Ninja Slot

We take a look at the Ninja slot from Endorphina and discuss the game features that players enjoy the most.

Extremely Popular Video Slot

Released originally in 2015 the game got an update in 2022 with crisper graphics. Admittedly we enjoyed playing this game before the update but the nicer graphics does make the appearance of the slot more appealing.

The Ninja slot uses a 5 x 3 style grid layout of 5 reels and 3 rows in view on the game board. It uses a fixed amount of lines of 20 that are active in play on all spins.

Ninja Slot Theme

Slot machine world lovers will recognize this is not the only game based on ninja’s but this one handles the theme well. Rooted in ancient legend the ninja and secrecy behind who and what a ninja is helps to jeep the mystery alive.

Part of the legend refers to the ninja warrior as a hero that possess special powers and are almost invincible in battle. In the ninja slot game they do have the special abilities to produce large wins for you when matched.

Symbols in the Game

Starting with the premium symbols we have 3 ninjas. There is Blue, red and Yellow with different values. The medium value symbols are the nunchucks, throwing star, hand spikes and hand claws. Each of the medium symbols are various weapons that ninjas might use in battle to gain an edge on their opponents.

You can easily see the different win amounts on other size wagers at any time by adjusting the bet and viewing the paytable inside the game. Win amounts are based on matches of like symbols on a payline, consecutively left to right.

The Black Ninja Slot Wild

Black ninja symbol is wild. He substitutes for all regular game symbols when on a payline for wins. The black ninja can appear anywhere on any reel on the game board. Collecting wild symbols will add up on the wild accumulator from each spin. Landing multiple black ninjas on a single spin will add additional amounts to the accumulator as follows:

  • 2 black ninja symbols will add 2 wild symbols.
  • For 3 black ninjas you gain 5 wild symbols.
  • Land 4 black ninjas and gain 30 wild symbols.
  • 5 Black Ninjas will accumulate 100 wild symbols.

A single black ninja symbol is not added to the accumulator and acts as a regular wild and can only substitute on payline wins.

Wild Accumulator

The wild accumulator is a special meter and accumulates wilds counts after each spin. Wilds count on the meter are based on bet amounts, so when you change the bet size the totals reflect wilds landed for only that bet amount.

Free Games with Black Ninja Feature

When you land 3 or more black ninja symbols anywhere on the game board you get free spins.

Black Ninja Feature Round Explained

During the black ninja feature round, the warrior in black will appear at the end of a spin. He will then attack some of the symbols changing them in to wilds to increase your win amounts. If black ninja hits on on a weapon symbol a regular wild appears, if he hits a ninja icon it changes to an X2 multiplier.

During this bonus round the number of wilds is determined by how many black ninja symbols you ave on the accumulator for that size bet. The round continues until you have exhausted black ninja;s from the accumulator.

Gamble Option

Like most Endorphina slot games you can risk regular match wins with the gamble feature. You can win double or nothing on the win.

There are 5 cards dealt with the first card as the dealers face up. You pick a remaining card, if you beat the dealer you win double, if you lose you lose the initial win amount. A joker is a draw with no loss or win. You can take this risk up to a total of 10 times.

Bonus Pop

At any time between spins you can purchase a bonus round. This will immediately award you the free games with black ninja feature round.

The cost is based on the bet amount and you have a choice of adding 50 or 100 extra wild symbols to the current accumulator amount on the meter for that bet size.

Slot RTP Average

This slot is rated with an average RTP of 96.02%.

Wager Amounts

Minimum wager amount per spin is set at €0.20 since the paylines are fixed at 20 with a coin size of €0.01. Fortunately you can change the coin size and number of coins if you like. The maximum per spin amount is set at €40.00.
