Clinical-grade brain training built on 40 years of cognitive neuroscience. Used by Dr. Donalee Markus with concussion and traumatic brain injury patients, NASA scientists, and corporate executives since 2003. Strong Mind Mazes is not a casual puzzle game. It is a hierarchical cognitive-restructuring exercise designed to engage neuroplasticity through deliberate, progressive challenge. The same approach featured in Clark Elliott's "The Ghost in My Brain." WHAT IT TRAINS • Concentration and sustained attention • Working memory and mental manipulation • Multi-variable problem solving • Reduced impulsivity through deliberate planning • Carryover skills that translate to daily life THE PROGRAM • 5 hierarchical difficulty levels: Beginner, Intermediate, Accelerated, Advanced, and Expert • Over 1,000,000 maze variations for ample rehearsal • A wide palette of colors, patterns, and graphics that promote engagement without overstimulation WHO IT'S FOR • Concussion and post-concussion recovery • Traumatic brain injury (TBI) rehabilitation • Stroke recovery • Adults seeking cognitive maintenance and resilience • Executives, professionals, and athletes wanting a sharper edge • Used by clinicians as an adjunct to standard rehabilitation THE SCIENCE Effective problem-solving and decision-making are based, at least in part, on the number of variables a problem solver can evaluate at once. With deliberate rehearsal, individuals can learn to increase that number — reducing impulsivity and developing the mental filter that supports planning before acting. This is built on a neurocognitive model emphasizing Attention, Intention, and Rehearsal — three pillars drawn from Dr. Markus's clinical practice and from her post-doctoral training under Reuven Feuerstein, the father of teachable intelligence. ABOUT THE DEVELOPER Dr. Donalee Markus earned her Ph.D. at Northwestern University in 1983 and has been in clinical practice in cognitive restructuring ever since. Her work has been featured in Psychology Today, in Clark Elliott's book "The Ghost in My Brain," and in peer-reviewed publication in Physical Medicine and Rehabilitation Clinics of North America. Institutional clients include NASA, the U.S. Federal Court System, Los Alamos National Laboratory, and Encyclopaedia Britannica.

Dual NBack – Brain Training to Improve Memory Dual NBack is a fun and challenging brain game designed to strengthen your working memory. Set goals, get reminders, and climb the global leaderboards as you sharpen your mind! What Is Dual NBack? Dual NBack is a memory-training game that presents audio (letters) and visual (positions) sequences simultaneously. Research suggests that consistent play may enhance your working memory—the ability to hold and process information briefly—and also boost short-term recall. How to Play The game starts at Level N=2, where you need to remember the position (square) and the sound (letter) from two turns back. If the current position or sound matches what was shown two turns ago, tap the corresponding button. Strong performance automatically raises your level, but you can manually adjust the difficulty whenever you like. Key Features Customizable Settings Tailor your training: tweak the N-value (number of turns to recall), the interval between sounds/blocks, and session length as you see fit. Reminders & Goals Set daily or weekly targets and enable notifications to help you practice consistently. Global Leaderboards Compare your scores with players worldwide and see how you rank as you improve. Share Function Post your results on social media or messaging apps to challenge your friends and family. Multilingual Support Currently offered in English and Japanese, with more languages on the way. Why Train Your Working Memory? Working memory stores information for a few seconds to minutes, enabling you to make decisions, perform calculations, or tackle other cognitive tasks. Playing Dual NBack regularly can help strengthen this mental capacity, potentially improving focus, concentration, and overall brain agility.
