About Track the Targets
Track the Targets is a visual tracking game. Up to fourteen identical discs bounce around a dark arena, colliding with the walls and with each other. Before they move, a few of them are marked with a gold ring and the letter T. Your job is to keep track of those few while everything moves, then choose them when the motion stops.
Every round is generated from a seed, and the motion is calculated in fixed steps before the round begins, so the same seed and difficulty always produce exactly the same motion on any device. That is what makes the daily five and friend challenges fair: everyone who plays a seed sees the same thing.
How to play
- Choose a mode and, for fixed difficulty, a level, then press Start.
- Watch the discs marked with a gold ring and a T for two seconds.
- After a one-second countdown the marks disappear and every disc moves.
- When the motion stops, number labels appear. Choose exactly as many discs as there were targets, then Confirm.
- The result shows which you got right. Review replays the round with the targets marked.
Controls
- Tap or click a disc after the motion stops to choose it; tap again to un-choose it.
- Or use the numbered buttons under the arena: Tab to the list, arrow keys move between numbers, Space or Enter chooses.
- Confirm is only enabled when you have chosen exactly as many discs as there were targets.
- Pause stops the round; restarting it plays the same round again, marked as assisted.
- In Review, Play and the time slider move through the round. Review never changes a score.
The rules
- Starter has 6 discs and 2 targets for 8 seconds; Easy 8 and 3 for 10 s; Standard 10 and 3 for 12 s; Hard 12 and 4 for 14 s; Expert 14 and 5 for 16 s. Speeds rise from 80 to 190 arena units a second.
- Discs bounce off the walls and off each other like equal billiard balls. Nobody speeds up during a round.
- Score per round is the share of targets you found: 2 of 3 is 67. Choosing a wrong disc earns nothing.
- Hiding the tab, switching window or a long stall stops the round instead of letting it run unseen.
Scoring, saving and limits
Fixed-difficulty bests, adaptive practice and slow practice are kept separately so results stay comparable. A perfect-round streak counts unassisted rounds of 100 in a row. The daily five (one round at each level, chosen by the UTC date) totals up to 500; only your first play of each daily round counts.
Your recent rounds, bests and daily progress are saved in this browser only. Download a backup to keep them or move them to another device; importing a backup is checked first and can be undone. Challenge links hold only the round number and difficulty.
Bests come from your last 100 rounds (a round that holds a best is never dropped). Scores are a record of play on this device, not a verified result, and this game is not an eye test, a medical or cognitive assessment, or a measure of sporting ability.
Accessibility
This activity depends on following movement by sight, so it cannot be made equivalent without vision. Menus, choices and results work with a keyboard and are announced to screen readers; target identity is shown by a ring and a letter, never by colour alone. Number labels are hidden while discs move so the task stays a tracking task. Slow practice reduces the speed and is labelled.
Questions
- Why did my round stop?
- The tab was hidden, the window lost focus, Pause was pressed, or the animation stalled for over a quarter of a second. A tracking round that kept running unseen would not be fair, so it stops and can be restarted as an assisted round.
- Is the same round the same for everyone?
- Yes. A round is fixed by its seed and difficulty; the motion is calculated in fixed steps before it starts, so frame rate and screen size do not change it.
- Does a high score mean better eyesight or reflexes?
- No. It describes how many targets you followed in this game, nothing more.
