Theme and visuals

In the last decade, the gambling industry has witnessed huge improvements in terms of slot design and graphics. However, some people are still looking for that authentic casino vibe of the retro games. Filled with nostalgia, Stacks of Jacks free online slot is the perfect combination of modern features and traditional design, which really takes you back to the days of land-based casinos.

Oryx Gaming’s choice of visual and sound effects fits the theme perfectly. In terms of design, everything in this slot machine is simple or basic, but it doesn’t necessarily mean that it is a low-quality game. The addition of the Jack wild symbol is where modern meets classic.

The animations, together with the progressive sound effects that occur as you get winning combinations add a lot of dynamism to the game and it manages to deliver that thrilling feeling every gambler is looking for.

Another impressive title that takes you back to the times of original slot machines is Microgaming’s Break Da Bank, a robbery themed game that comes with only 3 reels and high volatility gameplay which could result in some memorable gambling sessions.


The symbols in this online slot are complementary to the theme and they are represented by the classic icons that we all know and love. There are two sets of them. One contains the retro slot high-win icons:

  • 5 Seven icons bring you 5000 coins;
  • 5 Double Bar icons also bring you 5000 coins;
  • 5 Bell icons will pay 2500 coins;
  • 5 Bar symbols will also pay 2500 coins.

The low-win symbols are pictured by fruits, such as watermelons, grapes or cherries and they will pay 2000 or 1000 coins for a combination of 5 identical ones.


This game successfully delivers a retro gambling experience to its players. The board configuration is 5 reels, 3 rows, and 10 fixed pay lines. With medium volatility and a 96.16% RTP rate, Stacks of Jacks slot offers medium-high payouts that occur frequently.

There are two ways to gamble and multiply your winnings and the stacked wilds will bring you a lot of winning combinations if you’re lucky.

How to play

New to online gambling? If that’s the case, Stacks of Jacks free online slot is the ideal game for the beginning of your adventure. It has a clear and intuitive user interface that allows you to get started right away. All you need to do is:

  • Choose a bet/line value from 0.01 to a maximum of 10;
  • Select the number of automatic spins from 10 to 250 or press Spin to go for a single round.

By tapping the Max Bet button, the maximum coin denomination will automatically be selected and your next bet will be made with C$100.

Bear in mind that this online slot is free to play. This means that your starting balance, the bets you place and any winnings resulting from them are not eligible for cash out.

Special Features

Now, this is where this game actually stands out from the crowd. While we categorized it as “retro”, it comes with some modern special features meant to spice up your gambling session:

  1. Stacked Wilds – the Wild symbols, represented by the Jacks, can cover an entire reel when they drop. You can get them on any of the reels, and they offer you a greater chance of getting a high winning combination.
  2. Guess the Card Gamble – after getting a winning combination, the game gives you the chance to multiply your winnings by guessing the color of the next card. While you only have a 50% chance of getting the right answer, the winnings double for each correct answer, which can result in a substantial payout. Of course, if you get the wrong color, you will lose all the coins, including those that you have earned from the winning combination,
  3. HighLow Gamble – if you get a winning bet, you can choose to gamble your earnings on the High-Low scale. Essentially, a scale will appear on the screen that ranges from 0 up to double the amount you won. Hitting the gamble button at the right time will double your earnings. However, there is a 50% chance that you will get a lower amount. The gamble goes on until you reach 0 on the scale or decide to cash out your winnings.


Play Stacks of Jacks slot for free and take a trip back to the reign of ground-based casinos. Available on both mobile and desktop devices, this game will for sure keep you up for a long while, especially because it comes with huge payouts that can easily be multiplied with a risky gamble.  Have endless hours of fun with this top-notch slot!
