Play Dr Reactive's Laboratory for Free

Released by the innovative casino games developer Red7, the reels of the Dr Reactive’s Laboratory slot machine are set against a mysterious machine. The symbols include vials in green, purple, pink, and orange, a thunderbolt, and a strand of DNA. You might also notice a radioactive glowing W which serves as the wild or an Atom complete with spinning electrons which acts as a scatter to cause two unique bonus features.

These symbols will hopefully be everything you need to whip up a win!

One of our favorite things about this slot game is the fact that it uses cascading reels. The developers have also combined this with a cluster pays mechanic. This means that the Dr Reactive’s Laboratory online slot has no paylines! To instead earn a win, you must land at least five matching symbols next to each other. This will trigger the win and cause the vials to explode with a win! New symbols then cascade down to replace those you have lost.

You can bet between 0.20 and 100 credits when playing this slot. This will allow every player to enjoy this slot no matter how they prefer to play. With an estimated RTP of 96.11% and medium-high volatility, you shouldn’t have to wait too long to start seeing wins.

If the cascading reels aren’t enough for you, have no fear! Every time new symbols drop down; you might be able to grab some extra wins! Every new win will count towards an extra “respin” of the room so you could build up multiple wins within one “spin” of the reels. Trigger 5 cascades and you will earn 10 free games while 7 in one turn will grab you 15 free games. You can track the number of cascades you have earned with the green meter to the left of the reels.

Now and then, a wild W might drop onto the reels as you play the Dr Reactive’s Laboratory online slot. This symbol can substitute for all except the Atom. This wild symbol can also have a multiplier of up to 5x attached to it for a great little boost if used as part of a win. In the free games, you can expect wilds of up to 10x. They also won’t explode off the reels if they are part of a win. Instead, they will remain in place throughout all of the cascades.

The Atom symbol is a special scatter which can react with either the lightning bolt or DNA symbols. When landing next to the DNA symbol, it will cause all symbols in the column and row of the DNA symbol (excluding wilds) to explode. When the Atom lands next to a lightning symbol, all the lowest paying symbols present on the reels will explode. The other symbols will of course cascade and you might be able to grab some extra wins.

We loved playing the Dr Reactive’s Laboratory slot machine and our expert reviewers could not help but be reminded of some of the other games they have tried.

The Cluster Pays mechanic will always make us think of Aloha! Cluster Pays by NetEnt. This was the first game to feature this game mechanic. If you have not yet tried this game, you need to give it a play. It has a fun tiki theme in addition to sticky respins and free spins. It might look like a very different game, but you will no doubt find many similarities between it and Dr Reactive’s Laboratory online slot.

The other game we were reminded of was Wildchemy from Relax Gaming. This is another slot that mixes chemistry with cluster pays. The reels are only 5x5 as opposed to Dr Reactive’s 8x8. However, it does have a magical portal which can throw out some random wilds and exploding scatters to shake up the reels. If you enjoyed the theme of Dr Reactive’s Laboratory, you should check out Wildchemy next.

We are certain that the Dr Reactive’s Laboratory slot machine is going to appeal to many players. Even if you do not think you are that scientifically minded, this game is easy to play. The bonuses and the theme work together to create one cohesive game packed with the potential to win! You should give it a spin now to experience these inventive bonuses.
