Gameplay
Stacks of Jacks is a 5 reel slot game. It has 3 rows for symbols and a fixed 10 pay lines. All of the symbols, including the wild, appear on the reels as single symbols or they are stacked into sets of 2, 3, 4, or 5 high.
The main feature is the stacked wild symbol found on all reels. This is the joker symbol which acts as the Stacks of Jacks online slot’s wildcard. It can substitute for any of the 10 regular symbols and it pays out 200x, 50x, or 5x your spin bet when 5, 4, or 3 land on a pay line.
Regular symbols are all straight out of the classic slots scene. In order of value, there are 7s, bells, bars, melons, grapes, plums, oranges, lemons, and cherries. Overall, there are 30 possible combinations, and only 5 of them will return less than you spin bet!
7s and bars pay 50x, 10x, or 2.5x your spin bet for 5, 4, or 3 matching symbols. Bells and bars payout 25x, 7.5x, or 2x the spin bet. Then 5, 4, or 3 matching melons or grapes on a pay line awards 20x 5x, or 1.5x the spin bet. Plums, oranges, lemons or cherries 10x, 2.5x or 0.5x the spin bet for 5, 4, or 3 combinations of the symbol on a pay line.
Gameplay peripherals are spin with spacebar, turbo spin, and automatic free games entry. All these can be found under the ‘cog’ settings button. There are also options to open the paytable under the ‘$’ sign, set the reels to spin at max bet, and you can configure auto spins.
Bonuses and Free Spins
Gamble Feature: Every win will trigger the chance to double your money. Choose if the next card will be red or black. A win doubles your bet and allows you to collect or continue to gamble. Before you gamble, you have the choice to only risk half of your money on the double option which is the bet most slot players use. There is no house edge on the bet, so there is a fair 50/50 chance of winning.
Bet sizes, RTP and Variance
On the slot’s control panel, you will need to use the /- option to set your ‘bet per line’. The min-max is 0.01-0.60. The total showing in this box will be multiplied by the 10 fixed pay lines to give you a total spin bet between 0.10 and 6.00 per spin. If you want to instantly bet at 6.00 per spin, click on the ‘max bet’ option. This is a low variance slot game, and even though there are no features, you will be hitting plenty of wins often. Symbols pay out very generously with 26 out of 30 paying you back more than you bet on the spin. As for the RTP, this has been worked out as 96.16%.
Conclusion
Gamomat has taken classic slots gameplay and extended the reels and pay lines to create an entertaining 5-reel and 10-pay line classic slot game. If you are a fan of classic video slots, then Stacks of Jacks will suit you down to the ground. To add to the fun, Gamomat has added a gamble feature which is not mentioned in the paytable area, but it does appear when you win giving you the chance to double up on your winnings. Plus, regular symbols and the wild joker are all stacked giving you the chance to fill up the reels with a single symbol and activate 5-symbol combination wins across all 10 pay lines and possibly trigger the max payout of 2,000x your spin bet.
