Blindspot – Red Ball Focus & Object Tracking Test

Blindspot: The Red Ball Focus Test That’s Harder Than It Looks

You’ve probably seen the “follow the red ball” clips going around — a ball turns red, disappears into a crowd of identical white ones, and you’re asked to spot it again. Blindspot turns that viral idea into a real, playable object tracking test, with scoring, difficulty settings, and a live global leaderboard.

How the Focus Test Works

At the start of each round, one or more balls light up red inside a circle of white balls. Everything drifts and speeds up while you watch. Slowly, the red balls fade back to white — by the time the round freezes, your targets look exactly like the balls that were never highlighted. You then have to tap the correct ones purely from memory, with zero visual cues left to guide you.

This is what’s known in cognitive science as multiple object tracking (MOT) — the same category of task used in sports vision training and attention research. It’s a step beyond a basic reaction time test, because speed doesn’t help you if you didn’t actually memorize which balls mattered.

What Makes This Different From a Reaction Time or Aim Trainer Test

Most browser “brain test” sites — reaction time checkers, aim trainers, simple memory grids — measure how fast you react to something you can still see. Blindspot removes the cue entirely before you answer. You’re not reacting; you’re recalling. That makes it a genuine attention span test and visual memory test in one, rather than a pure reflex check.

Adjustable Difficulty

Three settings control how hard each round gets:

• Total balls — more balls means more visual clutter to filter out
• Red balls — more targets to track and hold in memory at once
• Speed — faster movement makes positions harder to anchor mentally

Complete a round with no wrong taps and no extra chances, and you earn a Perfect bonus. Tap the wrong ball, and you can spend an extra chance to keep going — at a small cost to your final score.

A Leaderboard That Rewards Real Difficulty

Every score you save competes on a live Top 100 leaderboard, ranked by round difficulty first and total score second — so a hard round with fewer raw points can still beat an easy one padded with volume. You can attach a name and Instagram handle, edit your profile anytime, and get real-time toast notifications when other players set new scores or land in the spotlight.

Who This Focus Test Is For

Gamers looking to sharpen visual tracking for fast-paced games, students and remote workers curious about their own attention span, or anyone who’s tried an ADHD-style focus test online out of curiosity — Blindspot works as a quick, repeatable way to see how your concentration holds up once the obvious cues disappear.

FAQs

What is an object tracking test?
An object tracking test measures how well you can watch and remember multiple moving items at once, even after visual cues (like color) are removed. Blindspot is a red-ball version of this task: track the red balls, then identify them from memory once they’ve faded to white.

Is the red ball challenge the same as this game?
Blindspot is inspired by the viral “follow the red ball” challenge seen on social media, but built as a full playable game with adjustable difficulty, scoring, and a global leaderboard — not just a single video clip.

Is Blindspot a real focus or attention test?
It’s designed for entertainment and self-testing purposes, using the same principles as multiple object tracking research used in cognitive and sports vision studies. It isn’t a clinical or diagnostic tool, including for ADHD — if you have concerns about attention or focus, talk to a healthcare professional.

Is Blindspot free to play?
Yes, completely free, with no download or signup required.

How is my score calculated?
Your round score depends on how many red balls you correctly identified, the total number of balls on screen, the speed setting, and whether you finished with zero mistakes (a “Perfect” run adds a bonus).

What happens if I tap the wrong ball?
You can use an extra chance to keep playing, but that disqualifies you from a Perfect run and applies a small penalty to your final score.

How does the leaderboard ranking work?
Entries are sorted by round difficulty score first, then total accumulated score — so harder rounds outrank easier ones with similar results. Each device keeps only its best score.

Do I need an account to appear on the leaderboard?
No account needed — just enter a name (and optionally an Instagram handle) when saving your score, linked automatically to your device.

Can I change my name or Instagram handle later?
Yes, use Edit Profile to update either field — it updates all your existing leaderboard entries at once.
