Strategies to play smarter and score higher

  • Two identical adjacent numbers cannot both stay unshaded.
  • Three identical numbers in a row force the middle to be unshaded.
  • Never shade a cell that would isolate an unshaded region.
  • If shading a cell would trap another unshaded cell, the shaded cell must be wrong.
  • Look for numbers that appear only once in a row or column—they are safe.
  • Use connectivity checks after every few placements.
