Double Stacks

“Double Stacks” on Netent is a five-reel and three-row video slot game with 10 fixed paylines. The theme is a classic fruit machine: bright colors, traditional fruit symbols such as bell, seven, bar, and diamond, all glowing under neon lights. The game features the “Double Stacks” feature: when every symbol on a reel is the same premium symbol (one of the four highest paying), that reel transforms entirely into a double stack, and all symbols on the reel are counted as two symbols for the calculation of winning combinations. Scatter symbols trigger free spins when at least three land on any reel. During the free spins, you will also see stacked wilds; wild symbols can appear in the winning reel or stacked, enhancing combinations. In free spins, scatters can again award additional free spins: for example, two scatters bring extra spins. Betting options vary so that the game is suitable for a wide range of players. The game does not include a bonus buy feature or a progressive jackpot. Visually and in terms of gameplay, “Double Stacks” combines the style of old-school slot machines with modern fluidity.
