Monsterinos Slot Machine

Do you dare to enter into the mad scientist’s lab in Monsterinos, the online video slot where you could find all kinds of creatures waiting to bid you welcome. 

Created by established developer MrSlotty, you can play on the reels for cash prizes while you keep one eye on exactly what the freaky folk are up to! 

But will you vote this game to be a winner? Here’s a look at Monsterinos by MrSlotty with everything you need to know to play. 

Secret Laboratory

In the laboratory of the mad scientist, the world had no idea what he was up too until he produced the array of crazy creatures on the reels. Your job – if you dare to accept – is to enter into the laboratory and see for yourself just what Monsterinos from MrSlotty has to offer. 

You’ll have no doubt about where you are with green tiled flooring, complete with spooky eyes peering out, a myriad of bottles and test tubes and a bizarre piece of machinery filled with pipes and funnels. 

But the really crazy business is saved for the reels where you’ll see a whole host of mind-boggling creatures….the Monsterinos. 

With bulging eyes, mechanical parts and different creatures fused together, the scientist has really outdone himself this time! But will you be brave enough to stay and play on the reels…facing these ungodly beings in the meantime…?? 

Look Round the Lab

Before you start to play, take a deep breath and explore the laboratory because it's a good idea to understand exactly what you're up against. 

The best place to look is the paytable which can be accessed through a button on the main screen. 

In order to win on Monsterinos you’ll need to match the same symbols together on a winning payline with at least three required to get a prize. However the more symbols you match on a specific line, the greater your prize will be! Some prizes are worth more than others and this too can influence how much you win. 

The prize at the bottom of the paytable is worth just 10 for matching three on the payline while at the opposite end, matching five will ensure that there's a payout of 1,000. 

As well as landing secure symbols there’s some extras on the reels that you might want to look out for. The wild symbol can stand in for others and can help to create wins more easily, increasing the number of prizes you can grab while the free spins symbol will give you up to 10 free turns. 

There’s no progressive jackpot or bonus rounds on Monsterinos. 

Get Ready to Take Them On

Once you’ve finished checking out the lab, return to the reels and prepare to do battle for the riches but don’t forget to check your betting preferences before you do. 

You’ll be playing on 5 reels and there’s 25 paylines you can use but it’s not compulsory to use them all. The buttons at the bottom of the screen allow you to alter the paylines if you would rather play on fewer. 

Having less paylines will decrease the stake but will also lower your chances of a win so it’s up to you to balance the right strategy! 

Another helpful tool is the ability to change the number of coins you bet with; the minimum is one per active line and the maximum is 100 so there’s a lot of flexibility. 

If you’re planning on playing for a long session, give yourself a break and make the most of Auto Play. This spins the reels for you, so you don’t have to keep clicking on every turn. You can decide how many turns you want to set it for, and then simply wait for the prizes to come rolling in. It won’t affect your chances of bagging a win and you can also cancel it at any time with just one click so you’re not tied into using it once you switch it on. You can use the buttons on the right hand side of the reels to increase, decrease or cancel the number of Auto Play spins you want. 

Loopy Lab

Monsterinos offers a very similar play to many of the other online video slots in the library from MrSlotty but thanks to the quirky theme it feels like a different game. There’s some features missing but there’s still good opportunities to win and it's a play that should keep most entertained.
