Key West is the first bingo that Bally produced that allowed you to collect wins in triple deck scoring before you were locked out of the moving numbers feature (in this case, Magic Squares).
Collecting in multiple colors is a great thrill.
The ballyhole returns - awarding first extra ball, corners score green 5-in-a-line, and also a first for this game, you can swap the red and yellow scores if one or the other is higher and you want to earn those extra replays!
