The polished design we’ve come to expect from Net Entertainment is present and correct in Double Stacks. The reels are made up of 4 lower value fruit symbols. Joining the melon, lemon, plum and cherry symbols are bells, bars, sevens and diamonds. There’s also a wild. Land 5 diamonds in the same payline and you’ll pocket 9 times your stake.
That rather meagre award has the potential to rocket thanks to the Double Stacks feature which offers the possibility of landing a 10-in-a-row combination. The 4 higher value symbols can all land fully stacked in the base game. If a reel is filled with a stacked symbol, all those symbols will double and count as 2 symbols. Land 10 of the diamond symbol in combination and the payout reaches 100 times your stake.
Double Stacks also comes with a Free Spins feature which is triggered by landing 3, 4 or 5 of the scatter on the same spin. You can then look forward to 5, 15 or 30 free spins. Landing 2 or more scatters during the feature will add more free spins to your current tally – up to 60 are possible.
This is a simple game but a potentially exciting one. The best winning comes from the double stacks. Fill the screen with matching symbols and some big rewards are possible. In fact, you’ll see the top payouts from the higher value symbols listed above the reels. Land a full quota of diamonds and you’ll pocket an award equal to 1,000 times your total stake.
As usual for a Net Entertainment game, there’s little to grumble about as far as design goes. If you enjoy fruit machines with a twist, then Double Stacks is one to add to the list. If you prefer more bells and whistles (i.e. bonus features and back story), Net Entertainment offers you Jungle Spirit: Call of the Wild and Warlords: Crystals of Power which are excellent.
