DD, which passed by about 1.3 percentage points, and the mobile market launched on May 1, 2020 with each retail casino entitled to one online skin. Amendment 77 followed in November 2020, when 57% of voters removed the constitutional $100 bet cap and gave the three gaming towns power to set their own limits and game menus starting May 1, 2021. None of that touched online casino games.

Real-money online slots and table games remain outside the statute. Department of Revenue Executive Director Mark Ferrandino floated iGaming talks at a National Conference of State Legislatures panel in July 2023, but no legislator has introduced an online casino bill in the 2024, 2025, or 2026 sessions. The legislative focus this year has stayed on the existing sports betting market. Governor Polis signed HB25-1311 on May 15, 2025, phasing out the free-bet tax deduction by July 1, 2026, and SB26-163 folds racing oversight into the Limited Gaming Control Commission and adds sports betting to the state's self-exclusion program. Opposition has organized too. Black Hawk became the first US city to join the National Association Against iGaming in March 2025, and Central City followed shortly after.

The Opposition Coalition

Four NAAiG Members, All Within an Hour of Denver.

The National Association Against iGaming launched in November 2024. Within five months, every Colorado jurisdiction with a commercial casino had joined. No other state has anything close to that density of opposition built in at the local-government level. The Monarch Casino tie is the structural reason. Vice chairman Jason Gumer is Monarch's general counsel, and Monarch's flagship property sits in Black Hawk.

The smallest of the three gaming towns rounds out the Colorado bloc inside NAAiG.

Projected Colorado jobs lost

$520MTotal output across direct, indirect, and induced spending.
Problem-gambling cost
$830MEstimated social cost from increased addiction, debt, and related harms.

The numbers come from an Innovation Group study commissioned by NAAiG. iGaming supporters argue the model overweights cannibalization and underweights new players who never travel to Black Hawk in the first place. Either way, the political fact is that Colorado has no MGM or Caesars holding a commercial license here, so the legalization side has no in-state operator with capital to spend on the other half of the argument.

Tax Rate Context

New York Charges 51 Percent. Colorado Charges Ten.

Proposition DD set the Colorado sports betting tax at 10 percent of net proceeds in 2019. TABOR keeps it there. The voter-approved rate cannot move higher without a new statewide ballot question, which is why the legislature has had to chase revenue through the free-bet deduction instead of the headline number. The rest of the country runs in a much wider band.

Sports-betting tax rates across the major mobile-handle states, ranked from highest to lowest.
StateRateBasis
New York51%GGR, mobile
Pennsylvania36%GGR, online and retail
Illinois20-40%GGR, graduated
Ohio20%GGR, mobile and retail

New Jersey19.75%GGR, mobile and retail

Colorado10%Net proceeds, mobile and retail
Indiana9.5%GGR, mobile and retail
Michigan8.4%Adjusted gross sports betting receipts
Iowa6.75%Net receipts
Tennessee1.85%On handle, not revenue

The low rate is the reason Colorado attracted twenty-plus sportsbooks under its one-skin-per-casino structure, and the reason operators fought the HB25-1311 deduction phase-out so hard. The deduction was the only lever that could pull the effective rate below 10 percent. Without it, the headline rate and the effective rate finally match the voter-approved figure starting July 2026.

Three Bills in Twelve Months

The Consumer Protection Lab Other States Are Watching.

While the iGaming conversation stays parked, Colorado has spent the last twelve months passing the most aggressive consumer protection package any sports betting state has tried. Each bill sets a national first. If Governor Polis signs SB26-131, Colorado becomes the first state to cap daily deposits, ban operator push notifications, and bar sportsbooks from cutting off winning bettors absent documented misconduct.

  1. HB25-1311

    Free-bet deduction phase-out

    Phases the sports betting free-bet tax deduction from 2.25 percent of net proceeds down to 1 percent on January 1, 2026, then to zero by July 1, 2026. Pushes the effective tax rate back toward the voter-approved 10 percent.

  2. SB26-131

    Six-deposit cap, no credit cards, no push notifications

    Caps sports betting deposits at six per day per account. Bans credit card funding outright. Bans operator push notifications and text messages that encourage bets or deposits. Bars sportsbooks from restricting winning bettors absent documented misconduct.

  3. SB26-163

    Self-exclusion in statute, racing folded in

    Codifies the Division of Gaming self-exclusion program for sports betting into state law. Repeals the Colorado Racing Commission and folds racing oversight into the Limited Gaming Control Commission. Adds two seats to the commission.

Two things are true at the same time in Denver. The legislature will not move on iGaming. The legislature will move aggressively on how the existing sports betting market treats its customers. The industry that lobbied hard against HB25-1311 and SB26-131 is the same industry that would lobby for an iGaming bill. That dynamic is part of why no bill has been introduced.

FAQ

Colorado Gambling FAQ

Are online casinos legal in Colorado?

No. Colorado has not legalized real-money online slots or table games, and no operator is licensed by the Limited Gaming Control Commission to offer them. Any site advertising a Colorado online casino with real money is offshore and unregulated.

Can I legally bet on sports online in Colorado?

Yes. Online sports betting has been legal since May 1, 2020, when the market launched under Proposition DD. More than 20 mobile sportsbooks operate here, each tied to a casino license in Black Hawk, Central City, or Cripple Creek. The minimum age is 21.

Where are Colorado's commercial casinos?

All 33 commercial casinos sit inside the historic districts of three mountain towns: 18 in Black Hawk, 11 in Cripple Creek, and 4 in Central City. Voters legalized gambling in these towns in 1991, and Amendment 77 removed the $100 single-bet cap effective May 2021.

Are tribal casinos open in Colorado?

Yes. Ute Mountain Casino Hotel near Towaoc opened in September 1992, and Sky Ute Casino Resort near Ignacio opened in September 1993. Both are Class III operations under tribal-state compacts and offer slots, blackjack, poker, craps, roulette, and live keno.

Are sweepstakes casinos allowed in Colorado?

Colorado has no statute banning sweepstakes or social casinos, so sites with dual-currency prize redemption are generally accessible to residents. They are not licensed casino gambling, and prize rules depend on the operator. No Colorado ban has been introduced through May 2026.

Can I buy lottery tickets online in Colorado?

Not directly from the Colorado Lottery. Licensed couriers like Jackpocket and Lotto.com take online orders for players physically in Colorado and deliver scanned tickets, with $38 million in courier sales in fiscal 2025. SB26-117, signed in 2026, bans credit-card payment for lottery products but kept courier sales legal.

How old do you have to be to gamble in Colorado?

Twenty-one for casino games and sports betting, online or in person. Eighteen for the state lottery, charitable bingo, and parimutuel betting. Tribal casinos enforce the 21-and-up rule under their compacts.

Will Colorado legalize online casinos?

There is no iGaming bill in front of the legislature as of May 2026. The Department of Revenue floated talks in 2023, but no bill followed, and Black Hawk and Central City have publicly joined a national coalition opposing online casino expansion. We update this page when the legal status changes.
