Slotastic! has announced a special deposit bonus to celebrate its launch of the new five-reel Bubble Bubble 2 video slot from developer RealTime Gaming.Due to be available until the end of the month, the 113 percent deposit bonus also includes 33 complimentary spins on Bubble Bubble 2 and can be obtained by entering the coupon code ‘BUBBLESEQUEL’.Slotastic! described Bubble Bubble 2 as ‘the long-awaited sequel’ to RealTime Gaming’s Bubble Bubble predecessor that features a pair of ‘sexy wand-waving witches’ as well as a trio of bonus games that have been designed to ‘increase winnings and playtime’.“The voluptuous Winni Witch introduced in the original Bubble Bubble slot is back in this sequel,” read a statement from Slotastic!.“This time she’s joined by her equally beautiful and bewitching sister Wanda. Both are expanding wild symbols that cover all three rows of any reel they appear on to magically create more chances for winning combinations. The sisters only appear on reels one and five and, since they’re expanding wilds, they stretch to cover the whole reel when they do. If they both appear in the same winning combination, they multiply the win by nine times.”Players can trigger one of the three bonus games featured in Bubble Bubble 2 by collecting a trio of magic wand scatter symbols. The first of these, Greater Ghosts, offers up to 20 free spins with additional wilds while seven free spins containing a minimum of one expanded wild awaits in the Ultra Bewitched bonus. There are also nine bonus spins with witches turning the middle reel wild and conjuring 33 extra free games in the Wilder Witches bonus game.
