There are usually a number of stepping switches controlling various game features, such as spot number selection, A-B-C-D,turning corners, etc. These units are spasmodically advanced during feature selection (under the control of the spotting disk, the mixers, and the reflex unit) and enable the feature with which they are associated. The lighted teaser arrows on the backglass are also advanced by these units.
Two of the most important stepping units in a bingo are the score (or odds) units and the replay counter(s). Earlier bingos had one each of these units. Later models (those with three color independent odds) had three of each, one score unit and replay counter for each of the three colors; red, yellow, and green.
The score unit(s) is advanced pseudo-randomly during feature selection and control the odds lights on the backglass, which indicate the number of replays a player will receive if he completes a 3-in-line, 4-in-line, or 5-in-line winning combination on the bingo card(s). This unit, in conjunction with the corresponding replay counter, controls the number of replays awarded during payout.
