How long is the flash display?

On easy difficulty the object shows for about 1.5 seconds. Harder modes reduce this to under a second.

What pixel error is a top-tier score?

Under 15 px is excellent. Under 30 px is solid. Most first-time players average 40–60 px error.

Does the object type affect difficulty?

Yes — distinctive shapes or colors are easier to "tag" spatially than plain dots. Harder levels use uniform gray circles to remove object identity cues.

Can You Place It Back Exactly?

This is a pure visual memory test — an object flashes at a specific location, then moves away. You drag it back to where it was. Your score is the pixel distance between the object's original position and where you placed it. No landmarks, no grid — just your brain's ability to encode and replay spatial coordinates, which turns out to be surprisingly imprecise beyond 20–30 px of accuracy.

How to Play

An object flashes briefly at a random position on the canvas.
The object moves to a "holding" position after the flash.
Drag the object back to where you think it originally appeared.
Release and see your placement error in pixels.

Why It's Hard

Allocentric memory — remembering where something was relative to the blank canvas — is weaker than object memory. Without landmarks or grid lines, your brain stores only a fuzzy spatial "gist." Eye movements made after the flash can shift your perceived origin by 10–20 px, and the longer the delay, the more the memory decays toward the canvas center.

Tips

1Keep your eyes fixed on the flash location for a beat before the object moves — this strengthens the spatial trace.
2Note the object's position relative to the canvas edges as a rough anchor.
3Place quickly — hesitating past 3 seconds increases drift toward the canvas center.
