Skyscrapers (Battleships) by Palmer Mebane

PDF

Theme: Logical

Author/Opus: This is the 45th puzzle from our contributing puzzlemaster Palmer Mebane.

Rules: Combination of Skyscrapers and Battleships. Place the indicated fleet into the grid so that ships do not touch each other not even diagonally. The size of the ship represents its height as in a Skyscrapers puzzle, and the clues outside the grid indicate how many ships are visible in that direction. Ships block the view of any ship of equal or smaller size behind them.

Answer String: For each row from top to bottom, enter the number of the first column from the left where a ship segment appears (enter just the last digit for any two-digit number). If the row is empty, enter 0. Enter these numbers as a single string with no separators.

Time Standards (highlight to view): Grandmaster = 3:45, Master = 8:00, Expert = 16:00

Theme: Logical

Author/Opus: This is the 43rd puzzle from our contributing puzzlemaster Palmer Mebane.

Rules: Combination of Tetromino/object placement and Spiral Galaxies puzzle styles. Place the seven tetromino shapes into the grid, rotations allowed but not reflections. Tetrominoes do not touch each other not even diagonally and they do not cover any cell with part of a white circle. Digits on the left/top of the grid indicate the number of cells used by tetrominoes in that row/column. Digits on the right/bottom indicate the number of different tetromino shapes partially in that row/column. All remaining white cells must be part of connected regions – “galaxies” – with rotational symmetry. Each galaxy must have exactly one circle at its center of rotational symmetry.

Answer String: For each cell in the marked rows, enter the tetromino shape (as a capital letter IJLOSTZ) or the galaxy size in cells (enter just the last digit for any two-digit number). Separate the rows with a comma. An example answer would be “772TTT44SS,6664333LLL”.

Time Standards (highlight to view): Grandmaster = 4:45, Master = 9:30, Expert = 19:00
