Expert Review: James Gibson's Verdict & Opinion

Ultra Cluster Kingdom: A Regal Slot With Exciting Gameplay and Great Features

James Gibson rated this game:

4 out of 5

Ultra Cluster Kingdom whisks you away to a majestic place where royalty resides. The slot has beautiful graphics, a relaxing soundtrack, and, last but not least, gameplay that’s very enjoyable. It has a seven-reel grid with four to eight symbols on each reel, plus it uses cluster pays and has tumbles with an increasing multiplier.

When playing Ultra Cluster Kingdom, I liked the features and mechanics, though I didn’t win too often. Most of my wins were on the smaller side, i.e. 5x my bet or less, even with tumbles and multipliers potentially boosting payouts.

Having said that, I did win 37x from the free spins round. What I liked about this was that the multiplier from tumbles didn’t reset from one spin to the next. The longer the round went on, the greater the potential for bigger payouts was.

I also decided to take advantage of the purchase option and buy the free spins round. When I did this the first time, my return was a decent 88x. However, the cost of buying free spins was 100x, so I ended up making a loss. I decided to make the purchase a second time, though again I lost money; this time, my win was a bit less at 69x. 

The free spins round was definitely the highlight of the slot, and I was glad there was the option to buy it. The downside, of course, was that I didn’t make my money back either time. Still, it was a fun round with tumbles giving me extra chances of winning and the multiplier that grew with every win not resetting.

Would I recommend playing Ultra Cluster Kingdom? Absolutely. It was a great slot to play and had some cool features that made the gameplay unpredictable and enjoyable. Give it a spin but think twice about buying free spins because it may not always be worthwhile.

PROS
  • Great theming and visuals
  • Cluster Pays
  • Seven reels with four-eight symbols 
  • Tumbles with an increasing multiplier
CONS
  • Buying free spins isn’t worthwhile
