Twenty One
You wake up in a velvet-draped casino that seems suspended in a void, run by faceless dealers and watched by an unseen Host. You're told you owe a "debt of existence" and must earn your right to live another day by beating the Quota. You have 5 rounds to meet the quota, or… you're out. Permanently.
