Double Stacks Slot Essentials
Double Stacks online slot can be described as a classic fruit-themed game with a twist. Read through the following sections for more details.
Theme, Storyline, and Graphics
The Double Stacks slot has a familiar theme typical of classic slot machines. Colourful symbols, such as cherries, bells, and BAR symbols, are present on the reels, and relaxing electronic music plays in the background and accompanying each spin.
Symbols and Payouts
The game has low-paying and four high-paying symbols, and you need at least three-of-a-kind on a payline to form a winning combination. The Star Wild symbol replaces other symbols except for the Scatter to form more wins, while the Scatter is your key to a bonus feature.
| Symbol | 3 on a Payline | 4 on a Payline | 5 on a Payline | 6 on a Payline | 7 on a Payline | 8 on a Payline | 9 on a Payline | 10 on a Payline |
|---|---|---|---|---|---|---|---|---|
| Watermelons, Plums, Cherries, Lemons | 0.5x | 1x | 2x | 3x | 4x | 5x | 6x | – |
| Bell Symbols, BAR Symbols | 0.5x-1x | 1x-1.5x | 2x-3x | 3x-6x | 5x-7x | 6x-9x | 8x-12x | 10x-25x |
| Lucky 7 Symbols, Diamonds | 1x-1.5x | 2x-3x | 4x-4.5x | 8x-9x | 10x-12x | 15x-17.5x | 17.5x-25x | 50x-100x |
Double Stacks Bonus Features
The online slot offers three distinct bonus symbols:
- Stacked Symbols — Any of the four high-value symbols in the game can land as a stacked symbol and boost your chances of winning big.
- Double Stacked Feature — If you land a reel where all symbols are of the same kind, they will count as two for payouts.
- Free Spins — By landing 3, 4, or 5 Scatters, you get 5, 15, or 30 free spins with Wild symbol icons and Stacked Reels. Two or more Scatters during the spins will retrigger the feature and award up to 30 additional free spins.
Bet Sizes, RTP and Variance
The 96.10% Return to Player rate of the Double Stacks slot indicates that players can potentially get back $96.10 for each $100 wagered.
Since volatility sits in the high brackets, you can expect scarce but massive payouts if you are lucky to form a winning combination. The game offers a wide betting range — $0.10-$200 per spin and suits all types of players and budgets.
