Double Stacks is a video slot that was released in 2018 by NetEnt. The game takes inspiration from classic fruit slot machines but benefits from modern visuals that have been enhanced by the studio’s talented art team.
Available symbols in the Double Stacks slot include watermelons, plums, lemons, cherries, bells, bars, sevens, and diamonds. Stars are wild icons, while silver circles act as scatter symbols.
Double Stacks Slot Basics
The Double Stacks slot uses a 5×3 layout with 10 fixed paylines. Its volatility is high, while its RTP is 96.1%. The steep variance means bigger but less frequent payouts, which may not suit all players. Your minimum bet is £0.10 per spin, while the maximum is £200. You set your total bet by adjusting your bet level and coin value under the playing grid. The title’s top prize is 1,000x your total wager. To win, you’ll need to land three or more matching icons from left to right on a payline.

Diamonds are the most valuable symbol in the Double Stacks slot. At max bet, they award 15x your bet for landing three times, 30x for landing four times, 45x for five icons, 90x for six symbols, 120x for landing seven times, 175x for eight symbols, 250x for nine symbols, and a maximum of 1,000x for landing 10 times. After this, the sevens pay 500x, the bar 250x, the bell 100x, and the four fruit icons 60x each.
Special Features
There are several special features in the Double Stacks slot, including wild icons that substitute for everything except scatter icons.
The four most valuable icons – diamonds, sevens, bars, and bells – can appear stacked during normal gameplay. Furthermore, the number of symbols doubles if a reel displays the same icons in all positions. These doubled symbols are counted twice, which makes 10-icon wins possible.
You unlock the free spins feature by collecting at least three scatter icons on the grid. You earn five spins by default, which can increase to 30 depending on how many scatter icons trigger the bonus feature. During free spins, wild symbols can also appear stacked on all reels.
You can activate the free spins feature again by landing at least two scatter icons while it is active. Once again, the number of scatter symbols determines how many free spins you receive. Two, three, four, and five scatters award two, five, 15, and 30 free spins, respectively.

The title’s primary audience is high-rollers enticed by its volatility and the fantastic top prize, although the simple gameplay may leave a lot to be desired. Casual players can also enjoy the Double Stacks slot, provided they carefully plan out their budget, but new slot players should try something with lower volatility first.
