Bob's Full House was a British television quiz show based on the game bingo.
A correct buzz-in allowed that player to light any number on their own middle row, while a miss caused them to become wallied.
If a wallied player was next in line to choose a number, they lost their turn; otherwise, they could not buzz-in on the next question in case of a miss.
The categories were changed out after every player had taken a turn, resulting in new ones being added to the board and/or previously used ones being assigned to different number ranges.
(E.g. a contestant might win a bag of popcorn and an ice cream cone, then be told that they could enjoy these snacks in combination with a dozen movie tickets.)
The player faced an electronic board laid out in the same manner as the cards used in the main game, with one space in each row marked off and numbers from 1 to 60 in the others.
If the player uncovered all the letters, they won a holiday to that destination; if not, they received a small consolation prize.
