Reaction Time
Reaction time measures the delay between a visual signal and your click or tap. This challenge uses a random waiting period so you cannot simply anticipate the change.

Reaction time measures the delay between a visual signal and your click or tap. This challenge uses a random waiting period so you cannot simply anticipate the change.
Open challenge →The click speed test counts how many deliberate clicks or taps you can make during a fixed 10-second interval and converts the total to clicks per second (CPS).
Open challenge →The aim trainer measures the time needed to hit a sequence of 30 targets. A lower total time means you moved between targets more quickly.
Open challenge →Typing Sprint calculates gross words per minute from elapsed time and then reports accuracy. A personal-best WPM is recorded only when accuracy is at least 90%.
Open challenge →A group of tiles briefly lights up, then disappears. Your goal is to select the same tiles. Each successful round adds another tile to remember.
Open challenge →Sequence Memory presents a growing pattern one step at a time. Repeat the sequence correctly to advance to the next level.
Open challenge →A number appears briefly and is then hidden. Enter the number from memory. Each correct answer increases the digit count.
Open challenge →This challenge uses conflicting color words and display colors. Your task is to choose the displayed ink color—not the word itself—across 20 rounds.
Open challenge →If you want to compare your own results over time, use the same device, browser, input method, and approximate setup. A mouse and touchscreen can produce different results, as can a high-refresh display and an older laptop.
These scores are designed for recreation and personal competition. They should not be interpreted as clinical, cognitive, medical, hiring, or academic measurements.
Pass 2 scoring
The Lab Performance Score converts each completed challenge personal best to a 0–100 score using fixed internal recreational scoring bands, then averages those completed scores. It is intended to make your own multi-challenge progress easier to follow. It is not a standardized assessment and should not be used to compare health, intelligence or capability between people.
Your activity streak counts consecutive calendar days with at least one completed challenge. Daily Challenge badges count only the challenge selected for that day.
Precision Tracking and Word Memory: higher percentage is better. Reflex Choice and Keyboard Reaction: lower average response time is better. Arithmetic Sprint, Pattern Match and Visual Search: lower adjusted completion time is better. Time Estimation: lower absolute error from 10 seconds is better.
Pass 4 progression
Each tracked challenge now supports Beginner, Standard, Advanced, and Expert settings. Personal bests and recent results are stored separately by difficulty so records remain meaningful within the version of the task you played.
The 0–100 Performance Score continues to use Standard-mode personal bests as a consistent baseline. Completed runs at all four difficulties contribute to a separate local Lab Rank.
