About this game

The N-Back Challenge provides a special type of cognitive training, “dual n-back,” that helps you raise your IQ in just a few minutes per day. Sounds implausible? The N-Back Challenge is based on a decade’s worth of scientific studies, published in top peer-reviewed journals, including Nature. (For more details, see https://nbackchallenge.com/science.)

The catch? It’s no fun at all! Indeed, the training is designed to be maximally exhausting. If you are determined enough to make it through 20 sessions, however, science suggests that you stand to reap powerful benefits.

Intelligence is the ultimate cognitive ability: You need it to learn, reason, solve novel problems, and see connections. Higher IQs have been linked to improved academic achievement, professional success, and even better health. Since it will take you just 7 hours, in total, to complete the N-Back Challenge, not much more than the length of a single school day, it may prove to be the best investment of time you’ve ever made!

------------------------------

SCIENTIFICALLY SOUND: Not only has the dual n-back paradigm been validated in top peer-reviewed journals, but our two founders – both PhDs, one with a focus on neuroscience, the other with a focus on higher education – have taken particular care to thoroughly align the app with the prevailing scientific research.

TRACK YOUR PROGRESS: In order to help you stay motivated, the N-Back Challenge allows you to visually monitor your progress over time, build up “streaks,” and compare yourself against other learners across various stats.

COMPETE AGAINST YOUR FRIENDS: Perhaps the most powerful way of making sure you remain motivated to complete the Challenge is to tackle it together with friends or colleagues. To make it more fun, we’ve provided leaderboards that allow you to compete based on who has completed the most sessions, racked up the longest streak, and more.

CUSTOMIZE YOUR EXPERIENCE: The N-Back Challenge allows you to choose between different voices across multiple languages, turn on notifications, and customize their timing and style. There are advanced settings for turning on instant button feedback, controlling the n-back level, and tweaking the game speed. And if you are too busy to complete one session every day, you may switch to the Weekly Habit, which gives you a full week to complete each session.

------------------------------

ARE YOU…

… A PARENT? Give your children an edge at school or university by nudging them to complete the N-Back Challenge. Indeed, why not tackle the Challenge together as a family?

… A GRANDCHILD? Help your grandparents (and other older relatives) fight cognitive decline by introducing them to dual n-back. (See https://nbackchallenge.com/decline.)

… A KNOWLEDGE WORKER? Share the N-Back Challenge with your HR department. Dual n-back may well be the single most cost-effective way of making knowledge workers more productive. (See https://nbackchallenge.com/work.)

… A TEACHER? Use dual n-back to enhance students' problem-solving skills. You can have a big impact, with a minimal investment of time! (See https://nbackchallenge.com/class.)

------------------------------

HOW IT WORKS: The N-Back Challenge is free as long as you stick to the program. When you miss or delay a session, we ask you to support us with a “coffee,” which you can buy in-app or earn — for example, by using the Share link in the Settings to invite friends. (Each of you will receive a free coffee.) You can also unlock unlimited free breaks by becoming a premium subscriber.

CUSTOMER SUPPORT: Do you have any questions or suggestions? Like to say hello? We’re happy to hear from you! Just drop us a note at support@nbackchallenge.com.

love the simplicity of this game after first playing it but the thing is that when I tried this game it doesn't have the red or green feedback whenever I'm playing which often had me confused if you wanna keep it that way at least add a feedback thingy in the settings because I'm the type of person that needs instant feedback to keep going instead of my result afterwards which is often somewhere 65-72% percentages but still good overall

Hello, thank you for sharing. The instant feedback option is available in the settings: please go to Advanced settings, and you will see it near the top of the view.

I like the concept, however there seems to be a bug where the game flags correct answers as incorrect (at least if I interpret red circle around Position button correctly). I can send you a screen recording to demonstrate.

Hello Andreja, thank you for sharing. Yes, please write to support@nbackchallenge.com, so that we can discuss it in more detail. There have been cases when the rules of the game were not entirely clear, which made it look like the game had a bug. If so, we will clarify them. And if it's indeed a bug, we will be glad to fix it. Thanks!

I started about a year ago and came back to it 15 days ago, I hate when I have to keep coming back to it and keep my steak! it's really challenging. But I love how every time I keep coming back, I Improve everyday! That's what keeps me coming back, even with the frustration! It's a good app and I would recommend it to anyone.

Hi Seth, thank you very much for such honest, detailed feedback! It's very gratifying to know that N-Back makes such a difference in your life that you keep coming back even if it feels challenging and frustrating at times. It's moments like this one that motivate us to keep working on the app. We wish you huge success with your training!
