An immersive gaming facility has a plurality of game rooms, each with a respective interactive gaming space with electronically controlled interactive game elements, a respective entrance through which participants are admissible from a waiting area with a respective sign-in station operable to control admission of participants in a groupwise fashion. After admission, an executed game session involves controlled operation of the interactive game elements and monitoring of participant interaction therewith to identify participant completion or failure of tasks in said game session; and terminate execution of said game session upon expiry of a time limit or multiple detected failures exceeding a predetermined limit. The waiting areas are accessible independently of one another off a shared common area, allowing participation among the game rooms in any participant-selected order. The gaming spaces are darkened environments illuminated only by the interactive game elements and game status displays.
