Take a ride through the ultimate neon-lit visual experience with Thunderkick’s Spectra slot and learn why this high-variance casino game has been winning over players ever since it was first released.
Like a classic slot machine, Spectra isn’t overloaded with features, but that’s not to say that the game can’t be rewarding at top online casinos. Thanks to its wild symbol stacks, auto nudges, and respins, this slot can quickly progress from a low-winning spin to a prize that will fill up your bankroll to the top.
One of the things players love about Thunderkick’s games is that they only feature basic screen controls. Spectra is no exception and it offers you only three intuitive controls that make playing really easy. To select a bet, just push the chip button and the slot will give you 14 bet sizes to choose between, ranging from 0.10 to 100 credits per round. Pick any of the options and then use the Auto Play or manual spin buttons to get started.
Once you begin playing for real money at the online slots sites, the slot will give you 30 fixed paylines to collect prizes on, which you can see by accessing the paytable through the menu button in your bottom-right corner. The paytable will also show you every symbol, prize, and bonus feature offered by the game. There are ten symbols in total that can pay money and all of their prizes are shown in credits. The bottom five symbols are all geometric shapes and they pay between 0.10 and 2.20x your stake per sequence while the top symbols are classic fruit machine icons and the wild and they can pay up to 20x your bet. And thanks to the slot’s special wild functions, you’ll get a unique chance to line up more than one of these wins during any round you play.
For mobile players, Thunderkick offers an optimized version of the Spectra slot which can be enjoyed smoothly on any iPhone, iPad, and Android mobile device. When you switch to playing on a phone, you get the same on-screen controls and tools, only the buttons will be placed at different areas on your screen for easier and faster access.
Once you hit the spin control and those shiny icons start falling down on your screen, you’ll need to wait for three, four, or five of the same symbols to land on a payline. To be able to trigger a prize, your matching sequences will need to start at the leftmost reel and continue towards the right side of the screen. Out of the base symbols, the most valuable icons you can collect are the bells, 7s, and BARs, which can pay up to 4x, 7x, and 10x your bet, respectively.
Still, the one symbol you’ll feel most excited about when you play through a real money casino is the wild symbol. As all wilds do, this icon can stand in for every paying symbol to help you complete one or more winning sequences per round. But what’s different about this particular icon is that it always appears in stacks of four and that it can also pay cash prizes when not substituting. Collect five of the wilds on a payline and you get a bonus prize of 20x your stake.
To help you collect more, the slot also has an auto nudge function that only applies to the wild stacks. Whenever at least one wild appears on the screen, the slot will nudge the stack towards the centre of the reel to give you more wilds. And once the nudge ends, you’ll also get a free respin with the wilds staying in their place. Any subsequent wild stack collected during the respin will then also be nudged and give you one more bonus spin. This way, you can start a chain of respins that can fill up a great portion of your screen with wilds, allowing you to amass plenty of prizes with each new respin you get.
This slot offers you fast-paced gameplay that can definitely be rewarding, giving prizes up to 240,000 credits (2,400x the bet) per round, but it’s also a risky game with a lower hit rate of 21.9%. If you’re a fan of volatile slots and traditional Vegas-style fruit machines, Spectra will be the next step to take if you want something that offers more entertainment and more bonus features, while the 96.4% RTP is higher than you'll find in a lot of land-based slots.
As a high-variance slot with broad betting limits, Spectra isn’t really a game for the inexperienced players. If you’re not really into high-variance slots, you may want to check out some of the other options on the market.
If you’re interested in low-variance games that pay less but more frequently, you can try out NetEnt’s Starburst online slot. This popular game is very similar to Spectra in a visual sense and it offers you both-way payouts, less volatile gameplay, and prizes of up to 50,000 coins per round. And for a more balanced machine, you can try Thunderkick’s medium-variance Roasty McFry and the Flame Busters slot which features a retro 16-bit design and payouts of up to 5,280x your stake. You'll find these and a whole lot more at our recommended online slots sites.
