The casino is smoke-free. The Real Time Rewards loyalty program (Penn Entertainment) serves regular guests. The minimum gambling age is 21, regulated by the Illinois Gaming Board. Phone: (800) 426-2537; website: argosyalton.com.

Alton is in Madison County in southwestern Illinois on the Mississippi River, approximately 20 miles north of downtown St. Louis, Missouri via IL-255 and I-270. The Piasa Street address sits on the Alton waterfront along the Mississippi — a riverfront that holds historical significance as the site of the last Abraham Lincoln–Stephen Douglas debate in 1858 and as a major point on the Underground Railroad. The Argosy name references the mythological Argo, the ship of Jason and the Argonauts, consistent with the nautical and riverboat branding common among Illinois riverboat casino operators in the early 1990s.

Argosy Casino Alton was one of the first ten casinos licensed under the Illinois Riverboat Gambling Act of 1990 — legislation that required casinos to operate on riverboats on navigable waterways, a requirement that was modified over time to allow dockside operation. The casino serves the St. Louis metropolitan area from the Illinois side of the river, drawing from eastern Missouri and southwestern Illinois.

Smoke-Free Gaming and Table Games

Argosy Casino Alton is smoke-free — a confirmed differentiator in the Illinois riverboat casino market where many properties permit smoking on the gaming floor. The casino runs 1,008 slot machines and 14 table game positions including 21+3, 3 Card Poker, Blackjack, Craps, Mississippi Stud, Roulette, and Video Poker.

Mississippi Stud is a five-card progressive community card game in which players make additional bets after seeing two hole cards and three community cards, paying on pairs of jacks or better with escalating payouts for stronger hands. 21+3 is a Blackjack side bet evaluating the player’s first two cards plus the dealer’s upcard as a three-card poker hand, paying on flushes, straights, three of a kind, and straight flushes.
