What you'll train

8 cognitive domains.
Algorithms, not databases.

Logic & Reasoning
Dominoes, card sequences, Raven matrices, syllogisms. Every question is generated on the fly with a unique hidden rule.
Inductive reasoning
Spatial
Dynamic SVG matrices, geometric shape sequences, space measurement. Shape, fill, size — a logic to decode.
Raven matrices
Mental math
Addition, subtraction, multiplication, calculation chains, equations, time calculation. Speed and accuracy to measure numerical fluency.
Mental math
Memory
Mnemonic grids, Kim's Game, Working Memory, Corsi, prospective memory. Memorize, retain, recall. The cornerstone of fluid intelligence.
Memory span
Language
Letter sequences, semantic analogies, lexical intruders. Verbal richness directly measures crystallized IQ.
Lexicon
Attention & Inhibition
Stroop, Go/No-Go, Flanker, Barrage, visual search. Measures the ability to focus and inhibit automatic responses.
Executive control
Decision & Judgment
Iowa Gambling Task, WCST. Assesses decision-making under uncertainty and cognitive flexibility when rules change.
Executive functions
Adaptive difficulty
Built-in Elo system. Every answer recalibrates your level in real time. Never too easy, never impossible.
