Professor Clank’s Combinator Review

When a slot has a “professor” word in front of its title, it’s common to expect a wacky ride in an experimental lab somewhere far away. Reel Play and Yggdrasil have come up with something different in the Professor Clank’s Combinator slot. It’s a low volatile game that runs on a steampunk engine with up to 707 ways to win. The RTP is set to 96.10% which is unusual for a low volatile game, so this lab experiment could provide some interesting results.

Yggdrasil is known for its incredible game visuals and rewarding gameplay features. All of that is on display in Professor Clank’s Combinator, where you’ll combine matching symbols with various modifiers for ground-breaking wins. A Stacking mechanic is at the core of it all, raising the number of winning ways and offering wins up to 10,000x the stake.

If you’re in for a crazy wild lab ride, you can play Professor Clank’s Combinator in the most popular online slot sites for free or for real money.

Professor Clank’s Combinator Slot Paytable and Symbol Payouts

Reel Play and Yggdrasil have collaborated numerous times before and the results have been incredible. Professor Clank’s Combinator is no exception. This is a visually stunning slot game with a bit of an unusual grid, but it’s easy to understand. The action takes place in Professor Clank’s lab on a 6x3 grid with a unique winning mechanic.

The steampunk robot is the highest-paying symbol. It pays 10x for 6 on a line. There are four premiums in total joined by a four-set of steampunk card royals. The professor is the Wild and doesn’t appear on columns 1 or 6. A steampunk gearshift is the Scatter, and you need 5 or more of these to trigger the slot bonus.

How to Play the Professor Clank’s Combinator Slot

The default bet in the Professor Clank’s Combinator slot is £1, but you can set it between €0.20 and €20. You can see that the slot has a pretty easy learning curve. All the controls are on the right including the guide that helps you understand how the game works and provides information on the symbols.

In the base game, you get paid for 3-6 symbol combinations. The Wild doesn’t hold value on its own, but it does substitute for other symbols in winning combos except for the Scatter. With a variable reels engine, every win triggers a cascade that will go on and on until a no-win combination occurs.

Unlike in Megaways slot like Gonzo’s Quest Megaways, symbols drop and cascades come with a twist. Whenever a winning combination occurs, all non-winning symbols are removed except for Scatters. The remaining symbols will drop down to the bottom of their respective columns. Now, if after the explosion more than one type of symbol remains (aside from the Scatter or Wild), they morph into the highest-paying symbol on the grid.

Boosters in the form of extra-matching symbols will also be added to surrounding columns if winning symbols are not in a winning position after an explosion. If the columns are less than 5 symbols in height after an explosion, a random symbol is dropped on top once the Morphs have played out. If it results in a win, it stays on the reels. If it doesn’t it explodes with scatters left on the grid.

Once everything has played out, Professor Clank’s combinator does the calculations and pays.

Professor Clank’s Combinator Slot Free Spins Bonus

Five or more Scatters get you to the Bonus Respins round. Before the round begins, all symbols aside from Scatters are removed from the grid. The Scatters drop to the bottom when you get 3 respins, with new symbols dropped on each column.

New Scatters are locked in place when they land and reset the tally to 3. This is a familiar Hold&Respins round, but with special jackpots in tow of which the biggest one (Platinum) pays 2,000x.

When the bonus feature ends, you can gamble your wins up to 10x. You have the option to gamble only half of your wins. Gambling is done up to 3 times, but be way, as you might lose it all.

Professor Clank’s Combinator Slot FAQ

Who developed the Professor Clank’s Combinator slot?

The Professor Clank’s Combinator online slot was developed by Reel Play for Yggdrasil Gaming. Yggdrasil is one of the biggest studios in the online gambling industry, renowned for its fantastic visuals paired with rewarding gameplay features and massive winning potential.

Is Professor Clank’s Combinator a highly volatile game?

No, it isn’t. As a matter of fact, it’s a low volatile game that’s pretty interesting considering the gameplay mechanics and various modifiers. There are even jackpots in the mix. However, don’t expect to hit the big wins right away.

What’s the Professor Clank’s Combinator slot’s RTP?

The RTP is set at a solid 96.10% for a game of low volatility. We can safely say that it’s on point, delivering frequent smaller wins and the occasional big one if you’re lucky to land Scatters and Morph symbols in the Respins Round.

Is Professor Clank’s Combinator a Megaways slot?

The cascades might lead some to think that the Professor Clank’s Combinator slot runs on the Megaways engine. It isn’t so, but it does put a twist on the cascades which results in bigger and more exciting wins. Put some safety goggles and watch those explosions blow things out of proportion.

How does the Cascading feature work in Professor Clank’s Combinator?

The cascades work just like you’d expect them, but with a few twists. Scatters are not removed from the grids, and those explosions can increase the ways to win and boost the slot’s winning potential. The slot will also drop random symbols to give you better-winning chances while symbols morph to the highest-paying premium for big wins.

Is there a Free Spins Round in the Professor Clank’s Combinator slot?

No, there’s no Free Spins Round in the latest Yggdrasil title. However, there is a Respins Round that can pay just as nicely. It starts with 3 respins and is triggered by five or more Scatters. Land Scatters during the Respins to reset the tally and cross your fingers for many cascades that can deliver the biggest wins.

Can I hit a jackpot in Professor Clank’s Combinator?

Yes, there are four jackpots to win in the Respins Round. To land them, you’ll have to land the respective Jackpot Scatters. Those are bronze, silver, gold, and platinum, each one worth 10x, 50x, 250x, and 2,000x respectively. Not the biggest prizes but still overall a great value.

How to use the Gamble feature in the Professor Clank’s Combinator slot?

The Gamble feature becomes available when you finish your Respins run. At that point, you get the option to gamble your wins and boost them up to x10. You can gamble 3 times in a row at max, but be careful, as it’s a 50/50 chance.

Which slots are similar to Professor Clank’s Combinator?

If you’re looking for other mad scientists’ experiments, you shouldn’t skip Rick and Morty Megaways by Blueprint Gaming. You can also try The Wild Machine by Pragmatic Play or Dr. Wildshock by Gold Coin Studios. Play’n GO’s Reactoonz universe is also a good idea.
