DotDensityPick asks you to judge how tightly a shape is filled with dots. Each round mixes sparse and dense dot patterns inside circular targets, and the prompt tells you which density to tap. Correct choices score. Wrong density taps earn mistakes, and three mistakes end the game. Early rounds leave spacing differences obvious, but higher scores shrink the gap between sparse and dense fields until both look nearly alike. Focus on dot spacing rather than shape color, read the prompt carefully, and clear every matching target before the board refreshes. It is a focused visual filter drill that gets harder as contrast fades and distractors multiply.
