Game Instructions

Fill numbers into empty cells so every row and column contains numbers from 1 to N with no repeats.

  • Rows & Columns Only: Numbers must be unique within each row and column.
  • Rows, Columns + Two Diagonals: Follow row/column rules, plus numbers on both main diagonals must also be unique.
  • Click an empty cell to select it, then tap a number button below to fill it. Red ⌫ deletes the current value.
  • Grey cells are fixed clues and cannot be edited. Red highlighted cells indicate duplicates in that row, column or diagonal.
  • When all cells are filled, your answer will be checked automatically. If correct, the timer stops and shows your completion time.
  • The Clear button only erases numbers you entered; fixed clue numbers remain intact.
