Block Design· Advanced

Goal

Look at the target pattern above and recreate the same pattern on the grid below.

How to Play

  • Tap a cell to cycle through colors (white → red → diagonal).
  • Adjust each cell's color to match the target pattern layout.
  • When finished, press the submit button to check your answer.

Rule 1: Match the Pattern

Every cell's color and direction must exactly match the target pattern.

NG

Rule 2: Complete All Cells

Fill every cell with no gaps — there should be no overlaps or missing parts.

Completed Example

  • Tap a cell to cycle through colors (white → red → diagonal).
  • When all cells match the target, you advance to the next problem.
  • Higher scores for fewer attempts and fewer toggles.

Tip

  • First identify the overall symmetry and diagonal directions before filling in cells.
  • Start with corner and edge cells — the rest becomes easier.
  • Made a mistake? Tap the cell again to cycle through colors.

Block Design is a core subtest of the Wechsler Adult Intelligence Scale (WAIS), measuring nonverbal intelligence and visuospatial construction ability. Analyzing and reconstructing visual patterns trains spatial reasoning, visual-motor coordination, and abstract conceptualization.
