Will It Ring™? Bonus Booster is a 5-reel, 3-row, 15-payline slot from S Gaming, full of retro vibes, Sticky Wilds, and three unique Phone Bonuses that can boost your play. Land the Red Phone to trigger Wild Drop Spins, awarding 9 spins with Sticky Wilds locked in place. The Yellow Phone launches Box Breaker, giving 5 spins to smash boxes and reveal prizes. The Blue Phone activates Pick-A-Box Mystery, where 15 mystery boxes hide multipliers up to x45 and even Jackpot symbols. When the Bonus Booster is triggered, free spins are doubled, and you get an extra chance to pick a mystery box. When two phones ring together, a ‘conference call’ Bonus activates, combining Sticky Wilds and multipliers for maximum reward potential. With Minor, Major, and Mega jackpots up to 500×, every spin could trigger the bonus you’ve been waiting for. 
Answer the call and see which bonus you could pick up.
