01Understanding the Rules

  • The objective of a Light Up puzzle is to place light bulbs in the grid in such a way that all cells are illuminated.
  • The grid consists of black and white cells. The white cells must be illuminated, while the black cells cannot have light bulbs placed in them.
  • Each white cell contains a number indicating how many bulbs must be placed in its adjacent cells, including diagonally adjacent cells.
  • Bulbs placed in the same row or column must have an unobstructed path to one another. This means that there should be no black cells or other bulbs between them.
  • A bulb illuminates all cells in its row and column, including itself.
  • Cells with a circle in them are called 'clues' and must have a bulb placed in them.

02Starting Strategies

  • Begin by identifying the clues in the grid. These are the cells with circles in them. Place a bulb in each clue cell.
  • Look for cells with high clue numbers. These cells provide important information about the placement of bulbs in their adjacent cells.
  • Identify cells that are already in a solved state. These are cells that can only have one possible configuration based on neighboring clues and existing bulbs.
  • Remember to eliminate impossible bulb placements. If a cell's clue number is less than the remaining empty cells around it, then there cannot be enough bulbs to satisfy the clue. Remove any bulbs that would lead to a contradiction.
  • Use the process of elimination. Trial and error may be necessary, but always consider the logical consequences of your actions to avoid contradictions.

03Advanced Techniques

  • Keep track of possible bulb positions for each cell. This can help you eliminate certain configurations and narrow down the possibilities.
  • Look for hidden relationships between clues. Clues in different rows or columns can affect each other's bulb placements, creating additional constraints.
  • Consider the overall balance of bulbs. Avoid placing too many bulbs in one section of the grid, as this can lead to conflicts later on.
  • Cross-reference clues. If a clue's number is already satisfied by existing bulbs, it can help determine the placement of bulbs in other nearby cells.
  • Use different colors or symbols to represent possible bulb positions. This can aid in visualizing multiple configurations and making comparisons.
