Barrel-O-Fun '61 and '62 and Fun Spot '61 and '62 are "Ohio Dime Games" as Jeffrey Lawton calls them in his book "Bally Bingo Pinball Machines".
I've wrapped four games into one episode since Barrel-O-Fun '61 and '62 are the same game (run in different years), and Fun Spot '61 and '62 are the same game as Barrel-O-Fun without the replay button on the front of the game.
These games are six card bingos that do not earn replays.  Instead, they earn 'score' which can be used to play new games... but are not at all replays.
