# BrainStorm.Place (https://brainstorm.place)

> BrainStorm.Place is a free, scientific cognitive assessment and brain workout platform. Users take timed IQ and aptitude tests across diverse cognitive domains, solve spatial and logic puzzle games (Queens, Sudoku), inspect in-depth performance analytics on a personalized dashboard, and read peer-referenced cognitive science guides.

## Core Cognitive Assessment Domains

- [Pattern Recognition](https://brainstorm.place/test/pattern-recognition): Tests sequence identification, visual analogies, and progressive matrices (Raven's-style matrices).
- [Logical Reasoning](https://brainstorm.place/test/logical-reasoning): Deductive logic, propositional logic, syllogisms, and critical inference analysis.
- [Spatial Reasoning](https://brainstorm.place/test/spatial-reasoning): 2D/3D mental rotation, cube folding, perspective transformations, and visual geometry.
- [Verbal Reasoning](https://brainstorm.place/test/verbal-reasoning): Reading comprehension, vocabulary relationships, analogies, and semantic deduction.
- [Numerical Reasoning](https://brainstorm.place/test/numerical-reasoning): Mental arithmetic speed, number series completion, and quantitative logic.
- [Random Assessment](https://brainstorm.place/test/random): Multi-disciplinary 20-question timed cognitive battery sampling all core domains.

## Candidate & Corporate Assessment Prep

- [Geotab Candidate Quiz](https://brainstorm.place/test/geotab): Targeted aptitude practice for technical candidates.
- [PwC Candidate Assessments](https://brainstorm.place/test/pwc): Corporate-style recruitment benchmark tests covering Numerical Reasoning (18 Qs) and English Language Proficiency (30 Qs) with worked solutions.

## Interactive Brain Games

- [Queens](https://brainstorm.place/brain-games/queens): Chess-inspired logic puzzle. Place N queens on an N×N board such that no two queens share a row, column, color territory, or diagonal.
- [Sudoku](https://brainstorm.place/brain-games/sudoku): Classical 9×9 grid deduction game featuring multiple difficulty levels and real-time validation.

## Performance Analytics & Dashboard

- [Analytics Dashboard](https://brainstorm.place/dashboard): Visualizes cognitive strengths using interactive radar charts across the 5 core cognitive domains, alongside speed vs. accuracy progression tracking.

## Cognitive Science Research & Guides

- [Cognitive Science Blog & Articles](https://brainstorm.place/blog): In-depth articles covering intelligence metrics (WAIS, Cattell-Horn-Carroll theory), neuroplasticity, working memory training, and cognitive assessment preparation.

## Technical Context for AI Agents & Search Engines

- Standard test format: 20 timed questions per assessment.
- Difficulty levels: Easy (includes step-by-step solutions), Medium, Difficult.
- Scoring methodology: Measures both response latency (seconds per question) and raw correctness to benchmark cognitive agility against standardized percentiles.
