What to Know Before Visiting

Ameristar St. Charles supports a mix of No-Limit Hold'em, Limit Hold'em, Omaha, and other games depending on player demand. The $1/$2 and $2/$3 No-Limit Hold'em games are among the room's more consistently listed options, while higher limits and Omaha formats may be less predictable.

Players should call ahead when traveling for a specific game, particularly during off-peak hours. The room's phone reservation system allows players to put their name on a waiting list up to one hour before arrival.

Tournament players should also distinguish between the room's regular cash-game operation and special tournament festivals. Major series such as MSPT have their own schedules, structures, and registration details that should be checked separately.
