Makaro

Game Rules: Makaro

Fill each room of N cells with 1 to N. A black arrow points to the largest adjacent white digit, and equal digits cannot share a side.

Fill each outlined white room of N cells with 1–N once each. Equal digits cannot touch orthogonally, even across room borders; diagonals are allowed. A black arrow points to the unique largest adjacent white digit. Plain black cells are blocked. Dark digits are fixed; blue digits are yours. Select a white cell and use the keypad; Clear erases. Hold a cell to toggle pencil mode; press a candidate again to remove it. Native rooms have at most nine cells. Sizes and counts follow the current settings and clues. Difficulty changes clues or deduction depth, never these rules.
