Slot Details

Professor Clank’s Combinator is a 6×3 cascading grid slot with up to 707 ways to pay. Wins are awarded for matching three or more symbols in any row on adjacent reels starting from the leftmost. Marvel at the power of the Combinator from 0.25 to 25 credits per spin. This game has a low volatility rating, a hit rate of roughly 1 in 4 and a 96.10% RTP. Alternative models will be hosted at some casinos, such as a 94% RTP version, and possibly lower.

Violent strings and dramatic chords provide the exciting music that echoes around Professor Clank’s laboratory. Coils charge with bolts of electricity, and electro-mechanical gizmos flash and spark throughout the game. The game is colourful and well crafted in a steampunk style, and the laboratory lights up fully charged during the respin bonus.

The pay symbols start at the low end with 9, 10, J, Q, K and A, awarding from 0.5x to 1.5x your bet for six of a kind. Symbols of a wrench, some goggles, a gun and a robot follow, which pay from 2x to 10x your bet for matching six across the reels.

Professor Clank represents the wild, which does not appear on reels 1 and 6, and substitutes all others except the scatter symbols. An electromagnetic cog acts as the money scatter symbol, which appear with cash prizes up to 2,000x bet and trigger the Bonus Respins for landing five or more anywhere in view.

Professor Clank’s Combinator Slot Features

ReelPlay is not the first developer that springs to mind for cascading games. Known for Infinity Reels and 10K Ways, the budding studio has focused on the two innovative game mechanics, leading to their latest titles, ARRR! 10K Ways and Money Mariachi Infinity Reels, currently headlining casino lobbies worldwide. Licencing agreements have bought more coverage with players’ favourites Relax Gaming borrowing for Tiger Kingdom Infinity Reels. So it’s no surprise that ReelPlay should look to explore further the popular genre of cascading slots with Professor Clank’s Combinator.

Eighteen symbols cascade down to fill each position at the start of a spin sequence. If three or more connect for a win, an explosion removes non-winning symbols and the winning combo drops to the base of the reels and sticks in play. If there is more than one win combination, all symbols from both wins will morph into the highest paying symbol of the two. Following symbol explosions and possible morphs, if a previously winning symbol finds itself in a losing position, the booster feature activates, adding extra matching symbols to surrounding positions to complete a winning combination.

The game then drops a new batch of symbols, one for each reel containing a winning symbol. Non-matching symbols explode, and matching symbols that further the win will stick before triggering a second sequence of explosions, morphs and drops. Money scatters also hold in place but do not count towards advancing the win and will not trigger the sequence. Drops continue until each reel reaches a maximum height of five rows or no symbols match, and the final win combination is paid.

Money scatter symbols can land with cash values of bet multipliers from x1 to x100 or one of four fixed jackpots of Bronze 10x, Silver 50x, Gold 250x and Platinum 2,000x your bet. Land five during a single spin sequence to trigger the Professor Clank’s Combinator Bonus Respins. The bonus starts with the triggering symbols falling to the base of the reels and sticking for the round duration. The reels change to feature money scatters only, and the game begins with a count of three respins.

A single symbol is dropped onto each reel, and if a money scatter lands, it will stick in position and reset the counter to three respins. The bonus continues until respins expire or all of the columns are full. All of the money scatter values are totalled and paid at the end of the feature.

Upon completing the Bonus Respins, you are given a Gamble Feature to risk losing your winnings for an increased amount. You can use a sliding scale to increase your potential winnings. A wheel is split between red and green sections. Landing the pointer in the green section wins the gamble, and landing in red will forfeit your winnings and return you to the main game.

Choosing to gamble for a greater prize will affect your chances of winning. You can choose not to gamble and may collect your winnings at any time. The Gamble Feature may be used up to three times before collecting the payout.

Final Verdict

Professor Clank’s Combinator has an interesting cascading mechanic for adding adjacent symbols and chaining winning combinations to produce lengthy and engaging spin sequences. The hit frequency combined with low volatility maths creates plenty of action without sacrificing maximum win potential, which sits at a healthy 10,000 times your bet. The bonus respins are becoming a familiar sight on ReelPlay titles, of the traditional three spins and out scenario proving popular on modern slots, capable of delivering fine combinations of cash prizes.

The game is well designed, with eye-catching flashes of animation during spins, furthering the advance in the creative finish of ReelPlay, witnessed gradually through their game development over the last couple of years. Professor Clark’s Combinator offers something a little different in a quirky steampunk style for fans of cascading slots and captivating spin sequences, who like plenty of action and a fair hit frequency.
