Tests & Scoring
What does each test measure?
Reaction Protocol measures your response time to visual and audio stimuli. Aim Assessment tests hand-eye coordination with static and moving targets. Keystroke Test measures your typing speed in WPM and accuracy. Mouse Control evaluates cursor precision and click speed. Rhythm Sync checks your internal timing accuracy. Cognitive Review tests spatial reasoning, memory, and estimation abilities.
How are scores calculated?
Each test uses its own scoring formula. Reaction time is measured in milliseconds (lower is better). Typing is scored in words per minute with accuracy penalties. Aim and mouse tests use accuracy and speed metrics. Rhythm tests measure timing deviation from a perfect beat. Scores are stored per test category and aggregated into a combined Lab Score for the global leaderboard.
Can I retake a test?
Yes, you can retake any test as many times as you like in free-play mode. Only your best score per test category is used for the leaderboard. The Daily Challenge is the only exception — one attempt per day.
How is the Lab Score calculated?
Your Lab Score is the sum of your best score in each test bucket. The more tests you complete, the higher your potential score. Only your personal best in each category counts, so there is no penalty for retrying.
Multiplayer & Duels
How do I play with friends?
Go to the homepage and click "Create Party". You will get a shareable code. Send it to your friends, and they can join by clicking "Join Party" and entering the code. Once everyone is ready, the host starts the game.
How does Duel mode work?
Duel mode uses Elo-based matchmaking to pair you with a player of similar skill. You both race through the same set of tests in real time. Winning a duel increases your Elo rating; losing decreases it.
What is Elo?
Elo is a rating system originally developed for chess. It estimates your skill level based on match outcomes. New players start at a baseline rating, and it adjusts after each duel based on the rating of your opponent. Beating a higher-rated player gives a bigger boost than beating a lower-rated one.

Why is my score not saving?
