How to Play

You can start playing Double Stacks like this:

  1. Click on the slot to load the game
  2. Click on the settings button to read the rules
  3. Place a bet between €0.1 and €200
  4. Spin the game reels

The 5x3 slot has 10 pay lines, where you can make combinations of popular "fruit" symbols. There is also the Scatter, which is responsible for launching the bonus round. The Wild can appear anywhere in the game without restrictions, replacing unsuitable symbols in the lines.

In the slot settings, you can set the bet level, as well as the value of the in-game coin. Next to the Spin button are Auto Play and Max Bet. The first is responsible for launching the automatic spins mode, which can continue until the bonus game appears on the screen. The second allows you to quickly set the maximum possible rate.

Double Stacks RTP and Volatility

The RTP of the game is 96.1% and the volatility is high.

The percentage of return in slots reflects the amount that, in theory, players can return to their account at the end of the gaming session. It is worth noting that the game must last a very long time for this indicator to work. Therefore, it is hardly advisable to take RTP into account when planning to simply spin the slot reels for a couple of hours.

In addition, the high volatility of the slot means that the slot can bring enough ded spins but also massive rewards.



Double Stacks

Classic games rarely have impressive graphics, and this slot is no exception. Everything is simple and convenient here, from the control panel to the size of the characters. Each element of the title is well rendered, and fascinating animations take place on the screen during game events.

The game's soundtrack is also reminiscent of the old classic slot machines, with a lot of emphasis on the clinking of coins and various winning fanfare. Here you can also hear peppy music, sounding for any occasion. In general, the musical arrangement meets expectations, since the narrow "fruity" theme of the title does not allow providers to come up with something new.

The symbols of the title are various fruits such as Cherry, Watermelon, Grapes, etc. There is also the Scatter in the form of a blue chip, and the Wild, which resembles a large orange star. The highest paying element of the game is the Diamond, which pays up to 1,000x the bet.

Bonus Rounds & Free Spins


The game has 2 excellent bonuses that help increase players’ chances to get big payouts.

Double Stacks Feature

An interesting feature that allows you to get a payout of a higher level. If all identical symbols land on the reel, they will be counted as two instead of one. Thus, it is possible to get a payline 1 level longer. Accordingly, the amount of the prize will also be much larger.

Free Spins

This game feature is triggered if you manage to collect at least 3 Scatters on the grid. If during this round you can get 2 additional Scatters, the number of free games will increase. Wilds will also have special properties, landing more often on the grid in stacks.Double Stacks Slot - Free Spins

Double Stacks Demo Play

The demo version of the game offered to your attention on this page allows you to quickly explore all the features of the base and bonus rounds of the slot. In addition, you won’t spend a penny on a demo. The free version can be launched without registration or other actions.

Max Win

Maximum win — 1,000x bet.
To win the maximum payout, you need to collect 5 Diamonds on one line. If you play with small or medium stakes, you can also try to collect 3 Scatters to trigger free spins. However, remember that the minimum bet will bring minimal benefit even if you succeed. Accordingly, the rates must be raised and lowered from time to time, focusing on your own instinct and hoping for good luck.
