Spectra: How it works!

The Spectra slot lets you soar into new spheres and brings outer space onto the reels for you. The reel field seems to literally float, while the neon-colored symbols glide across the sky. The game rounds are accompanied by an upbeat soundtrack, creating the right atmosphere straight away. Accordingly, the Spectra slot proves to be a graphic masterpiece.

The slot machine has a 5×4 reel grid and is therefore a little larger than other slots. The game is played with 30 win lines that are active at all times. A payout is always awarded if at least three winning symbols of one type land on a bet line from left to right. Click on the round play button to set the cosmic reels in motion and see which bright symbols land on the reels. You can set the round bet from 10 cents to 100 euros using the coin button. Accordingly, the Spectra slot offers a solid range of applications. If you don't want to start the reels manually every time, you can use the autoplay function. Here you can set up to 5,000 automatic spins and relax a little during the game rounds.

By clicking on the menu, you can view the rules of the game at any time and also take a look at the paytable. Here you will find all payout values as well as the meaning of the special symbols. You can activate and deactivate the sound at any time using the speaker icon. This means you can adjust the game rounds perfectly to your needs.

Spectra winning symbols

The Spectra slot uses the classic winning symbols of one-armed bandits and wraps them in bright neon colors. If you want to find out about the symbol values, you can take a look at the payout table at any time. We have compiled a list of all the winning symbols here, including their meaning and payout value:

  • The wild symbol
  • The bar sign
  • The number 7
  • The bell
  • The Velcro sheet
  • The geometric shapes

The wild symbol

The shimmering letter “W” represents the wild symbol and can therefore substitute for any other winning symbol as a joker. The wild symbol completes incomplete winning combinations, increasing the probability of lucrative payouts. Furthermore, the wild symbol always appears in stacks with four winning symbols. If part of a wild stack appears on the reels, a respin including wild nudge feature will start for you. This moves the wild stack to the center of the reel during the respin. Finally, the wild symbol is the most valuable winning symbol in the Spectra slot and pays out 20 times your stake for a full line.

The bar sign

The cash symbol also makes your cash register ring and has a very good payout value. Whenever five bar symbols land on a win line, you can look forward to a 10-fold payout. Therefore, this winning symbol is clearly one of your lucky charms.

The number 7

You should also keep an eye out for the number 7 in the Spectra slot. Finally, the number 7 gives you 7 times your stake if it appears five times on a bet line. It is no wonder that this number has always had a special effect on slot machines.

The bell

The bell also heralds golden times for you. If you can hit a full row with the bell, 4 times your stake goes into your pockets.

The cloverleaf

The cloverleaf is not only pretty to look at in the Spectra slot, but also proves to be an important lucky charm. If the cloverleaf appears five times on a win line, you will be rewarded with three times your stake.

The geometric shapes

Finally, the winning symbols are rounded off by colorful shapes such as a pentagon, a diamond, a square, a triangle and a circle. These are the low-paying winning symbols that can still lead to presentable payouts. A full line with the pentagon pays out 2.20 times as much and a full line with the diamond pays out 2 times as much. Meanwhile, if the square or triangle appears five times on a win line, 1.80x or 1.60x respectively goes into your pockets. Finally, the circle awards a 1.40-fold payout for a full line. It is therefore worth paying special attention to these colorful shapes in the Spectra slot.

Features and special features

Numerous bonus features await you in the virtual space. You can look forward to these bonus features in the Spectra slot:

  • The wild symbol
  • Respins including Wild Nudge feature

The wild symbol

The letter ‘W' in the Spectra slot is bathed in dazzling colors and therefore stands out visually from the other winning symbols. There is a reason for this, because the wild symbol acts as a joker for every other winning symbol. It can fill gaps on win lines and help you win lucrative payouts. Furthermore, the wild symbol always appears as a stack of four winning symbols.

Respins including Wild Nudge feature

If a Stacked Wild lands on the reels, you are granted a respin. The Wild Nudge feature is activated during the respin. This means that the wild stack moves one position to the center of the reels. If further Stacked Wilds appear on the reels during the respin, the respins are extended. The respins only end when no more Wild stacks are added to the reel grid. With a little luck, you can score profitable full frames with the stacked wilds.


If you really took off with the Spectra slot, you might be looking for interesting alternatives. You can find out which slots offer you a similar gaming experience in the following lines.

Neon City by Wazdan

The Neon City slot from Wazdan was launched in 2019 and is similar to the Spectra slot machine in many ways. In this 5×3 reel slot, a wild symbol also helps you to win lucrative winnings. If at least three scatters land on the reels, up to 20 free games with an increasing multiplier start for you. Meanwhile, you can use the bonus meter to collect valuable winning symbols and activate 8 Mega Spins with an 8x multiplier. So you should definitely pay a visit to this virtual city.

Neon Staxx from NetEnt

The Neon Staxx slot premiered in 2015 and is equipped with a 5×4 reel grid and 40 fixed paylines. A striking feature is the original roller grid, which has a very special look thanks to its slightly slanted position. The stacked winning symbols increase the probability of lucrative payouts even further. If at least three scatters appear on the reels, you will be rewarded with up to 20 free games. Accordingly, the Neon Staxx slot is equipped with all the important bonus features.

Neon Reels from iSoftBet

With the Neon Reels slot, the game developer iSoftBet released a particularly appealing work of art in 2015. The 5×3 roller grid is presented in the form of a 3D roll. In addition to a wild symbol and free spins, the Neon Reels slot also offers diamond respins with sticky winning symbols. The highlight, however, is the progressive jackpot, which you can hit with a full row of jackpot symbols and the maximum stake. The Neon Reels slot is therefore perfect for ambitious jackpot hunters.

Play Spectra online – Our conclusion

The Spectra slot proves to be a visual eye-catcher and offers you a phenomenal reel experience. The slot machine with the glowing winning symbols promises you a few meditative rounds of gaming. As the Spectra slot focuses on just a few bonus features, it remains completely accessible even for beginners. However, fans of complex slot machines may not find much to like about the Spectra slot. Nevertheless, the respins and sticky wilds ensure that the reels can be spun again and again without betting a round. We would also like to take this opportunity to praise the fair payout ratio of 96.40%. If you're looking for an unusual fruit slot machine, you shouldn't miss out on the Spectra slot.

  • Appealing art design and accessible gameplay
  • Stacked wild symbols trigger respins including nudge feature
  • Fair return to player of 96.40%
  • No free spins available
