Neon Hue Flip is a layer-style classification game. Shapes appear as single-layer or nested multi-layer outlines, and you tap the prompted style to score. Wrong choices count as mistakes, with three mistakes ending the run. New shapes keep refreshing, so you must read nesting depth quickly before committing under pressure. Near-nested outlines can trick rushed taps and burn the error budget. There is no undo after a wrong style pick. Clear outline nesting keeps single and multi-layer forms readable when you stay focused. Simple prompt-and-tap rules with a three-wrong fail. Ideal for visual sorting fans who like layer discrimination and retry-friendly high scores.
