In 2016 Thunderkick released Spectra Slot, a simple game with no bonus rounds or free spins but exciting nonetheless for its Stacked Wilds feature that comes with unlimited re-spins – every time you land another wild, it sticks and you spin again.

Like other Thunderkick games, Toki Time and Magicious, with Spectra the team were confident enough that a great looking slot with one stand out feature doesn’t need a bonus round or free spins. And we’re inclined to agree.

The Spectra game includes simple shapes and each color of the spectrum. It has a neon futuristic feel to it, and comes with a sort of sci-fi electro soundtrack.

Key Facts About Spectra Slot

If you want to take on this high variance slot then you should get your head around these key facts:

  • There are nine symbols in the game – five geometric symbols, a clover, a bell, a number 7, a bar and a wild.
  • The top paying symbol is the bar, paying out 10x for five in a payline.
  • The low paying symbol is the blue circle, paying out 1.4x for five in a payline.
  • Your top win potential is 2,400x.
  • The Wilds always appear stacked as four and always trigger re-spins.

Stacked Sticky Wilds, Nudges and Re-Spins Feature

There are no scatters involved in Spectra Slot as there is no bonus round or free spins. But of course, there is a wild symbol and it works like this:

  • The Wilds always come in stacks of 4 – so even if you only see 1, 2, or 3, then you’ll know that there are more just waiting off the reels.
  • Wild Nudge Feature – Whenever the Wild Stacks land they will nudge up or down to get close to the center, bringing more Wilds into play on the reels.
  • After they have nudged, you are automatically credited with a re-spin whilst the Wilds stick. This gives you the chance to land MORE wilds, and get more re-spins. The more this happens, the greater your chances of hitting that big win.

This game is high variance, so be prepared to take some time before you hit a decent run of Wilds – that is where the real wins lie and it can be quite hard to unlock.  Those with smaller bankrolls, beware!

How To Win At Spectra Slot

Just to be clear, if you’re looking for a way to win at Spectra Slot, here are five quick pointers:

  1. Five on a Payline – You can scoop a decent enough payout by landing five Wilds in a row (20x) or five Bars in a row (10x).
  2. Land Stacked Wilds – Of course if you’re playing for the 2,400x top payout (aren’t we all) then you’ll need to land some Wilds. Remember, each time you get a re-spin the wilds stick so it’s possible to turn five reels wild – that’s where the big bucks are and it’s what you’re aiming for. 
  3. Play carefully – Always play safe – remember with high variance slots you can burn your bankroll pretty quickly, so choose a stake value you’re comfortable with before you start, and set your own spend limits to something you are comfortable with.
  4. Practice on Freeplay – You can always test a game on freeplay before you try playing for real. This can help you get a feel for how often and how much it will pay out. Get comfortable before parting with your own cash.
  5. Choose One of Top Listed Thunderkick Casinos – At TheSlotBuzz we have pulled together a list of the best Thunderkick slot sites. Choose one you prefer from there to try this game. Good luck!


Spectra is another top-class slot from Thunderkick, although it is a little short on features. You need to be patient before landing big wins because the Wilds don’t appear to come that regularly. However, when you do get on a run, there is huge potential here, as the 2,400x jackpot suggests. If you’re looking for more features and want to stay with the Thunderkick catalogue, we recommend you try something like Luchadora or Barber Shop Uncut.
