Variation: Tetris Battleships (by Jaime Poniachik)


A fleet of five ships is hiding in the grid below. The shapes of the ships are shown to the right of the grid. The numbers beside the grid indicate the number of boxes occupied by ships in each row, while the numbers below the grid indicate the number of occupied boxes in each column. Ships may touch the edge of the board, but cannot touch each other, not even at the corners; however, they may be rotated and reflected with respect to the position shown. Can you find the fleet?
