  • North DakotaConditional

    North Dakota sports betting is legal only through tribal casinos — no statewide online/mobile. Wagering is in person under state-tribal compacts; the 2022 compacts also allow mobile wagering within reservation boundaries. Constitution bars most expansion; Jan 2026 HCR 3002 (statewide mobile) failed. Age typically 21 at tribal venues — rules vary by tribal compact, so confirm before wagering.
