Free browser-based cognitive games that measure attention, memory, executive function, and processing speed. No sign-up required.

Cognitive Flexibility

ABBA Task

Switch between two response rules under time pressure and track how efficiently you adapt to rule changes.

Cognitive Flexibility
Processing Speed

Reaction Time Test

Measure simple visual reaction time — how quickly you detect a green signal and commit a motor response across multiple trials.

Processing Speed
Executive Attention

Flanker Test

Respond to a center arrow while distracting flanker arrows compete for your focus, measuring executive attention and interference control.

Executive Attention
Working Memory

Digit Span Test

Hold digit sequences in memory and repeat them forward and backward, testing verbal working memory span and active manipulation.

Working Memory
Visual Working Memory

Chimp Test

Remember where numbered tiles were, then tap masked positions in ascending order — a classic test of visuospatial working memory.

Visual Working Memory
Cognitive Control

Stroop Test

Name the ink color while ignoring the written word to measure cognitive control and resistance to automatic reading interference.

Cognitive Control
Visuospatial Working Memory

Corsi Block Test

Repeat spatial sequences by tapping blocks in order, measuring your visuospatial working memory span through increasing difficulty levels.

Visuospatial Working Memory
Response Inhibition

Go/No-Go Test

Respond quickly to Go signals while withholding responses to No-Go signals, measuring response inhibition and impulse control.

Response Inhibition
Visual Pattern Memory

Visual Memory Test

Study a grid of highlighted squares and recreate the pattern from memory as grid size and target count increase.

Visual Pattern Memory
Working Memory Updating

N-Back Test

Continuously compare current stimuli to items from N steps back, measuring working memory updating from 1-back through 3-back difficulty.

Working Memory Updating
Fluid Reasoning

Raven's Progressive Matrices

Infer abstract visual rules from pattern matrices and select the choice that completes the underlying relationship.

Fluid Reasoning
Cognitive Flexibility

Trail Making Test

Connect numbered circles in order (Part A) then alternate between numbers and letters (Part B) to measure cognitive flexibility.

Cognitive Flexibility
Visual Discrimination

Color Discrimination Test

Detect the subtly different swatch within a grid of similar colors across 12 rounds of shrinking hue differences.

Visual Discrimination
Divided Attention

Multiple Object Tracking

Track several moving target objects among identical distractors, then identify the original targets after motion stops.

Divided Attention
Verbal Episodic Memory

Verbal Memory Test

Distinguish new words from words seen earlier in the sequence, measuring verbal episodic recognition memory under increasing interference.

Verbal Episodic Memory
Decision Speed

Choice Reaction Time Test

Select the correct response as the number of choices increases from two to four to six, measuring decision speed under response competition.

Decision Speed
Executive Function

2-Stage Decision Task

Complete two sequential decisions per trial — categorize a stimulus then make a follow-up choice based on the first outcome.

Executive Function
Pattern Recognition and Fluid Intelligence

2nd-Order Rule Acquisition Task

Learn hidden same-or-different rules from feedback as a new rule pair is drawn each block, testing rule induction and pattern recognition.

Pattern Recognition and Fluid Intelligence
Impulse Control

Delay Discounting Task

Choose between smaller immediate rewards and larger delayed rewards across 5 adjusting trials per block to estimate your delay discounting rate.

Impulse Control
