In 1955, Bally experimented with their payout game formula, making an attractive and innovative game called "Crosswords".
Crosswords is an interesting game - you put in coins to light additional puzzles on the backglass (up to four), then play your game - if you spell a word (max of four letters), you win replays. You earn a multiplier-style reward if you also land a ball in one of two specially marked star holes.
It is a very attractive and interesting game, and looks like a lot of fun to play.
