Cluster Buck Review

The slot’s title might invoke a slightly negative feel but there's certainly nothing bad with a grid that can explode into a modifier frenzy with jackpot prizes and a chance to play for free. On paper, this one's got it all going on!

Gameplay & Features

The most important thing to remember here is that you aren't working with any paylines and you can grab wins by landing groups of matching symbols. This is a cluster pays mechanic and that means matching symbols must touch horizontally or vertically, but they can fall anywhere on the grid. 

A minimum group of five is required to pick up a win. The lowest paying symbols will get you 0.10x and the highest paying symbols will get you 1x. This is the lowest tier payout and will hopefully grow when the cluster bar comes into action. 

Each time wins occur, a number of winning symbols are removed and new ones come to join the grid. Winning symbols are added to the cluster bar and if you complete the bar, you upgrade to the next tier. Eventually, the lowest paying symbols can be worth 300x and the highest paying ones might produce values worth 3,000x. 

Symbols can land as single, double or quadruple symbols and this should help to improve your chances of landing some wins. Wild symbols can do the same and will substitute for other regular payers. 

Padlocks fall from time to time to lock the progression on the cluster bar. Beyond that, bonus bombs will explode and take out symbols in up to four directions with regular ones simply taking out symbols and replacing them with new ones and wild bombs replacing them with wild symbols. 

If a chest lands, you have a chance to land another one and once you have a pair of them, you might reveal a load of wild symbols. Alternatively, you could trigger the jackpot bonus. Here, you simply spin the wheel and you’re guaranteed to pick up one of the jackpot prizes worth up to 5,000x. 

Bonus Game 

The free spins bonus requires 3 scatter symbols and once you've made your way into the bonus area, you'll see 8 free spins. During the free spins game, the cluster payout continues and not much changes other than wilds can now upgrade to doubles and quads, which you couldn't achieve before during the base game. 

There are two buy bonus options available outside the UK and these cost 100x and 200x. The difference between the two is that the regular bonus game is the one described above and the super bonus game produces more wilds and more wins.

Cluster Buck - Cluster Bar

Cluster Bar

Each time you land a win, the corresponding cluster bar will begin to fill with the symbols that are involved in the win. The more symbols that land, the quicker you will fill the bar. As you move on to the next tier, the symbol values improve and you can make the highest value symbols grow from 1 up to 3,000x.

Cluster Buck - Bombs

Bombs

Bomb symbols are able to transform the grid in a couple of ways. Hopefully, both will have a positive effect on your payouts. The standard bomb will land and explode in up to four directions, taking out regular symbols and replacing them with others. The wild bomb will do the same but this one replaces the exploded symbols with wild symbols.

Cluster Buck - Jackpot Bonus

Jackpot Bonus

Picking up a jackpot bonus requires a chest to land on the grid. When one chest lands, you have a chance to land the all-important second one to pick up either a group of random wilds or you'll trigger the jackpot bonus. You spin the wheel and you’re guaranteed to get one of the four jackpot prizes. Jackpots are worth between 20x and 5,000x.

Cluster Buck - Free Spins

Free Spins

The free spins bonus will come your way when the happy-looking star appears during the base game. You'll need three of these to produce eight free spins and now you'll see a little upgrade occur. When a wild upgrades, it will become a double or quadruple symbol. Players outside the UK can buy directly into the bonus feature for 100x or 200x.

Win Potential

For me, the win potential didn't improve vastly as I moved from base game to bonus game but that was to be expected as there's only a chance of upgrading the wild symbols and not much else. If you buy your way into the super bonus game, who knows what those extra wins will produce. Improving the symbol tiers can be a little tricky as you need to continuously pick up large clusters but the padlock symbols might help. If all goes well, you could reach 12,000x.

Design

This slot features a cutesy design with the main star character offering his services to take you into the bonus game. A little celestial action is animated behind the grid and either side of the game area, you'll see the cluster bar and jackpot prizes. The sound effects are quite pleasing as new symbols land and you're also treated to a fun and simple soundtrack to keep your spin finger happy. The whole show is available to watch on mobile phones as well.

Our Verdict

There is plenty going on in Cluster Buck with modifiers, including bombs, large groups of symbols and those payout upgrades. In theory, you could see some incredible prizes if you reach the higher tiers but in practice, you're going to need to be very lucky to keep the same group of winning symbols coming time and time again. It makes little sense to me that this is a medium volatility game as it felt like the large payouts were few and far between, but when they did turn up, they were pretty special!
