Spectrum (Wazdan) stands out with a modern take on classic slots, blending a stripped-back jewel theme with sleek, retro vibes. There’s no complex story here—just a clean grid of sparkling precious stones with a color palette that looks like a light beam passing through a prism. With only 5 reels and 10 bet ways, the slot feels refreshingly uncluttered, ideal for players who appreciate straightforward action. But don’t mistake its simplicity for dull gameplay. Beneath the glitz and electronic soundtrack, Spectrum (Wazdan) can surprise, mainly because of its ‘pay both ways’ mechanic and re-spin wilds.
The first thing that jumps out is how easy it is to get a handle on the core action. Spectrum (Wazdan) slot is built around 10 fixed paylines that pay left-to-right and right-to-left. Hits happen more regularly than on many video slots, but the base game has a distinctly even, almost meditative rhythm. With so few paylines, it can go stretches without big wins, but the moment those expanding wilds appear, the dynamic shifts fast.
Wilds appear only on the three center reels. When one lands, it instantly expands to fill its reel and grants a free re-spin, locking the wild in place. If another wild hits during the re-spin, it expands and adds another respin, up to a maximum of three. Chain reactions are possible if luck is on your side. There is real excitement when one wild triggers another, especially since paylines pay in both directions, effectively doubling every chance you have of scoring multiple lines at once.
Expanding wilds are the headline feature here, and they show up often enough to keep things interesting but not so frequently that they feel routine. In extended play, it takes patience, but those bursts of wild-triggered respins can pay off, especially if you line up premium symbols at the same time.
Beyond wilds, the classic gamble feature is another nod to traditional slots: after any win, you get the chance to risk your payout in a double-or-nothing game, with up to seven rounds in a row if you keep guessing right. It’s a simple mirror-picking decision, nicely themed to match the slot’s light-and-reflection motif. For those who like volatility, it offers a controlled way to push your luck further.
Uniquely, Spectrum (Wazdan) gives you control over volatility. Before spinning, adjust between low, medium, or high variance. This noticeably affects game flow—even small bets can feel tense if set to high volatility, where wins are scarcer but chunkier when they do drop. The difference is tangible: low volatility brings more frequent, smaller wins, while high settings can test your patience but build real suspense.
Spectrum’s official RTP clocks in at 96.30%, putting it a touch above average compared to other online slots. Over time, it plays close to this; in practice, the adjustable volatility option lets you steer the session towards shorter, frequent payouts or longer, high-risk spins, depending on your mood. Hit frequency isn’t sky-high, but with the double-sided win mechanic, the potential for frequent line wins is doubled compared to many five-reel games.
Because the maximum win tops out at 300x per line for Bars, truly huge payouts are rare—especially as there are no built-in multipliers or bonus games to stack up extra value. Players who thrive on adrenaline and massive jackpots might find Spectrum (Wazdan) a bit reserved, but those who favor steady pacing and manageable risk will appreciate the structure. The bet range is broad enough to suit both cautious beginners and those wanting higher stakes action, especially given the ability to tweak volatility.
One of the best ways to get a feel for this game is to try the Spectrum (Wazdan) demo mode. Most reputable casinos hosting Wazdan titles offer Spectrum (Wazdan) free play, which mirrors the real money experience but with play credits instead of cash. This lets you test different volatility settings, see how wilds behave, and mess with the gamble game, all risk-free before deciding whether to stake real money.
While Spectrum (Wazdan) doesn’t have any exclusive free spins bonus rounds, it does qualify for most site-wide welcome packages and free spins promotions. Many trusted casinos feature the game as part of their general welcome offers, giving you a chance to use those bonus funds or spins for your first sessions. Always check the terms, but nearly all Wazdan-partnered operators provide access to both demo and real bets.

Spectrum (Wazdan) is best suited to those who enjoy classic slots but want a modern touch—especially the ability to pick volatility. If you're looking for similar experiences with more complex bonus layers, try Starburst (NetEnt). While also paying both ways and heavy on visuals, Starburst adds expanding wilds but with a slightly higher spectacle and more frenetic pacing.
Another option is Twin Spin (NetEnt), which similarly channels the retro slot ethos but spices things up with linked reels and higher hit frequency. For players who crave a similar jewel-themed slot but want extra features and multipliers, Gemix (Play'n GO) offers cluster pays, a range of power-ups, and a much more energetic flow. Compared to these, Spectrum (Wazdan) is a bit more laid back, making it ideal for those who want control and straightforward features rather than non-stop action.
Spectrum (Wazdan) review wraps up as a solid choice for those who like their slots neat, with enough volatility flexibility and wild-driven action to keep things engaging. It’s missing headline-grabbing multipliers or complex bonus rounds, but the twin pays and expanding wilds give it presence.
