Double Stacks Slot

While NetEnt is one of the most famous game developers on the planet, they have come under fire over the years for developing lightweight slots with limited variance and potential. There is an excessive amount of Starburst and an insufficient amount of Dead or Alive.

Of course, there are exceptions to every rule, but we prefer our games to pack a punch and deliver some genuine thrills. And that means anything with a reasonable payoff. That is why news of NetEnt’s latest release, Double Stacks, has us intrigued.

Fans of Twin Spin and the current BerryBurst will adore Double Stacks’ vibrant colours and retro fruit machine ambience. However, the wild stacks and the free spins round are more thrilling since they can result in big prizes. There are over 30 play options available, each featuring stacked wilds on the reels.

It appears and sounds sharp, and it possesses promise. Therefore, let us learn more!

About Double Stacks Slot Game

After loading the slot, players are greeted by a simple yet incredibly focused vintage game window in dark hues. NetEnt games are known for their crisp graphics and fluid animations. A lovely percussion soundtrack is interspersed with the expected win and teaser sounds. The average pay for each of the primary symbols is shown in four windows above the game grid.

With the pay symbols, the classic motif is maintained. Non-stacked melons, lemons, plums, and cherries are listed in ascending order of value. Bells, the Bar, sevens, and diamonds are the four primary symbols that can appear stacked. The wild character is a gold star with the word “Wild” across it, and it acts as a substitute for all other symbols except scatters. Only during the free spins feature does it seem stacked. The bonus sign is a glistening circle in brilliant colours with the word “scatter” inscribed. Three or more are often required to trigger the free spins bonus.

The double-stacked pay symbols are the primary feature of this NetEnt slot. Only the four premium symbols can be stacked during the regular game, but the wild symbol can appear stacked during free spins. A complete stack on a reel doubles the number of characters from three to six. The symbols with low values are never stacked.

When a full stack lands on a reel, the corresponding symbol doubles in size on that reel. A single symbol counts as two symbols. If the stack is on reel one, only one additional symbol on a payline on reel two is required to complete the three-of-a-kind. Five double symbols on a payline equal a ten-of-a-kind win.
