A Tents puzzle consists of a square or rectangular array of squares in which some of the squares contain a tree, with the remainder containing only grass. The puzzle is solved by placing tents into selected grassy squares so that each tree has its own tent (either horizontally or vertically), and each tent has its own tree (either horizontally or vertically). The squares in which tents are placed must not touch on either the sides or the corners. Numbers located to the side and to the bottom of the puzzle tell you how many tents are in each row and column.

These graphics show a Tents puzzle in the Crossword Express Solve screen and a PNG graphic file produced by the program's print function, showing the complete puzzle solution. See also a  full size version of a PDF file. 

The key features of the Crossword Express Tents Construction function are as follows:-
  • Fully automatic construction of puzzles. Puzzle sizes can range from a minimum of 5x5 up to a maximum of 10x10.

  • A multi-build function allows the construction of many puzzles (thousands if necessary) in a single operation.

  • Puzzles can be printed in an unprecedented range of user controlled colors and formats. Output can be sent direct to the printer or, if you install the appropriate software, it can be sent to a PDF file. The recommended software for this purpose is  Primo PDF which you can download free from their website,  although you might consider sending them a small donation if you find their program useful. Mac users will be able to create a PDF file directly from the screen provided by the printer driver.

  • Formatted output can also be exported from the Print screen to graphic files which conform to the BMP, GIF, JPG or PNG formats.

  • A fully interactive Solve function is available to allow you to solve the puzzles "on screen" without needing to print them.
