Ripple Effect (Hakyuu)

Game Rules: Ripple Effect

Fill each room with 1 to its size. Two copies of the same digit in a row or column need at least that many cells between them, even across room borders.

Fill each outlined room with 1 through its cell count, once each. Equal digits v in one row or column need at least v cells BETWEEN them, even across room borders. Equal diagonal digits are allowed. Dark digits are fixed clues; blue digits are your entries. Tap to select, then use the number keys; Clear erases. Hold to toggle pencil mode; repeat a candidate key to remove it. Sizes follow settings and room counts (up to 9); difficulty changes clues and deduction depth, never the rules.
