Professor Clank's Combinator Features

There are many modifiers in this slot that can be triggered at certain moments. Firstly, when a winning combination hits, all the non-winning symbols are removed from reels with the ones that remain dropping to the lowest positions. After an explosion, if more than one symbol type remains on the reels, then this will morph into the highest paying symbol.

Any winning symbols after explosions and morphs that are no longer in winning positions add extra matching symbols to one or more adjacent reels. If explosions, morphs and boosters have occurred, then a new symbol drops on the top of each column less than 5 symbols high. All dropped symbols that improve the wins are kept but others explode. Any new symbol win greater than before the drop awards an extra drop.

Finally, the biggest feature in this slot is the bonus respins that are triggered by landing 5 or more scatter symbols. Non-scatter symbols explode and drop to the bottom of the grid awarding 3 respins. Each new symbol resets the respin counter to 3 and holds the symbol on the reels.

This ends when there are no more respins or the screen is full of symbols. There are also fixed jackpots of 10x, 50x, 250x or 2,000x the stake that can be awarded during this feature. Non-Uk players will be happy to know that there is a bonus buy button to purchase the bonus round.

Professor Clank's Combinator Review

There are many legends about the crazy Professor Clank and they all stem from his bizarre experiments. Some say that he is a mad scientist, whilst others say he's a genius - but it's up to the player to decide.

Developed by ReelPlay, Professor Clank's Combinator is a steampunk slot that plays on 6-reels with up to 707 ways to throughout the gameplay. With multiple modifiers and bonus respins, players can soon be winning up to 10,000x the stake in this low volatility slot.


The background of this slot is clearly inspired by steampunk fiction. There are so many old-fashioned machines paired with golds and purples.

On the reels, there are different tools such as wrenches, binoculars and little robots to help the Professor out. The Professor himself is a unique character with a big pink tophat with goggles and a cape on. He definitely stands out as eccentric and bizarre.

As for music in this slot, there are so many instruments playing throughout with drums, violins, cellos, xylophones and guitars leading to something exciting. Thankfully, it works pretty well and doesn't ever get too annoying or off-putting.


There is absolutely no shortage of thrills in this slot with multiple modifiers in the base game and a wonderful bonus round. Thankfully, none of the gameplay is overly complicated either making it perfect for newcomers.

The bottom of the screen contains the spin button and bet level. However, there is also a bonus buy button for non-UK players to purchase the bonus round.

Win Potential

Unbelievably, this slot is a low volatility slot meaning that wins are frequent but small. This is shocking because the maximum win for this slot is 10,000x the stake which is often unheard of in low volatility slots.

This amount can be won through the bonus round and will certainly satisfy players. There is also a decent RTP of 96.10% which is unexpected for ReelPlay.

Our Verdict

Professor Clank's Combinator is an absolute triumph for low volatility slot players. The gameplay is exciting, whilst the design is absolutely brilliant.

There are rarely any low volatility slots that are this exciting and Professor Clank's Combinator sets a new high standard for these types of slots.
