About the game

Three reels in a 3-4-3 layout and 10 lines. A Bubble lands on the centre reel and inflates: premium symbols stick to it as values, Wilds add to its multiplier. Sooner or later it pops and pays everything it holds, and only the popped cells get fresh symbols. Three Scatters start Bubble Trouble: 8 free spins with one Bubble that lives between spins. The multiplier carries over to the next Bubble, and the giant stage 6 pops for ×50. Bubble Trouble can be bought for 100× the bet.
