Zipper Slot

Zipper Slots

We’ve heard of some fairly strange and unusual topics that online slot machines have been themed around. But Zipper from Merkur buttons down the question of what the weirdest theme can be. It’s loosely based on the humble zip, with a background image that has giant zips above and below the reels, plus a bonus round which also features this useful device.

But don’t get caught up in this zipper, as there’s a rich variety of other symbols such as an open book, a crystal ball, a top hat, and someone we assume is a magician. What’s all this got to do with zips? Not much, but don’t zip off to another slot machine until you’ve checked out this review. Then play the Zippe slot at a safe and reliable online casino for free or real cash.

Zipper is a five-reel slot crossed by a selectable five or ten paylines. It comes with a standard winning format that pays whenever you land matching symbols from the left side across a payline, and it has a couple of equally standard features such as wild substitutions and a scatter symbol. Extra wild symbols can appear during the bonus games and then get unzipped at the end. A gamble round that can be played in two different ways is another exciting feature, and lucky spinners will be able to multiply any win several times over.

The reels are surrounded by red curtains held in place by the zippers, and a nice design touch is the way each reel is separated by more zips. Starry backgrounds to each reel contrast with the glowing playing card symbols that will award you the smaller prizes. A fun soundtrack that changes tune when you land wins or enter the features livens things up in this fast-paced game from one of the top German games developers. Merkur has a strong background in the manufacture of slots for land-based casinos, and with the move to online and mobile-optimized games, it could soon have a larger part of the market all sewn up.

The Zip Code

Reading the paytable, you can see how many times the amount staked on each line is won with different combinations of symbols. Landing either the 9 or 10 symbols on three, four, or all five reels will award prizes of five, ten, or 30 times the line bet, while the J, Q, K and A pay high limits of 50, 75, 100, or 125 times respectively.

The blank pages of the open book are worth 60x, 125x and 300x the per line stake, which is nice, but we’re still not entirely sure what this symbol has to do with anything else connected to the game. Never mind, maybe we should just forget about it and enjoy the winnings. The magician is valued at up to 400x, and the crystal ball pays 100x, 200x, or 500x when it stops on three, four, or five reels across a line.

The crystal ball is also a wild symbol, made obvious by the word ‘WILD’ written in big letters right across it. This gives it the ability to act as others if it then means that extra combinations of symbols can be created. It can also boost the value of a win by extending the run of matching symbols further across to the right side of the game. We predict that in the near future, this crystal ball will help add funds to your bankroll.

Pulling Free Spins From a Hat

The magician’s hat is a special scatter symbol that awards six free spins when it stops in three places at once. Four examples of this symbol will trigger 12 bonus games, and 24 free spins will start as if by magic when the hat is seen in five or more positions at once.

Each time the hat symbol appears in a free game, it will add five extra wild symbols onto the reels to give you a great chance of collecting some big wins. It’s all accompanied by some fun animations where a magic wand undoes zippers to reveal the additional wilds.

A single hat will also add one more spin to the total, while two hats grant three more free games and the whole round gets retriggered by three, four, or five hat symbols. That’s on top of all the extra wilds that can appear, turning this weird but wonderful bonus feature into something special.

Gamble Games

Merkur slot machines tend to come with optional gamble rounds, and this one is no exception. When you win a prize, you’ll be offered the chance to play the card gamble, or ladder feature. The card game is a simple 50/50 guess on the color of a face-down playing card, which doubles your win if you get it right and loses it for a wrong pick. You can collect the win or go again if you're right in your choice of color.

The ladder feature is a bit more interesting, and at least it’s different to the standard card round. You’ll see various prize values on a ladder, including the amount you have just won, with flashing lights above and below it. Correctly timed clicks stop the light on the higher value, and you can carry on or collect the new prize. Of course, getting it wrong takes you down the ladder, but not right to the bottom. So you still have the chance to rescue the win.

Betting Buttons

A simple set of control buttons adjusts your bet per line from just 0.01 to 0.40. Play all ten lines, and you’re looking at a maximum wager of just 4.00 per spin – which is a real disappointment and sure to put off high rollers. Free Zipper video slots are available, but with just 0.05 needed per spin when you go for the five-line option, why not just play for real cash?

The only other options in front of you are whether to spin the reels automatically for up to 100 times; as well as to decide whether you want to play on iPhones, iPads, Android or Windows devices, or to access Zipper on a desktop PC.

Similar Slots

We searched long and hard to bring you details of another game based on clothes fasteners, and perhaps unsurprisingly, we failed to find one. There’s probably not much demand for them, but maybe one day we’ll see slots based on buttons, zips, poppers and laces.

However, there are plenty of online casino slots based around magic which see magicians, hats and crystal balls fill the reels. One of the biggest hits from this genre is Fantasini Master of Mystery from NetEnt. It’s a beautifully crafted slot machine that features a magician, his assistant and various tools of his trade on the five reels. A 243-ways-to-win layout and at least two reels linked together on every spin help to make this a thrilling game. If all five reels are linked, showing the same symbols across the whole game, you’re in for some fantastic rewards from Fantasini.

Zipper-Dee Doo Dah!

There’s no denying that the Zipper video slot is pretty unusual, with a theme that mixes zips with magic. We enjoyed it though, as the wins come fairly easily across the paylines, especially in the 10-line mode. In addition, the free spins round is actually an outstanding feature.

It’s got a fairly high return-to-player percentage of 96% and is certified as fair, reliable and trustworthy. Button down this game at Merkur online casinos, and you could be enjoying a unique game which won’t have you unzipping your wallet too often.
