The Short Version

Sweepstakes casinos run lawfully across the large majority of US states. Four are blacked out: Washington, Nevada and Idaho have been closed for years, and California went dark in January 2026 when AB 831 took effect. Live anywhere else and you are almost certainly clear.

Why Those Four

Washington takes the hardest line on online gaming in the country, with statutes broad enough to catch the promotional model. Nevada protects its licensed commercial casino industry and treats sweeps operators as unlicensed competition. Idaho reads its gambling definitions just as widely. California is the newest, and AB 831 addressed dual-currency sweepstakes gaming head-on rather than incidentally.

Age Requirements

The floor is 18 at most operators, though a number set it at 21, and in some states the higher figure applies regardless of operator preference. Every review notes the requirement for that operator. Age gets confirmed during ID verification, so an inaccurate date of birth at signup surfaces later and can cost you a payout.

The Map Moves

State legislatures have been notably active on this subject through 2026, with committee movement in several states beyond the four already closed. We reconcile availability against operator terms monthly and flag changes on the individual reviews. Even so, the operator terms are authoritative when you sign up, and worth thirty seconds.

Travelling

Eligibility follows your physical location, not your billing address. Operators run geolocation, so logging in from a blacked-out state will restrict play even on an account opened elsewhere. Move permanently to one of the four and you should still be able to withdraw an existing balance, but not keep playing.
