Aim Trainer

How to play

1. Pick a mode. The 30-second sprint counts how many targets you can hit before time runs out. The 30 targets run measures how long you take to clear thirty of them.
2. Pick a target size — small, medium or large. Small targets demand precision; large ones let you focus on raw speed.
3. Click anywhere in the play area to start. A target appears immediately.
4. Click each target as it appears. A new one spawns the instant the previous one is hit.
5. When the round ends you get your score, accuracy, average time per target, targets per second and an emoji rating. Press 🔁 Play again to go straight into another round.

Every click inside the play area that does not land on a target counts as a miss, so you cannot improve your score by clicking wildly. The live counter at the top of the area shows your hits and misses as you go, along with the time or targets remaining.

Targets are real buttons, so keyboard users can focus the target and press Enter or Space to hit it. On touch devices the play area disables scrolling and pinch-zoom while you are inside it, so a fast tap never turns into an accidental page scroll.

Scoring

The emoji rating is based on targets per second, so it means the same thing in both modes: 🎯 at 1.5 and above, ⚡ from 1.2, 🚀 from 0.9, 🏃 from 0.6, and 🐢 below that.

A worked example. Suppose you hit 30 targets in 28.4 seconds with 6 misses along the way. Your accuracy is 30 ÷ 36 × 100 = 83.3%, your average per target is 28400 ÷ 30 = 947 ms, and your pace is 30 ÷ 28.4 = 1.06 targets per second — a 🚀. Now suppose a second run takes 31 seconds but with only 1 miss: accuracy jumps to 96.8% and the pace drops slightly to 0.97. That second run is the more useful one, because accuracy is the part that transfers to a real game.

Personal bests are stored separately for each mode and target size. A 30-second sprint on large targets and the same sprint on small targets are genuinely different tests, and keeping one record for both would hide your progress on the harder setting.

How the targets are placed

Each round starts from a fresh random seed, which feeds a small deterministic pseudo-random generator. The generator returns two numbers between 0 and 1 for each target, and those are mapped into the play area with the target’s radius subtracted from every edge:

x = radius + fx * (areaWidth  - 2 * radius)
y = radius + fy * (areaHeight - 2 * radius)

That inset is why a target never hangs over the border — the maths simply cannot produce one. The play area keeps a fixed 4:3 shape and fills the available width up to 640 pixels, and target radii scale down with it on narrow screens while never dropping below a 16 pixel radius, which keeps every target comfortably tappable.

There is one more rule: if a newly generated position lands within three radii of the previous target, the generator tries again, up to six times. Without it, two consecutive targets could overlap and the second would be a free click that flatters your score.

Tips to improve

• Accuracy first, always. Set yourself a floor — say 95% — and only push your speed while you stay above it. Speed gained by missing more is not gained at all.
• Move your whole arm for big distances, your wrist for small ones. Trying to cross the screen with wrist alone is how overshooting starts.
• Lower your sensitivity if you overshoot constantly. Most people who miss past the target are running a mouse sensitivity tuned for turning, not for aiming.
• Stop on the target, do not click through it. The instinct to click as you arrive is what produces the ring of misses just outside each target.
• Warm up on large targets. Two rounds on large, then switch to medium. Starting cold on small targets mostly trains frustration.
• Use a consistent surface and grip. Aim is muscle memory, and muscle memory hates a moving mouse pad.
• Do short sessions. Five focused minutes beats thirty minutes of tired clicking, which just teaches your hand bad habits.

Privacy

The trainer runs entirely in your browser. Target positions are generated locally, timing comes from your own device’s high-resolution clock, and nothing about your round is sent anywhere. Your best score for each mode and size combination is kept in this browser’s localStorage so it survives a refresh; clearing your site data, or pressing 🧹 Clear best scores, removes it permanently. There is no account, no leaderboard upload and no tracking of how you play — and the page continues to work offline once it has loaded.
