How many times have I seen these fruit machine symbols appearing in different games over the years? Ooh...countless of times..going as far back to the days when slot games ran on individual computers, when online gaming was still non-existent! These symbols are therefore the most commonly and frequently used to create all sorts of games, from the basic 3-reels 3-rows games up to multiple reels and rows games. The differences between these kind of games lie in the characteristics of the symbols or in the features they can award.

As the name of the game implies, this Double Stacks game can double-up the top 4 symbols to create a screenful of same doubled symbols, for some impressive payouts - well, that's what the paytable says anyway, but that's another story, because when I looked at the paytable, I wasn't impressed at all! For a 10-paylines game, the win values for all the symbols are actually very low, if not extremely low, so most of the time, you can only expect to get disappointingly poor payouts, except on a very few and rare lucky occasions!

A Free Spins Game is one of the most important feature of any game, as far as I am concerned. In Double Stacks, 3 non-paying Scatter symbols would award 5 free spins, without any win multiplier...yep, only 5 blardy free spins with a zero multiplier! Argh! There isn't any retriggering possibility, but getting 2, 3, 4 or 5 Scatters during a free spin would add 2, 5, 15 or 30 more free spins. Yeah right...try getting any of the extra Scatters during the initial 5 free spins and you would see how difficult everything really is!

Oh, before I forget, this game also offers 4 Jackpot Prizes, one for each of the top 4 symbols, from 100x up to 1000x the total bet amount. Getting all of the same symbols on the reels would award the corresponding jackpot prize. Impressive? Nope, not to me it isn't! Games like Book Of Dead, just for example, can pay 100x the total bet for getting all of the lowest symbol, whilst the top symbol can pay 5000x, so what is 1000x, right? Sorry NetEnt, but you cannot simply fool everyone!


In short, I don't like playing this Double Stacks game - the paytable sucks, the wins suck, the jackpot prizes suck, and the game got me bored rather quickly too! Sheesh!

Double Stacks is powered by Net Entertainment and is a 5 reel, 10 payline slot. With a neon/fruity style theme, it comes with stacked symbols and a double stack feature where a reel showing the same symbol is duplicated to give you double wins. There’s also a free spin feature where you can win up to 60 free spins with the wild appearing on the reels or in stacks.

Double Stacks reminds me of twin spin deluxe, which is a game I do not like, however the possibility to win the maximum during free spins are much better than twin spin deluxe or joker pro. The sound track is just chilled, and the graphics are good.

Symbols on the reels include watermelons, plums, lemons, cherries, bells, 7s, bars and diamonds. There’s also a wild symbol which substitutes for all symbol but the disco ball scatter. Above the reels you will see the maximum pay-outs for the 4 highest value symbols. You can achieve these amounts by filling the screen entirely of that symbol. The 4 high paying symbols, the diamond, 7, bar and bell, can appear stacked on the reels to help you win more. Just remember missing one symbol of the full screen can mess up the win and make it very small.

Now, when a reel stops and all symbols on that reel show the same stacked symbol, the double stacks feature is triggered. All symbols on the reel will then double. This means that the symbols on the reels will count as 2 symbols instead of 1. If you were to fill all the reels with double diamond symbols, you’d win 1,000 times your stake.

Double Stacks also comes with a free spins feature, when you get 3 or more scatters anywhere on the reels. If you get 3, 4 or 5 disco ball scatters, you will get 5, 15 or 30 free spins respectively. During the feature, the wild symbol will also appear on the reels or in stacks. Getting 2 or more scatters during free spins, awards extra free spins.

The slot is simple and very rewarding during free spins. The game is all about the free spins. I once managed to win x200 but on average x100 or just below.


Base game sucks and does not pay well. Free spins can take forever to trigger.
