The Ninja Slot

In today’s world of online casino games, one can stumble upon loads of projects dedicated to renowned TV series and famous movies. It shouldn’t surprise anyone, because casino operators tend to attract more playing audiences, and film-based slots, for example, are a great suit. But there is a national factor online gambling platforms and software providers utilise to hook thousands of punters. Those slots that hinge on traditional moments can also stand a casino in good stead. Take the Ninja slot, for instance.

As you might have guessed, the topic of our review is Japanese culture and ninjas in particular. These people represented warriors, whose specialization was assassinating victims during the samurai era. ‘Shinobi’ is another way of calling ninjas. This name stands for those who ‘act in stealth’. Nevertheless, it wasn’t the same honour a ninja was credited with due to unconventional methods they used:  forgery and deception.

But enough of history. Let’s hit the ground running and outline the kernel of the slot game as well as the bonus features it offers to gamblers.


The Ninja machine constitutes an online slot game with 5 reels and 25 winning combinations. Released in 2015, the slot’s theme is closely connected to the glorious time of Japanese warriors, namely ninjas. These were cover agents that were well-prepared for every mission. Thanks to the Endorphina software provider, one can enjoy astonishing visuals and sound effects, which take players to the fabulous world where ninjas used to practice martial arts and other exquisite techniques. All playing symbols on the reels epitomise ninja’s attributes. Ninjas themselves are playing icons too. 

An amount of 1,000x the bet is the jackpot in the slot game. Each player can wager as minimum as 0.01 coins to start spinning colourful reels. The Return-to-Player ratio stands at 96%, which is a pretty decent figure for slots. Being a low volatility machine, reels feature plenty of smaller winnings. 

The slot game operates identically on mobile devices as on desktops and laptops. To be fair, all brand new slots work the same on every gadget. So, enjoy claiming real money prizes on iOS and Android smartphones. A free games feature is also available for inexperienced newcomers. Therefore, you can gain an empowering experience playing a demo version.

Without special symbols and offers, no one will start playing a slot machine. The game proposes wild symbols together with a scatter. Free spins and gamble are two features aimed at boosting your bankroll. 

Software Provider

 The Endorphina software company represents a popular provider of games for online casino operators. It has been devising and powering various game projects for 9 years now. The provider has already established itself as an acclaimed name in the gambling industry thanks to their second-to-none slot machines with enthralling design and fancy bonuses. 

Endorphina offers a fully-fledged slot experience with innovative 3D visuals. And having close partnerships with Poolo and XIN Gaming, the influence of Endorphina slots on the world gambling market has been increasingly amplifying. 

Endorphina creates solely video slots. Each product of the company offers advanced bonuses and an exciting playing atmosphere. Their games are flash-based, so you can enjoy spinning reels on mobile devices. The ITech auditing company constantly tests the Random Number Generator technology so as each game delivers fair outcomes.

Speaking of a license issue, Endorphina belongs to the European Union. The Malta Gambling Authority issued a gambling license for the provider in 2018. 


The layout in the game is a 5×3 grid with reels numbered from left to right. In order to get a multiplier, a player should land no less than 3 identical symbols on the reels. The more icons you land, the higher is a multiplier. 

Prior to spinning the reels, each punter has to alter their wagers. By clicking on the ‘Coin’ button at the bottom of the playing field, you can set a coin size from 0.01 to 5. The ‘Bet’ button sets how many coins per line a gambler wants to bet. The number of playing lines is set by ‘Lines’. Finally, you press ‘Spin’, and a feast begins. And one more thing: the ‘Auto’ button can set the reels in automatic motion for as long as a player wishes. 

Playing Symbols

There are no classic picture card symbols in the game. Once you have opened the Ninja slot, you will observe 3 base game ninja symbols together with some attributes like dojo and nunchakus. For example, the slot pays out 40x the wager for successfully landing 4-of-a-kind nunchakus. Other low-paying symbols include:

  • Throwing stars
  • Razor-sharp claws
  • Takko-gaki.

Away from that, the red, yellow and blue ninjas all form the highest paying icons in the slot machine. They pay 25x and 50x multipliers respectively following a 5-of-a-kind combination with 25 active paylines. 


You won’t find separate wild and scatter symbols here, as the Black Ninja rules everything. The Scatter substitutes for all playing symbols in the casino game. These symbols pop up on the reels in random order. More than that, once at least 2 black ninjas appear on the playing field, you can accumulate Wilds – one Wild for one ninja icon. The symbol acts as the Wild if you get only 1 black ninja. 

Once you are lucky enough to land 3 or more black ninjas, the game will activate free spins sessions. How many spins you get depends on the number of accumulated wilds. Once you start playing free spins, the slot will place your wilds on all of the reels except for the first. After the Wild appears, the value of the accumulator goes down in value. You can play free spin games until all accumulated wilds have been used. Besides, there is a special meter that outlines the number of wild icons in your possession. When you decrease the overall bet, the number of wilds is increased. 

Bear in mind that with the Gamble feature all your winnings could be doubled. The bonus game offers a player one face-up card and 4 cards face-down. Then you may reveal any of the 4 cards, and if its value is higher than your initial card, you lose. Otherwise, all winnings get doubled.

Advantages and Disadvantages

Let’s clarify the pros and cons of the Ninja Slot game.

  • Decent RTP ratio
  • Unique theme based on Japanese ninjas
  • Wilds, Scatters, bonus games and free spins at hand

In Conclusion 

Summarising, the slot is a unique game for fans of Japanese culture. Catchy sounds and lovely design add to high game standards. And with free spins and gamble rounds, nothing stands in your way to enjoy impressive real money wins. Play the Ninja slot and enjoy an overwhelming world of these ingenious warriors.
