The hand-eye coordination test is a Canvas-based game where colored targets appear and shrink — click them before they vanish. Choose from four difficulty levels, track reaction times, and compare scores across sessions. 20 targets per round.
Choose Difficulty
Targets appear on the canvas and shrink over time. Click each target before it disappears. The game ends after 20 targets. Your reaction time for each hit is recorded.

How to Play the Hand-Eye Coordination Test
This hand-eye coordination test measures how quickly and accurately you can click targets that appear randomly on a canvas. Unlike basic reaction time tests, this game also tracks accuracy and provides a letter grade based on your overall performance across 20 targets per round.
Step 1: Choose Your Difficulty Level
Four difficulty levels are available. Easy gives you large 40px targets with 3 seconds each — perfect for warm-up or first-time players. Medium uses 25px targets with 2 seconds each — the recommended starting point for adults. Hard drops to 15px targets with only 1.2 seconds — suitable for experienced gamers or athletes. Expert uses tiny 10px moving targets with 0.8 seconds — designed for top-tier coordination testing. Harder difficulties also award more points per hit (up to 8x multiplier).
Step 2: Click or Tap Targets
Each target appears as a colored circle with a subtle glow effect and a shrinking progress ring showing how much time remains. Click or tap the target before the ring completes. A hit shows a burst effect and floating score number. A miss shows a red X. The game ends automatically after 20 targets have been spawned (hits + misses). On mobile, tap the canvas directly — touch events are fully supported.
Step 3: Review Your Results
After 20 targets, you receive a letter grade (A+ through F) based on accuracy (40% weight), average reaction time (35% weight), and hit count (25% weight). You also see: total score, targets hit, accuracy percentage, average reaction time, best reaction time, and worst reaction time. Reaction times under 250ms are excellent. Under 400ms is good. Over 600ms suggests you may benefit from more practice.
How to Improve Your Score
Focus on accuracy over speed — missing targets resets your rhythm and costs time. Position your cursor or finger near the center of the canvas where targets appear most. On Expert mode, track moving targets with your eye before clicking to reduce misuse miss rate. Regular practice (5 minutes per day) shows measurable improvement within 1-2 weeks. Sports requiring eye-hand precision — table tennis, badminton, squash — also improve these scores significantly off-screen.
FAQ
Is this coordination test free?
Yes, completely free with no signup required. The game runs entirely in your browser using HTML5 Canvas — no downloads, no accounts, no ads between rounds.
What is a good hand-eye coordination score?
On Medium difficulty (25px targets, 2s each): hitting 15+ targets with 75%+ accuracy earns a B grade. Reaction times under 400ms are good. An A+ requires 85%+ accuracy and sub-300ms average reaction time. Expert players (athletes, pro gamers) typically score A on Hard or Expert difficulty.
How many targets are in one game?
Each round is exactly 20 targets. This provides a consistent benchmark for comparison across sessions and difficulties. The game ends automatically after all 20 targets have been spawned, regardless of how many you hit.
Can I improve my hand-eye coordination?
Yes — hand-eye coordination is highly trainable. Racket sports (tennis, table tennis, squash), catching sports (baseball, basketball), and precision video games all improve it measurably. In this test, playing regularly for 5 minutes daily typically shows improvement within 1-2 weeks. Start on Easy, then progress to harder levels.
What affects hand-eye coordination?
Age (peaks in mid-20s, gradually declines), fatigue (especially from screen time or poor sleep), caffeine (modestly improves reaction time), motor skill training, and practice frequency. Athletes and frequent gamers typically have 20-50ms faster reaction times and higher accuracy than sedentary individuals.
Does the test save my scores?
Yes — your last 10 game results are saved locally in your browser (localStorage). The history table shows date, difficulty, score, accuracy, average reaction time, and letter grade. Your personal best is highlighted with a star. No data is ever sent to any server.
What is the Expert difficulty like?
Expert mode uses tiny 10px radius targets that move around the canvas and disappear in only 0.8 seconds. Up to 4 targets can be active simultaneously. Each hit earns 8x more points than Easy. It is designed for serious coordination testing — most casual users will find Medium or Hard more rewarding to improve on.
