The N-Back Challenge is a free Android game developed by Rivuspurus that offers a unique type of cognitive training called "dual n-back." Backed by scientific studies published in top peer-reviewed journals, this game aims to help you raise your IQ in just a few minutes per day. The training is designed to be maximally exhausting, but if you can make it through 20 sessions, you may reap powerful benefits.

Intelligence is crucial for learning, reasoning, problem-solving, and making connections. Higher IQs have been linked to improved academic achievement, professional success, and better health. The N-Back Challenge takes just 7 hours to complete, making it a worthwhile investment of your time.

The app aligns with scientific research and allows you to track your progress visually, build up streaks, and compare yourself with other learners. You can compete against friends on leaderboards based on completed sessions and streaks. The app also offers customization options, such as choosing different voices and languages, turning on notifications, and adjusting timing and game speed. If you're busy, you can switch to the Weekly Habit mode, which gives you a full week to complete each session.

Whether you're a parent looking to give your children an edge at school, a grandchild wanting to help older relatives fight cognitive decline, a knowledge worker seeking to boost productivity, or a teacher preparing students for a changing world, the N-Back Challenge can be a valuable tool.
