Power Sevens © 1994 WMS Gaming.
A 3-reel mechanical slot featuring Silver and Red 7's and Triple, Double, and Single Bars. During base game play, all pays are normal and the Scroll Top pay table is displayed in the top-box.
When players land two 7 symbols on the pay line, the Power 7's Bonus is triggered. The pay table quickly scrolls to a new Bonus Pay Table offering new winning combinations! The two 7 symbols lock into position and the remaining reel begins to spin. The bonus doesn’t end until the player spins to a winning combination and receives their award. The pay table then scrolls to its original position and normal game play resumes.
