Split Second
Catch both numbers in the blur
Letters flash at the center of the screen about ten times a second, and two numbers hide somewhere in the stream. When it stops, report both. The first one is easy. The second one has a habit of not existing.
That vanishing act is the attentional blink. For a quarter of a second after your brain grabs the first number, it literally cannot grab another, and this game lets you feel that gap from the inside. Catch both and the next stream comes back faster. Miss either and it costs a life.
