Having to lose at least 1 ball to progress through the game is certainly not unique to Lady Luck.
Going through my own games... 1950 NASCO BINGO BANGO - you HAVE to lose 2 balls minimum AFTER a certain sequence is made ( B-I-N-G-O B-A-N-G-O). The balls then have to go through both left and right drain lanes.. without accomplishing this.. its impossible to get SPECIAL to light and also extra points award
