Not Enough Kittens Online Slot Machine – Free Play & Review

Not Enough Kittens is based on the idea that you can’t ever have enough kittens to play with. The entire game is built around this machine that creates kittens out of thin air by the looks of it, and which is controlled by a female scientist. The location isn’t very clear, but it appears to be in the apartment of that woman, as you can see some of her furniture along with the lab equipment.

The symbols are coming in two variants, showing cats or balls of yarn. There are multiple versions for each of those two types, and the cats also have single and double versions for each symbol. The balls of yarn just have different colors and sizes.

It’s a good game graphics wise, but that’s something that is expected of Thunderkick’s releases, so it’s not a surprise.


This company is called Thunderkick and it is a creator of slot machines, a newcomer to the industry which has been doing this for only a couple of years.

With developers that originate from companies like NetEnt, they manage to create some impressive slot machines, and they definitely don’t try to just clone existing games. They offer new themes in their game, like Babushkas or Barber Shop Uncut, and those have proven to be fairly popular with players.

How To Play It

The available bets in this game range between $0.10 and $100. It’s the standard list of bet values that Thunderkick uses in pretty much all their slots. They don’t take into account the number of lines, so you don’t get really have a line bet that’s easy to calculate.

The slot offers 35 active lines on 5 reels. It’s a game that is designed for use on mobile devices, so the interface reflects that and uses a small number of buttons.

Special Features

Slot machines which use double symbols in combinations have become a lot more common lately, and Not Enough Kittens is one such game. Your winning combinations which are formed with high-paying kitten symbols are going to be capable of reaching up to 10 symbols, even though only 5 reels are used.

They do this by taking into account the number of kittens that are shown in the symbols which form combinations. Since symbols can have both single and double variants, you can get paid with anywhere between 3 and 10 cats. The regular symbols continue to have only 3 to 5 positions occupied in combinations.

Wild symbols have single and double variants as well, and so they can contribute better to the high-paying combinations, while also forming their own. They pay some of the biggest rewards of the game, if they happen to have up to 10 W logos in a combo. They are always counted as a Double Kitten, if they contribute to that sort of combo. Also, when a wild symbol is part of a combination, one of the kitten symbols present on that line will be turned into a double kitten, so it improves high-paying wins that it is a part of.

A bonus feature with free spins may be activated in the game, with 3 to 6 logo scatters appearing anywhere on the reels. 10 to 25 free spins are going to be offered, depending on the number of triggering symbols.

Maximum Payouts

There are several symbols that can offer the jackpot of the slot, which has a top value of $10,000, at a wager of $100 per spin.


Not Enough Kittens follows a trend that seems to work for Thunderkick, that of using unusual themes and unique features in their slot machines.
