Forty casinos operate in Colorado, and none of them will deal a card or spin a slot for anyone under 21. Table games, card games, poker and slot machines all carry that age limit under state law.

State-based gambling sites and unlicensed offshore operators are excluded from that. For a real casino floor at 18, the answer lies outside Colorado in the states in the US that offer 18+ casinos.
