Strictest vs most lenient states for sports betting

Side-by-side: which states impose the heaviest sports betting rules and which are friendliest, with the specific signals that separate them.

Side-by-Side Comparison

State	Strict / Lenient	Key Signals
Utah	Strictest	Constitutional ban (Utah Const. art. VI, § 27); criminal penalties for all forms including offshore and DFS; no lottery, no tribal carve-out
South Carolina	Strictest	Dual statutory + constitutional prohibition (S.C. Code Ann. § 16-19-10 + S.C. Const. Art. XVII, § 7); voter-approved constitutional amendment required before any bill can pass
Mississippi	Strict	Legal but retail-only, casino floor only; three mobile bills died in 2026 session; no path to statewide mobile
New Hampshire	Most Lenient	Minimum age 18 (2025 bill to raise it to 21 defeated 215–140); mobile-only, no in-person registration required; regulated by Lottery Commission under RSA 287-I
Kentucky	Most Lenient	Minimum age 18, lowest threshold among active markets; retail and mobile both legal since September 2023; regulated by KHRGC
Colorado	Most Lenient	No in-person registration required; fully legal online statewide since May 2020; governed by C.R.S. § 44-30-1501 through § 44-30-1516 with no residency requirement

What Makes a State Strict

Three structural patterns separate the restrictive states from the rest.

Constitutional prohibition with criminal exposure

Utah is the clearest case. The ban on gambling is written directly into the state constitution (Utah Const. art. VI, § 27), which means no legislative majority can undo it. Changing the law requires a two-thirds supermajority in both chambers followed by a statewide referendum — a threshold that has never come close to being met. Crucially, the prohibition is not limited to licensed sportsbooks. Offshore sites, private pools, and daily fantasy sports all carry criminal penalties under Utah law. DraftKings and FanDuel geo-block Utah residents entirely. There is no social gambling carve-out, no tribal gaming, no lottery. Utah and Hawaii are the only two states maintaining a blanket prohibition on virtually all gambling.

Dual-layer statutory and constitutional barriers

South Carolina adds a second lock on top of the first. The general gambling statute (S.C. Code Ann. § 16-19-10) criminalizes wagering at the statutory level, while S.C. Const. Article XVII, Section 7 bans lotteries and most gambling at the constitutional level. That two-tiered structure means even a simple legislative majority passing a sports betting bill would be immediately unconstitutional. Legalization requires a constitutional amendment approved by voters — a process that has not yet produced a qualifying ballot measure. Offshore sites are not a legal workaround; using one while physically in South Carolina carries potential liability under the same statute.

Retail-only carve-outs that freeze the market

Mississippi represents a different kind of strictness: legal in name but severely restricted in practice. Sports betting has been legal since August 2018, but only on a casino floor. You must be physically inside a licensed land-based casino to place a wager. There is no statewide mobile app, no remote registration, and no online option. Three separate mobile betting bills were introduced in the 2026 legislative session and all three died in committee without a floor vote. The in-person-only rule is not changing in the near term. This structure effectively excludes the majority of potential bettors who have no casino nearby and limits the market to a fraction of what neighboring states generate.

Montana fits a related pattern: legal, but restricted to a single state-run app (SportsBet Montana) that can only be used while physically inside a licensed retailer — a bar or casino holding a qualifying lottery license. Private operators like DraftKings and FanDuel are entirely excluded under the Montana Sports Wagering Act (MCA § 23-5-802 et seq.).

What Makes a State Lenient

The most permissive states share three traits: low or moderate age thresholds, no in-person registration requirements, and broad mobile access without structural gatekeeping.

Age thresholds below the 21-plus standard

New Hampshire and Kentucky both set the minimum betting age at 18, the lowest threshold among active legal markets. In New Hampshire, the 18-plus floor is not an oversight — it was actively defended. A 2025 bill to raise the minimum age to 21 was defeated by a 215–140 House vote on February 6, 2025, signaling deliberate legislative intent to keep the market accessible. Kentucky's 18-plus threshold aligns with its historical pari-mutuel wagering rules for horse racing and has carried over into the sports betting framework administered by the Kentucky Horse Racing and Gaming Corporation (KHRGC). Most states that have legalized sports betting set the floor at 21, making these two outliers meaningfully more permissive on access.

No in-person registration and full remote onboarding

Colorado and Illinois both eliminated the in-person registration requirement that once forced bettors to visit a physical casino before using a mobile app. Colorado has never required it: since the market launched on May 1, 2020, under HB 19-1327 and C.R.S. § 44-30-1501 through § 44-30-1516, bettors have been able to download an app, verify identity remotely, and place a wager without visiting a casino. Illinois permanently allows remote registration as well, meaning the full onboarding process happens online. Compare this to Nevada, which still requires a one-time in-person account registration at a licensed Nevada property before mobile wagering is permitted — a meaningful friction point that Colorado and Illinois have removed entirely.

Mobile-first design with no residency requirement

New Hampshire's entire legal market is mobile-only. There are no brick-and-mortar sportsbook casinos in the state. All wagering occurs through licensed apps regulated by the NH Lottery Commission under RSA 287-I. The absence of retail infrastructure is not a limitation — it reflects a deliberate choice to build a low-overhead, app-first market. No residency requirement exists; physical presence within state lines is all that is required. Colorado similarly imposes no residency requirement, only a geolocation check confirming the bettor is physically inside state lines at the time of the wager. Both states contrast sharply with the retail-only models in Mississippi, South Dakota (Deadwood only), and Delaware, where the absence of mobile access is the binding constraint on market participation.

Frequently Asked Questions

Why is sports betting illegal in Utah?

Utah has a constitutional ban on all forms of gambling, including sports betting, which is enshrined in the state constitution. This prohibition requires a two-thirds supermajority in both legislative chambers and a statewide referendum to change, making it extremely difficult to legalize.

What law governs sports betting in South Carolina?

In South Carolina, both a statutory prohibition (S.C. Code Ann. § 16-19-10) and a constitutional ban (S.C. Const. Art. XVII, § 7) exist, effectively criminalizing sports betting. Legalization would require a constitutional amendment approved by voters.

Are there any active legislative proposals for sports betting in South Carolina?

As of now, there have been no successful proposals for sports betting in South Carolina, as any bill would need to overcome the dual-layer statutory and constitutional barriers.

How does the sports betting landscape in Mississippi compare to neighboring states?

Mississippi allows sports betting but only in retail settings on casino floors, which limits access compared to neighboring states like Louisiana and Tennessee, where mobile betting is available.

What do residents in Utah and South Carolina do given the absence of legal sports betting?

Residents often turn to illegal offshore betting sites or engage in informal betting pools, despite the risks of criminal penalties associated with such activities.
