A major change to the spell name feature. In previous games, you had to hit a couple holes to light letters in the game name. If you lit the right letters, you'd get a score in that game.

In Nevada, the holes now light the next letter in the game name, and more importantly, the name lights don't reset at the start of the next game. In effect, the machine builds a bonus over a number of games. This was similar in concept to a feature found in Bally one-ball games, but Bally never used it in bingos.

I suppose this created bingo "vultures" - people who hovered around waiting for the name to be almost complete, then they play the machine. 45 years later, the newer slot machines also have these bonus games that work in a similar fashion, and the vultures are back!

one-card games

The game has one main card, usually a 5x5 grid of numbers.

Usually, at least three numbers next to each other on either a horizontal, vertical, or the main 5 number diagonals are required to win.

There were, however, a few variations that occured over the years. The dimensions of the card, 2-in-line winners, and winning on the other diagonal combinations were all features that were used.

Another common feature was corners scoring.
