Six scientifically-grounded games. Each takes minutes and returns an instant Peak Hours™ indicator — no sign-up, no commitment. Your results carry into the full B⁴ Scan.
Name the ink colour, not the word. Sixty seconds that expose your executive control under conflict.
Hold a moving target in mind and match it two steps back. The purest test of working memory.
Respond to everything — except the rare target. Sustained attention over two and a half minutes.
Go with the emotion, stop against it. The affective go / no-go maps inhibition under feeling.
Wait for green, then hit it. The rawest read there is on processing speed and readiness.
Watch a sequence, type it back. Forward and reverse — the classic measure of verbal working memory.
Pick any game and start. Every game is calibrated to a real cognitive paradigm, timed to the millisecond in your browser.
You get an instant Peak Hours™ indicator with the raw metrics behind it — accuracy, reaction time, span.
Take the full B⁴ Scan or book a call to translate the numbers into a plan with Dr. KAF.
Ten minutes across all four dimensions returns your Peak Hours™ number and your R.E.O.B. stage.
