training notes
reaction board with click tests, typing drills, memory work and aim practice.

every mode gives you 3 attempts. best values and scores are saved locally in your browser. choose a difficulty first, then run the set.
Mode Guide
Classic
Wait for the signal to turn green, then click immediately. Clicking early counts as a false start and restarts the round.
easy: 1-2 sec wait | medium: 1.5-2.5 sec | hard: 2-3.5 sec
Focus
Hold steady through the delay, then react when the prompt appears. Built to punish drifting attention.
easy: longer readable window | medium: shorter alert window | hard: tighter timing and less forgiveness
Visual
One tile is different. Find it before the round times out.
easy: 6 circles total, 15 sec | medium: 9 circles, 10 sec | hard: 12 circles, 6 sec
Mental
Solve the shown math problem and choose the correct answer from four options.
easy: basic math, 20 sec | medium: multiply and square patterns, 10 sec | hard: heavier problems, 5 sec
Memory
Memorize the number sequence, then enter it back using keyboard keys 1-9 or the on-screen buttons.
easy: 3 numbers, 3 sec view | medium: 4 numbers, 2 sec view | hard: 5 numbers, 1 sec view
Chat
After a 3-second countdown, a short message appears. Type a reasonable reply and press Enter.
easy: 20 sec | medium: 10 sec | hard: 5 sec
Typing
A phrase appears after a 3-second countdown. Re-type it exactly and send it before time runs out.
easy: shorter phrases and more time | medium: balanced phrases | hard: longer phrases with tighter windows
Speed
Fast recognition drill. Hit the matching text target as quickly as you can during the round.
easy: fewer options and slower pace | medium: denser board | hard: faster decision loop, more pressure
Tracking
Pure cursor control. You get a 3-second prep, then the target starts moving. Stay on it and build track time.
easy: larger target with calmer path | medium: faster movement | hard: smaller and faster. best result = longest track time, not reaction
Target Burst
Timed burst drill with a 3-second prep. Green target = point. Missing the target counts as a false start. Hard mode also adds a red no-shoot target.
easy: 15 sec | medium: 12 sec | hard: 10 sec. score = total hits in the session
Micro Adjust
Small targets spawn close to center so the drill trains tiny corrections instead of large flicks.
easy: larger dots and wider timing | medium: smaller dots | hard: tiny dots and shorter windows. score = total hits
Target Switch
Two targets appear together. Clear both quickly to score one completed pair.
easy: bigger pair with more time | medium: tighter window | hard: smaller targets and less time. score = completed pairs
Controls
Space = click in Classic
1-9 = enter sequence in Memory
1-4 = pick answer in Mental
Enter = submit in Chat and Typing
ESC = close the active test

scores stay saved in localStorage until you clear them from the main screen
