Cosmic Clusters: A Dazzling Space Slot with a Host of Features
James Gibson rated this game:
4 out of 5
As you can tell from its name, Cosmic Clusters is a space-themed slot where you win by forming clusters of matching symbols. It has a dreamy, fantasy-like feel to its design, which I like, and comes with lots of features to make its gameplay enjoyable and possibly rewarding.
One feature in particular I liked was the tumbles. These are a feature of many slots, but in Cosmic Clusters there are two extras: all symbols that match the winning ones disappear and a wild is added to a random empty space before the gaps are filled.
Thanks to tumbles and the extra mechanics, I was able to earn a few decent payouts in the slot’s base game. The most I won was 19x, which came about thanks to multiple consecutive tumbles and clusters of high-paying symbols getting formed.
The other big payouts I earned were 8x, 7x, 7x, and 6x. Wins were fairly regular in the base game thanks to the slot’s medium volatility. Of course, I hoped to play the free spins round, but I never managed to land enough scatters.
I therefore decided to buy it for the cost of 100x my bet. There were two more expensive options, but I stuck with the cheapest one, not wanting to take too much of a risk. I got 12 free spins and won 73x in total.
Even though I made a loss, it could have been much worse. Also, I’ll point out that I made 66x on a single spin in the round, thanks to high-paying symbols, coin prizes, tumbles, and wilds. I hoped to get a few more spins like this, but that didn’t happen.
The free spins round can be very volatile. If you decide to play Cosmic Clusters, which I recommend, bear this in mind when deciding whether to buy free spins or not. Whether you make the purchase or not, the slot’s still a lot of fun to play.
PROS
Tumbles with an extra wild added

Entertaining space session
Really enjoyed the vibe here. The momentum stayed consistent and the multipliers made for an entertaining session. Grabbed a $52 win, definitely coming back for more cosmic action.
