Drop & Lock™ is the next evolution of the hugely successful Lock It Link® series, adding a breathtaking drop to the already exhilarating Lock It Link mechanic! During the new Drop & Lock Feature, symbols displaying credit prizes and jackpots drop to the bottom of the display, and once a full row is achieved, drop off the reels awarding the sum of the row’s displayed prizes. Sweet Tweet™ is one of the first themes in this thrilling new series and includes a Free Game Bonus where Bird symbols that land on the reels expand making the whole reel Wild, increasing the chance of a big win!
