During the preview, memorize which tiles are safe (green) and which are danger (red). When play starts, the tiles turn gray — step only on safe tiles to reach G from S.
Stepped-on safe tiles glow faintly green; bumped danger tiles stay red — they serve as your growing map.
Tip
Visuospatial working memory relies on hippocampal and parietal circuits. Memorizing tile positions while planning a route mirrors Corsi Block-Tapping, a validated assay of spatial working memory.
