Solve a random Easy, Medium, Hard Japanese logic puzzle chosen from today's collection. Note: If the puzzle doesn't look as it should try using 'Compatibility Mode'.
Objective / Rules - A numbered square shows the number of white squares, in total, reachable from that square, going horizontally or vertically until a wall or black square is reached, including the square with the number (i.e. the range). - e.g. a square containing a 4 has itself, and exactly three other connected white squares, in total, horizontally and vertically. - Black squares do not touch horizontally or vertically. - Any white square can be reached from any other (i.e. they are connected).
Mouse Usage Left-click = Blank >> White >> Black >> Blank. Right-click = Blank >> Black >> White >> Blank. Click a number to mark it as dealt with.
Checking If you click 'Check' the system will check for incorrect squares. If 'Show mistakes when checking' is checked they will be marked with a red X.
