Professor Clank’s Combinator Slot Review

Professor Clank's Combinator - Slot Overview

As soon as I fired up Professor Clank's Combinator, I was dropped into a steampunk workshop full of pipes, tesla coils and chugging machinery. This ReelPlay slot runs on 6 reels with 3 to 5 rows and up to 707 ways to win, built around a streak winning symbol accumulation system. Wins trigger Explosions, Morphs, Boosters and Drops, so the same spin can keep stacking up prizes before the reels finally reset.

When I looked past the theme, the numbers made sense for a relaxed grind. The game uses low volatility with an RTP of 96.1 percent and a hit frequency of 24.5 percent, while still packing maximum wins of 10000 times the bet. Wilds, reversed cascades, Bonus Respins with fixed jackpots, a post-bonus gamble option and, for non‑UK players, a 50x bonus buy keep Professor Clank's Combinator feeling packed with action.

Professor Clank's Combinator Slot Information

In Professor Clank's Combinator I can stake from 0.25 up to 25 per spin, which feels well suited to low and mid stakes play. The 6 reels shift between 3 and 5 rows, giving between 243 and 707 ways to win, with combinations formed by landing three or more matching symbols on adjacent reels from the left. That structure works hand in hand with the reversed cascades, as winning symbols always stay on the screen.

Symbols in Professor Clank's Combinator

The paytable in Professor Clank's Combinator looks quite top heavy, so I always keep an eye out for the premium icons. At the lower end you have 9, 10, J, Q, K and A, worth between 0.5 and 1.2 times the bet for six of a kind. High paying symbols show a wrench, goggles, ray gun and robot, where six of a kind pay from 2 up to 10 times the stake.

The wild symbol shows Professor Clank himself and lands on reels two to five only, substituting for all regular pay symbols to complete or extend wins. The bright blue gear is the scatter and behaves differently from other icons during the feature sequences, as it never blows up with the losing symbols. Once I stack at least five scatters on the grid, Bonus Respins start and every scatter carries a fixed cash prize or jackpot.

Explosions, Morphs, Boosters and Drops in Professor Clank's Combinator

In the base game of Professor Clank's Combinator, the real fun starts once a winning way hits. Instead of classic cascading reels, the slot uses what ReelPlay call Explosions. All losing symbols vanish, while the winning ones fall to the lowest positions on their respective reels and stay locked. Scatters stay as well, ready to be combined later. This reversed cascade often creates a fresh layout that feels primed for extra wins.

Once the Explosions phase has finished, Morphs come into play whenever more than one pay symbol type is left on the reels. All those remaining symbols convert into the most valuable type among them, effectively upgrading the win. After that, Boosters check for any symbol that is no longer in a winning position, then drop one or more matching copies into adjacent spots so that the combination regains its paying status.

The last stage in each sequence is called Drops. Any reel that has fewer than five rows filled receives a new symbol on top after the Explosions, Morphs and Boosters have finished. If that symbol extends or improves the win, it sticks; if not, it disappears straight away, while scatters always stay in place. New Drops repeat as long as the total payout climbs or until every column reaches full height.

Bonus Features in Professor Clank's Combinator

When I land or collect at least five scatters in Professor Clank's Combinator, the Bonus Respins feature kicks in after any remaining Drops finish. Every symbol except the triggering scatters disappears, then those gears slide to the bottom row and I receive three respins. New symbols fall onto any column with fewer than five positions, but only scatters stay once they land, and each new scatter resets the respin counter back to three.

When the respins finally end, all accumulated scatters award their cash values. Regular money symbols pay between 1 and 100 times the bet, while bronze, silver, gold and platinum bonus scatters award 10x, 50x, 250x and 2000x respectively. It plays like a classic hold and win round with stacked prizes. Outside the UK, I can shortcut straight into this feature with a 50x stake bonus buy that guarantees at least five scatters.

Gamble Feature and Professor Clank's Combinator Slot Experience

After a decent Bonus Respins round in Professor Clank's Combinator, I can take a shot at the Gamble feature. Up to three spins on a wheel let me pick multipliers of 1.25x, 1.5x, 2x, 2.5x, 3x, 4x, 5x or 10x, with the chances clearly displayed for each step, such as four in five at 1.25x or one in ten at 10x. I may gamble all or half my win, but one miss wipes the gambled amount.

When I put Professor Clank's Combinator through a couple of hundred spins, I saw plenty of short explosion chains that kept the balance moving without huge swings, which fits the low volatility label. Big hits seemed tied to stacking the robot or landing strong Bonus Respins boards. The overall win cap of 10000x the bet is mainly reachable through the gamble, so I tend to treat it as a high risk extra rather than the main attraction.

Professor Clank's Combinator Slot Verdict

After spending time with Professor Clank's Combinator, I see it as a clever twist on cascading slots that still stays easy to follow. Wins sticking to the reels, morphing into better symbols and being topped up by Drops makes even modest hits feel engaging, while the Bonus Respins give that familiar money symbol chase with jackpots up to 2000x. With gentle variance and solid RTP, it suits sessions where I fancy steady, inventive action.
