Starsign Clusters (Gluck Games) – Review & Demo Play

Our thoughts on the Starsign Clusters theme and graphics

I’ve spent time with Starsign Clusters and the chilled-out feel hits straight away. A soothing, cosmos-inspired palette of blues, pinks and purples sits over a dark sky dotted with shimmering stars, while calm atmospheric music hums in the background. The neon-tinted elements pop against the backdrop and give the grid a dreamlike quality. It’s easy on the eyes during longer sessions, and the astrology cues feel cohesive rather than loud, which helps the relaxing playing experience land without dulling the tempo of the spins.

RTP and variance in Starsign Clusters

On the numbers front, Starsign Clusters runs a 97.5 per cent RTP, which sits above many releases. The volatility sits in the medium bracket, so sessions tend to mix smaller clusters with occasional stronger sequences rather than bone-dry stretches or wild spikes. The stated top win lands at 5,000x the bet, which feels aligned with the feature set. It’s a configuration that suits steady, readable play while still leaving room for a session to lift when multipliers and features stack during a good run.

How to play Starsign Clusters

Getting started on Starsign Clusters is simple. Use the left and right arrows to set your stake, open the menu for the paytable and rules, then hit the central round button to spin. I keep the sound on low and pace the session at a comfortable clip. Self-exclusion and timeout tools are available if you need them, and I always treat this as entertainment rather than income. A quick skim of the help pages makes the feature triggers and symbol values clear before you begin.

The game uses a 6x6 grid and a cluster-wins style. You land a payout when at least four matching symbols touch horizontally or vertically on adjacent squares. After every win, the cluster is removed and new symbols drop to fill the gaps, so you can chain prizes from a single stake. This cascade rhythm keeps the board lively and sets up the multiplier mechanics that sit on top. It’s an intuitive loop that most players can read in seconds.

How to win at Starsign Clusters

To win well on Starsign Clusters I chase momentum. Each successful cluster triggers a cascade, and a win multiplier applies to the next winning combination, rising by +1 each time during that sequence. When the board clears without a new cluster, the chain ends and you reset. Locking scatter symbols can drop and stick to help towards feature triggers and jackpots, so I pay attention when they start appearing together. The core aim is simple, but runs can build fast when grids co-operate.

Top symbols in Starsign Clusters

Top symbols in Starsign Clusters follow the theme neatly. You get the sun plus five neon triangles tied to the elements, such as a green leaf for earth, a blue drop for water, a pink twister for air, and an orange flame for fire. Everything stands out against the dark background, which helps spot clusters quickly. The set is clean and readable, and I found the colour coding handy when tracking potential joins during cascades, especially on sequences that run a few wins deep.

The paytable highlights the orange lightning bolt as the standout, paying 10x the bet for a cluster of seven or more. At the other end, the sun sits at the bottom with a top return of 2x. There are six winning symbols in total, so values are easy to learn after a few spins. With clusters paying anywhere on the grid, you are not staring at lines, just watching groups grow and pop, which fits the relaxed tempo of the slot.

Bonus features in Starsign Clusters

Bonus features in Starsign Clusters arrive often enough to keep the base game lively. After every cluster, the multiplier applies to the next win and steps up by +1 with each successive cascade. That means even modest groups can begin to matter if the board keeps feeding fresh joins. Because the removal and drop mechanic repeats until no new cluster forms, a single paid spin can generate a neat ladder of prizes, which pairs well with the medium volatility profile.

Power mode and the jackpot wheel sit above the grid. Five triangular power meters charge when you land the required number of matching symbols. Filling one triggers the wheel, which can award free drops or hefty cash prizes. I like this layer because it gives visual targets during base play, and when a meter is close you feel the pull to complete it. The wheel outcomes vary, but the prospect of a feature or a chunky hit adds welcome texture.

Free drops land via scatters. Four scatters award 12 free drops, five award 14, six award 18, and seven or more award 22. The win multiplier stays active through the round and does not reset between spins, which is where things can escalate. There is also an astrological bonus pick mini-game that appears when four to seven wheel symbols land, giving two to five picks at random cash prizes that are added to your pot at the end.

Starsign Clusters review summary

I came away impressed by how chilled Starsign Clusters feels without slipping into dull territory. The cluster mechanism is a nice change of pace, and the medium volatility backed by a 97.5 per cent RTP plays into steady sessions that still have bite. Visuals are soothing, the soundtrack is low-key, and the board state is always readable, which suits quick check-ins as well as longer sits when you fancy a calm spin.

The free drops can arrive like a meteor shower, and when the multiplier sticks between spins the round gets exciting fast. Between cascades, power meters, the jackpot wheel, and the bonus pick, there’s enough going on to keep me on my toes. I would call it a relaxing slot that still has teeth, with a top win of 5,000x acting as a clear ceiling. If you like a chilled-out grid game with a soothing palette, Starsign Clusters fits the bill.
