This is fun! It’s surprisingly difficult but I feel like it’s doing something good for my brain. Once you get the hang of it, it’s really enjoyable. The best part is figuring out the tricks. It’s a shame it only goes up to level 10. I feel like I could go even further. I want to push myself to the limit. I think it would be great if you could make an infinite version with a nationwide ranking. Please consider it!

This is a great app! I was stuck on level 6 for a long time and thought I’d never be able to beat it, but I kept trying and finally made it. Level 7 and beyond were a breeze.

I downloaded this app to train my 9-year-old son’s working memory. Even as an adult, it’s quite challenging until you get the hang of it! It requires a lot of concentration to clear, so it seems to be effectively training both concentration and working memory. The Famicom-style RPG opening is also really exciting!

Level 10 is insanely difficult.

Have you ever tried an n-back task? While it’s a great way to exercise your brain, it can be quite intense, even leading to headaches. That’s because you’re constantly switching between remembering and retrieving information.
We wanted to create a more enjoyable way to experience the benefits of n-back training. That’s why we developed “Memory Squadron Obol Ranger”. It’s a fun and engaging app designed to help you improve your working memory and emotional control.
Our hope is that this app will make it easy for you to incorporate brain training into your daily routine and live a happier, more fulfilling life.
