Exercises
Dual N-Back
Track simultaneous visual and auditory sequences. Each session adapts to your capacity, pushing the boundary of what your working memory can hold.
Flash Anzan
Perform rapid mental calculations with visual aids. Enhances calculation speed and accuracy under time pressure.
Mental Arithmetic
Perform multi-step calculations without pen or paper. Builds numerical fluency and strengthens the mental scratchpad used in analytical reasoning.
Sequence Recall
Memorize and reproduce increasingly long patterns. Targets sustained attention and the encoding phase of working memory under mild time pressure.
Pattern Recognition
Identify rules within abstract visual grids. Exercises the reasoning layer that operates independently of prior knowledge — pure problem-solving bandwidth.
The science
Fluid intelligence
Beyond stored knowledge, fluid intelligence is the ability to reason through unfamiliar problems. These exercises are shaped to strengthen that adaptable capacity.
Working memory
Think of it as active mental workspace. Improving working memory helps you hold more variables at once — this matters for mathematics, programming, and strategic reasoning.
Progressive overload
Cognitive training works best near the edge of your current ability. Adaptive difficulty keeps the challenge calibrated so effort stays productive, not repetitive.
