LayerStylePick separates single-contour shapes from nested multi-layer outlines. Each round asks you to tap either SINGLE-layer or MULTI-layer styles. Correct taps score. Wrong style taps earn mistakes, and three mistakes end the game. Count the rings carefully: one outer contour means single, while nested circles mean multi. Early rounds make the difference obvious, but later boards mix similar sizes and closer nested spacing. Read the prompt, inspect depth, and ignore color distractions. Clear every matching style before the next refresh. It is a simple depth-reading drill that still becomes tricky as outlines grow more similar.
