DarkerShadePick

DarkerShadePick trains fine grayscale discrimination. Two gray blocks appear with similar shades, and you must tap the darker one to score. Tapping the lighter block or missing the timer counts as a mistake. Three mistakes end the game. Early rounds keep contrast easy to spot, but higher scores shrink the gray difference and tighten the countdown until both blocks look almost identical. Compare tone carefully under the same lighting, ignore outline size alone, and decide before time expires. The challenge becomes a patient shade-reading drill as contrast keeps fading with every successful round.
