There are seven basic symbols on Ninja slot and four of them are different kinds of ninja weapons. They have different colors so its easier for the players to distinguish them.

The black ninja is the main symbol of this slot. Each of them can replace any symbol on the reels.

Gamble Feature

Last but not least, as many casino games have, Ninja also has a gamble feature. It works like a card game where the slot has a face-up card and you need to click one of four face-down cards. The idea is to get a better card than the computer. To start it, click on the “Take Risk” button and get a chance to double your winnings. You can double your winnings for up to 10 times but if you make a mistake you lose your initial win.

Thrill Factor

As we mentioned above the black ninja symbol offers a fantastic thrill factor to this slot. Game developers love to add such features and Endorphina certainly did a fantastic job. If you get three black ninjas, the free-game feature will start. In this feature, a ninja appears on the reels and randomly opens wild symbols on the 2nd to 5th reel. The wild symbols he opens are the ones that you have been accumulating the whole time.

Nevertheless, remember that up to 500 wild symbols can be used in a single free-game feature. If you have more, the rest will be kept for the next time you trigger the feature. The wild ninja symbols will give you fantastic prizes which also include free spins.
