IQ Test · 5 Mind Games · High-Score Certificates
Measure your mind.
Certify every victory.
Brain Tease Plus pairs a rigorous 40-question IQ assessment with an arcade of five advanced mind games — memory matrices, dual n-back, Stroop reflexes, math surges, and sequence hunting. Instant scores, personal-best tracking, one-tap social sharing, and a personalized downloadable certificate for every achievement.
Five domains. One score.
Each attempt draws eight items per domain from a calibrated bank, weighted by difficulty, so no two sittings are identical.
Logical Reasoning
Syllogisms, deduction, and inference — following premises to what necessarily holds.
Numerical Reasoning
Number series, ratios, and quantitative problem solving under time pressure.
Verbal Reasoning
Analogies, vocabulary precision, and relationships between words and ideas.
Spatial Reasoning
Mental rotation, geometry, and reasoning about objects in space.
Pattern Recognition
Abstract sequences and structural rules — the core of fluid intelligence.
The Mind Games Arcade
Five advanced challenges built on real cognitive science — working memory, interference control, mental math, and fluid pattern reasoning. Every game tracks your personal high score and issues its own downloadable certificate.
NEON MATRIX
A grid of tiles flashes for one second — then goes dark. Recall every position as the grid grows and the flashes multiply.
DUAL PULSE
Dual n-back — the working-memory challenge used in cognitive research. Track positions and colors N steps into the past.
STROOP STORM
The word says CYAN — but it's painted magenta. Beat your brain's own interference reflex in a 60-second storm.
MATH SURGE
Chained mental arithmetic that adapts to you — every correct answer raises the voltage. 90 seconds on the clock.
SEQUENCE HUNTER
Squares, primes, interleaved series, letter ciphers — deduce the rule and strike the next term before time runs out.

Frequently asked questions
How is my IQ score calculated?
Every item carries a difficulty weight. Your weighted performance is converted to a z-score against a reference distribution and mapped to the deviation IQ scale (mean 100, SD 15), with per-domain sub-scores shown alongside.
Is this a clinical IQ test?
No. Brain Tease Plus is a serious, carefully constructed online assessment for educational and personal-insight purposes, but it is not a substitute for a clinically administered instrument such as the WAIS delivered by a licensed psychologist.
What makes the mind games "advanced"?
They're built on tasks used in cognitive research rather than casual puzzles: Dual Pulse is a genuine dual n-back working-memory protocol, Stroop Storm measures interference control, Neon Matrix taxes visuospatial memory span, Math Surge adapts its difficulty to your streak, and Sequence Hunter generates fresh pattern-deduction problems every round. Each one tracks your high score and awards a personalized certificate.
Can I retake the test?
Yes — as often as you like. Each sitting draws a fresh randomized selection from the question bank, and every attempt is kept in your score history with its own certificate.
Where is my data stored?
Entirely on your own device. Your account, scores, and certificates are stored in your browser — nothing is transmitted to a server.
