OuterDecorPick separates plain color shapes from ones edged with outer decoration dots. Each round asks for either decorated or plain targets. Tap the correct type to score. Tap the opposite type and you earn a mistake. Three mistakes end the game. Early rounds keep decorations large and easy to spot, but higher scores shrink the dots until decorated and plain shapes look nearly identical. Inspect the outer rim carefully, ignore fill color alone, and read the prompt every round. Clear matching targets as the board refreshes. Simple rules with rising visual subtlety reward careful observation.
