Spectra Review

Thunderkick's Spectra isn't just a slot; it's a symphony of high-tech design and gaming ingenuity that is sure to captivate players seeking an unforgettable thrill. Explore the cosmos of slots with Spectra – where every spin is a journey into the extraordinary.

Spectra Features

Spectra boasts a trio of cool features – the Nudge Feature, Respin Wild, and the electrifying Wild symbol – ensuring a dynamic and engaging gameplay experience. With these innovative elements, players are in for a thrilling adventure filled with surprises at every spin.

Nudge Feature

In Spectra, the Nudge Feature is a unique gameplay mechanic that adds an extra layer of excitement. When a partial stack of Wild symbols appears on the reels, the Nudge Feature comes into play. It nudges the partial stack, causing it to expand and cover the entire reel. This not only enhances the visual spectacle of the game but also increases the chances of forming winning combinations. The Nudge Feature in Spectra essentially gives players a second chance at a winning spin by manipulating the positioning of the Wild symbols. This dynamic feature adds an element of strategy and anticipation to the gameplay, making each spin a potential source of thrilling outcomes. As the reels nudge into alignment, players witness the transformative power of the Nudge Feature, creating an engaging and rewarding experience within the vibrant world of Spectra.

Respin Wild

The Respin Wild feature in Spectra introduces an exciting twist to the gameplay. When a Wild symbol lands on the reels, the Respin Wild feature is triggered. Once activated, the Wild symbol becomes a sticky wild, locking in its position on the reel, and the remaining reels spin again. During the respin, if additional Wild symbols appear on the reels, they also become sticky, and another respin is awarded. This process continues until no new Wild symbols land on the reels during a respin. The Respin Wild feature not only adds suspense to the game but also increases the potential for significant wins as more Wild symbols accumulate on the reels.


In Spectra, the Wild symbol serves as a versatile and powerful element that can significantly impact the outcome of each spin. The Wild symbol in Spectra has the ability to substitute for other symbols on the reels, except for special symbols such as scatters or bonus symbols. This substitution feature enhances the chances of forming winning combinations by helping complete or extend existing paylines. Moreover, in Spectra, the Wild symbol plays a crucial role in triggering the Nudge Feature and the Respin Wild feature. When a partial stack of Wild symbols appears on the reels, the Nudge Feature is activated, nudging the stack to cover the entire reel and potentially creating more winning combinations. Additionally, when a Wild symbol lands on the reels, the Respin Wild feature is triggered, leading to respins with sticky Wilds and the possibility of accumulating more Wild symbols for enhanced winning potential.

Spectra Unique Features

At the heart of its innovation is the Nudge Feature, a gameplay mechanic that activates when partial stacks of Wild symbols grace the reels. This feature introduces dynamic reel nudges, causing the partial stacks to expand and cover entire reels, ultimately enhancing the potential for creating winning combinations. It's a distinctive element that adds an exciting layer of strategy to each spin.

Complementing the Nudge Feature is the Respin Wild feature, further elevating the slot's excitement. When a Wild symbol lands on the reels, it triggers the Respin Wild feature, turning the Wild into a sticky symbol. Subsequent respins occur as long as new Wild symbols continue to appear, creating a thrilling cascade effect. This not only prolongs the suspense but also increases the chances of accumulating more Wild symbols, thereby enhancing the overall winning potential.

The Wild symbol in Spectra plays a multifaceted role, acting as a versatile substitute for other symbols on the reels. Beyond its substitution function, the Wild symbol serves as the linchpin for triggering both the Nudge Feature and the Respin Wild feature. 

Spectra Winning symbols

In the vibrant world of Spectra, winning symbols come alive, each offering its unique rewards. At the forefront is the Wild symbol, distinguished by its neon lettering, not only serving as a versatile substitute for other symbols but also triggering the coveted bonus respins feature. These Wild symbols always appear in stacks of four, and the electrifying prospect of a x20 payout awaits lucky players who land five of them on a pay line.

Spectra Winning symbols

The Bar writing takes center stage, providing payouts ranging from x1 to a substantial x10 of the bet, adding an element of high-reward anticipation to the mix. The iconic seven symbol brings its charm, offering rewards from x0.7 to x7 of the bet, while the melodic bell and fortunate clover follow suit, providing payouts from x0.5 to x4 and x0.5 to x3 of the bet, respectively.

The geometric elegance continues with symbols like the pentagon, rectangle, triangle, square, and circle, each contributing to the slot's visual appeal. These symbols offer varying payouts, introducing a layer of strategy and excitement to each spin. From the pentagon with payouts ranging from x0.3 to x2.2 of the bet to the circle with payouts from x0.1 to x1.4, Spectra ensures that every symbol on the reels holds the potential for thrilling rewards, making each spin a captivating journey into the heart of geometric fortune.
