In Quick Play mode, you access all games in unlocked casinos, playing as a randomly selected game character. There are no goals or challenges here. Poker Tournaments give you instant access to tournaments available in Adventure and Quick Play modes, but Adventure has more table limits.
The game features four different casinos with their own games, house rules, and table limits. You start with $1000 at the Hard Rock Casino. The goal is to win lots of money and earn a high enough reputation to play in invitation-only tournaments and high-stakes games. Your objective is to become the "Hard Rock High Roller".
