Nanbaboru 5x5 #1 Hard free puzzles to solve online Number Ball
Nanbaboru (distorted by the Japanese pronunciation of the English name "Number Ball") - a logical puzzle of a square shape, invented by Naoki Inaba (Japan). It is necessary to arrange numbers from a given range in some cells of the grid so that in each row and in each column each number is used only once. If there is a circle in the cell, such a cell must contain a number. If there is a cross in a cell, you cannot put a number in this cell.
Place the numbers indicated at the top of the game, in the squares on the board so that each number appears exactly once in each row and column. In the boxes with a circle it is mandatory to enter a value and in the boxes with an "X" no value can be placed.
