Goal

During the preview, memorize the color and location of each endpoint. When play starts they turn gray — connect each matching-color pair with a non-crossing path and fill every cell to win.

How to Play

  • All endpoint colors are revealed during the preview countdown.
  • After they turn gray, press an endpoint and drag through adjacent cells to draw a path.
  • Connecting to a differently-colored endpoint rolls the path back, permanently reveals both endpoint colors, and costs score.
  • The reveal button briefly re-shows all endpoint colors (limited uses).

Non-crossing + full fill

Crossing an existing path cuts it. Every cell must be covered by some path to win.

Tip

  • Memorize pairs that are near each other first — they are fastest to confirm.
  • Start from corners to leave room for longer center paths.
  • Use reveal sparingly; it costs score.

Remembering paired color-location associations while planning non-crossing paths is a dual task that recruits visuospatial working memory (similar to Corsi Block-Tapping) and executive planning (similar to Tower of London).
