01Understanding the Rules

  • Hitori puzzles are played on a square grid containing numbers.
  • Each number represents a different cell on the grid.
  • The goal is to eliminate some numbers based on certain rules.
  • Every row and column must contain unique numbers, and no adjacent cells with a number can be black.
  • Black cells cannot be adjacent horizontally or vertically, and they cannot form a 2x2 square.
  • The remaining numbers must form a connected group, either horizontally or vertically.

02Step-by-Step Solution

  • Start by identifying any duplicate numbers in the rows and columns.
  • Mark these duplicate numbers with an X, indicating that they need to be eliminated.
  • Look for any numbers that are the only option in their respective row or column.
  • These numbers can be circled, indicating that they should remain in the grid.
  • Next, focus on the black cells.
  • Identify any black cells that are adjacent to a circled number, as they can be eliminated.
  • Continue this process of elimination and marking until no more numbers or black cells can be identified.
  • Finally, ensure that the remaining circled numbers are in a connected group, either horizontally or vertically.
  • If all the rules are satisfied and no errors are present, the Hitori puzzle is solved.

03Tips and Strategies

  • Start by scanning the grid for any obvious numbers to be eliminated or circled.
  • Look for rows or columns with only one empty cell, as it can help in identifying the numbers to be circled.
  • Pay attention to the black cells, as they can limit the options for adjacent numbers.
  • Use the process of elimination and deduction to make educated guesses and progress through the puzzle.
  • Practice regularly to improve your solving skills and speed.
