Not Enough Kittens from Thunderkick: Slot Review - the cat's meow of slots!

Visit a science lab at the P.U.S.S facility to meet a nutty professor who is looking after a bunch of adorable kittens.

Cats are adorable furry creatures that are pets in millions of homes all across the world. These feisty felines usually go where they like and always have a hint of mischief in their eyes. Top software developer Thunderkick decided to release a slot all about these adorable mammals but a takes place in a scientific laboratory! The lab is run by Professor Catarina Kettingur who is the head of the Science department in a facility aptly called P.U.S.S. Let’s see what the nutty professor is cooking up for these cute little animals and I just pray that it’s just some tins of cat food!

Not Enough Kittens is a 35 payline slot that includes Double Symbols, Stacked Wilds, and Free Spins.

Special Features

The first thing I noticed when playing this game is that the cat symbols can appear as single cat symbols or double cat symbols on the reels. Double cat symbols basically count for 2 symbols but in one position so make sure to try to land as many of these as possible when spinning the reels!

The Wild symbol is represented by a big pixellated disc with the letter ‘W’ displayed inside of it. Like traditional Wild symbols, it substitutes for all other symbols except for the Scatter symbol to form winning combinations on the reels. An interesting feature of this symbol is that if it is part of a winning payline then the Wild will double the value of any wins containing a cat symbol. Also, if you manage to land 10 Wilds on an active payline then you’ll be grinning like a Cheshire cat with a fantastic payout worth 100X your original wager!

The Scatter symbol is illustrated by a catflap door with a pink letter ‘F’ inside of it. Land 3 or more of these symbols in any position on the reels and you’ll trigger the Free Spins bonus game. It goes without saying, the more Scatters you land then the more Free Spins you’ll be awarded. For example, 3 will give 10 Free Spins, 5 will give you 20, and 6 Scatters will give you a nice haul of 25 Free Spins. Land 3 more Scatters while in this feature and you’ll retrigger even more Free Spins. It is actually possible to land 50 Free Spins in total. A neat feature of the bonus game is that all Wild symbols come stacked which should greatly enhance your chances of landing a big payout.

Theme, Graphics and Sound

The graphics are colourful and visually very impressive as the game is set inside Professor Catarina Kettingur’s lab as she stands on top of the reels turning levers and knobs to make the kittens move up and down. Symbols are full of detail and colour and consist of a variety of different cats such as Siamese and Black and White cats as well as a few different coloured balls of yarn. The animations are smooth as symbols move nice and slowly on the reels and the cats blink their eyes and playfully move about in their baskets as they appear on the reels. I particularly liked how the reels are covered in a pink cloudy sky whenever you trigger the Free Spins feature. It's a really neat touch to separate it from the main game.

The music is gentle and feels a bit like elevator music with lots of piano sounds and plenty of kittens meowing! It complements the cat theme of the game nicely.

Win lines, Payouts and Jackpots

The game has 35 paylines, a reasonable RTP of 96.1%, and a maximum payout worth 3,650X your initial wager.
