【What Is the N-Back Task?】
Introduced by Kirchner in 1958, the N-back method strengthens working memory by recalling information from “N steps earlier” while making quick decisions.
Abilities expected to improve include:
・Memory
・Focus and sustained attention
・Judgment
・Emotional regulation
Working memory is the mental “workbench” essential for learning, productivity, and daily life.
【Training Design of Memory Rangers】
・Level 1 starts with remembering one step back (beginner-friendly)
・Difficulty gradually increases across 15 stages
・Level 10 is famously tough for those seeking a challenge
・Retro RPG-style presentation keeps the journey engaging
Simple to play, yet you will feel real cognitive challenge as you progress.
【Fun for Families】
One device supports up to 3 profiles, allowing:
・Siblings to compete
・Parents and children to challenge each other
・Friends to enjoy the training together
【Message from the Developer】
N-back is effective but mentally demanding, and many people struggle to keep it going. Still, I believed there were people who wanted to improve emotional balance, focus, and daily well-being.
I wanted to create an experience where
“you were enjoying a game… and before you knew it, your brain had improved.”
That is why I combined the excitement of superhero teams with the warmth of retro games, creating a training method anyone—kids or adults—can continue without stress.
If this app brings even a little more calm, focus, or happiness to your daily life, nothing would make me happier.
