Ninkai Incident, developed by VJOY Global, is an Android-based free-to-play idle card game that puts you in the shoes of a ninja. The game offers a wide range of famous and powerful ninjas that make your journey easier. Your primary goal is to cultivate your ninjas and form teams to progress through the game.

One of the game's primary features is its element-based system, where elements counter each other, and matching skills can get you better results. Therefore, forming a team that depends on your opponent's elements is critical. Additionally, the game has a trial system where you can grab treasures, but the risks are high, and only the strongest can get the loots.
