This weekend, we have "Forsmarts 9th Anniversary Squared Contest" in which all the puzzles are Four Squares. It reminded me of one of the puzzles, "Four Square," which I created for the 11th 24Hr Puzzle Championship in 2010. In the coming contest, all four squares have the same puzzle, but in the following puzzle, all four puzzles are different. Write your comments about this puzzle. Hopefully, this puzzle will be good practice for the weekend test.
Rules of the "Four Square" Puzzle
The four puzzle types in this part: Skyscrapers, Battleships, Tents, and Snake, all rely on clue numbers on the outside of the four puzzle grids. Find the missing clues that are shared between the grids so that all puzzles can be solved, and solve them.
Skyscrapers Rules
Place digits 1-6 into the grid so that each digit appears exactly once in each row and in each column, and the clue numbers are the number of buildings that can be seen from the corresponding direction.
Battleships Rules
Place the given fleet into the grid so that ships do not touch each other, not even diagonally. The clue numbers are the number of ship segments in the corresponding direction. Squares marked with ‘X’ can not contain any part of the ship.
Tents Rules
Locate the tents in the grid. Trees and tents appear in distinct pairs, in horizontally or vertically adjacent squares. Tents do not touch each other, not even diagonally. The clue numbers are the total number of tents in the corresponding direction.
Snake Rules
Find a path of sequentially numbered and edge-connected squares starting from 1, passing through 10 and 24, and ending at 30 (1-12 for the example). The path cannot loop back or touch itself, not even diagonally. The clue numbers are the number of times the snake makes a 90-degree turn in the corresponding direction.
