Review summary

User feedback highlights Idle Ninja Online as fun and feature-rich, with lots of missions and a solid upgrade system. However, repeated reports of crashes, login and account problems, and a perceived lack of developer support severely hinder the experience. Some players also voice concerns about expensive in-app purchases. Overall, the game shows strong potential but its stability, account reliability, and ongoing support are the most mentioned pain points.

Pros

Fun and engaging gameplay with many missions and bosses
Rich upgrade and progression system (diverse gear options and shuriken animations)
Idle-style progression that makes it a good time-killer with ongoing content

Cons

Frequent crashes, loading failures, and random app closures (stuck at loading, black screens)
Login/account issues and potential loss of progress (inability to access old accounts, bans, progress loss)
Perceived poor developer support and signals of abandonment (slow or no responses, lack of updates)
Monetization concerns with overpriced premium content and packs

2026-03-07	Bi*****	Game won’t load, tried deleting and reinstalling but still won’t. I have an iPhone 13 plus so I know it’s not because of that, I don’t know if it’s because of the new region and ninjas but there’s no way for me to play this.

2026-01-17	MR*****	I feel like it’s too glitch and if they made a second one including all the old stuff yet maybe just retextering things and even adding a new lv cap it would attract a lot more people than an old game would. This is just a recommendation but I hope they take it into consideration

2025-01-16	Ze*****	I loved the game at first. I was starting to progress pretty far through the game when I woke up one morning and my account has been banned/deleted. No idea why and no explanation given. I have tried to reach out to the devs via social media, email, etc… with no response… The thing that makes me ever madder is I’ve spent actual money on this game only for my account to be banned for no reason whatsoever. Terrible game and even worse devs. I will never be playing this game again due to how the devs are. It’s such a shame because I loved this game prior to all this happening…
