Cluster Slide is a video slot game from the developer ELK Studios. The game features a changeable gravity grid with a 7 x 8 reel. Players can roll up to five joker modifiers. With this, clusters of winnings fill the counter for a regular one to be given out. A real multiplier of +5 will increase when all five clusters are activated in the same round. This way, you can win up to 10,000 times directly from the wild symbols. Their size increases after any free bonus round.
The slot’s gravity mechanics are designed innovatively and elegantly to make their way into the mainstream. The slithering, fluffy and oscillating gel monsters look innocent as they open their eyes on a winning group. Before you know it, they’ll devour each other to then grow in size. The five unique joker modifiers are fast enough to hide the game’s volatile nature. You’ll hardly even have time to look back when the game changes unpredictably.
Each time a cluster of at least five matching symbols appears, a sliding avalanche option is triggered. The winning symbols are removed first, after which the remaining symbols are sent to their own places in full compliance with the laws of gravity and a set of tilting reels. Next, a new set of symbols is rolled out to fill the remaining gaps. This process is repeated as long as the gamer continues to win.
There are quite a few jokers in this game. The standard blue/pink “W”-symbol lands at any time to form winning groups by the player. At the same time the winning symbols are able to collect above the grid in the generator counter. It must be filled in an avalanche sequence. Otherwise it is reset. When filled, the player will be given one of five wild modifiers:
Random – turning two to four standard symbols into jokers.
Large – increasing the random symbol to 2×2.
Remove – this removes all instances of the same kind of symbol from the grid.
Enhance – enhances random symbol type to a high level.
Multiplier – the winnings are increased by +1.
The Wild Drops bonus round requires three bonus gold ‘B’s’ to trigger. The player receives 3 freespins. Each Wild Drops symbol becomes a wild on the first occurrence. The gambler gets extra 1×1 symbols, then a few 2×2 jokers on a free second roll, and the third extra will give him a 3×3 joker.
ELK X-iter is a feature for use in jurisdictions with an allowed bonus purchase option (except the UK). The standard bonus round is worth 100 times the bet made by the player.
You can also buy other wild options or pay for the 300x super bonus round, which will give the gambler as many as five instead of three roll-outs. In addition, he will get three and four 2×2 symbols in the last few spins respectively.
To conclude the review, Cluster Slide is mechanically and visually perfect. The volatility sometimes makes unpleasant surprises, but on the whole it only pleases. With that said, the Super Bonus Round offers a chance to win 10,000 times the bet amount. Even picky players have plenty of room to run wild!
