Kurotto

Game Rules: Decide every cell: circles stay white. Each numbered circle counts all cells in the black groups touching it by an edge, including bends and branches. Count a group once even if it touches twice; diagonal contact does not count. An empty circle is white without a count. Other white cells are allowed. Tap to shade or erase; hold to mark white with a dot or clear it. Drag paints the starting state. Sizes and counts follow settings and clues; connectivity rules stay the same at every difficulty.
