Double Stacks, produced by NetEnt, is currently our Slot of the Week at TwinSpires Casino. Simply opt into the promotion, spend $10 on Double Stacks, and you'll get 20 free spins. How cool is that?

Double Stacks has a super, soothing soundtrack that carries you along while you spin, admiring the classic but beautifully animated symbols. There are fruits, diamonds, 7s, and BARs - and the gameplay just feels… relaxing.

Simply the Best

With five reels and three rows, there are just 10 paylines, so nothing too complicated to distract you as you enjoy one of life’s simple pleasures. It’s a slot machine that does not blast cinematic sounds, or confuse with thousands of ways to win and bonus games that you need a degree to understand.

Instead, simply match up the symbols. Diamonds are worth the most. Get 10 of these gems, and you could win 1,000 times your original stake. The 7 symbol is next in value, followed by the BAR, the bell, and then the juicy-looking fruits.

Wilds replace any symbol (apart from scatters) to increase your chances of making a winning line. Get three or more scatters to launch the free spins bonus mode, with anything from two to 30 free games available. Two scatters for two more spins, three for five, four for 15, and five for another 30.

The slot’s name comes from one additional feature. The four top-paying symbols can appear stacked down a full reel. Each of these will count as a double win if any line is completed. During the free spins feature, wilds can also be stacked, plus you can land further free spins with more scatters.

With an expected return to player of 96.1%, Double Stacks is considered a high volatility slot, meaning that wins tend to be larger but come along less frequently.
