Batoru is a logic puzzle version of ' Battleships'. Each of the 48 grids contains 100 squares of water. For each vertical or horizontal 'line' of water, you are given the number of 'boat portions' that will appear in the line. Using additional clues, the aim is to use logical deduction to work out the position of the ten ships & submarines on the grid. The puzzles are all graded for difficulty in this fabulous set of challenges.
