IGT has added Blake Shelton video slots housed on the CrystalCurve ULTRA gaming machine to its Class III offerings. This low denomination, 40 pay-line game features a jukebox including radio-favorite Blake Shelton songs. During the BS’ers Pick bonus, players select bottle caps to fill spaces on the bingo-style board. If four horizontal or vertical spaces in a line are filled, the player will win the corresponding credit value. If players fill the winning diagonal line, they are awarded one of 100 guitars autographed by Blake Shelton with their jackpot.
