Unique puzzles. Lighthouse Battleships - a combination of the "Beacons" and "Sea Battle" puzzles. The game is a square or rectangular grid. Contains "beacons" - cells with numbers, meaning the total number of ship fragments in the same row and in the same column as the beacon. The cell with the number cannot contain a fragment of the ship. Ships cannot touch each other or beacons, even diagonally. The number of ships on the field: 1 ship per 4 cells, 2 ships per 3 cells, 3 ships per 2 cells, 4 ships per cell. On the fields 14x14 and above there is an additional ship for 5 cells. Sometimes some parts of the ship are already open. Yajilin may be called: "Boomerang," "Arrow Ring," "Straight and Arrow." The goal is to arrange the squares in black and draw a closed loop that does not intersect itself and which should not pass through the black cells and arrows. Black cells cannot touch vertically or horizontally. Numbers in the cells indicate the exact number of black cells. If the cell has the number 2 and an arrow pointing to the left, this means that there are 2 black cells in the row to the left of such a cell. When a cell does not contain an arrow and is not black, then it contains a loop segment. Cells with arrows do not count as black cells. There may be black cells on the field, which are not indicated by any of the arrows. Calcudoku - this is a mathematical and logical puzzle. It is necessary to fill the grid with numbers so that in each line and in each column they are not repeated. The number in the corner of each selected block is the result of an arithmetic operation on the digits in this block. The numbers inside the block can be repeated. The puzzle can be called Square Wisdom, Kendoku. Tridoku. The puzzle consists of nine large triangles. Each of them contains nine small triangles. Figures from 1 to 9 should be placed in the cells of each large triangle. The field contains additional lines, the cells of which must also contain non-repeating numbers. Two adjoining triangular cells should not contain the same numbers (even if the cells touch each other with only one point). + 250 sudokus difficult level that can be downloaded and printed. + 250 maze puzzles that can be downloaded and printed. Only 1 verified solution. All answers are at the end of the book. Exclusive puzzles. A link to the surprise is at the end of the book. An excellent book for free time and mind exploration.
