Sudoku Tents - 200 Easy Puzzles 11x11 (Volume 33) Dart Veider Author

Tents (also known as Tents and Trees) is a logic puzzle. The task is a grid of squares, some of them contain trees. The goal is to place tents in some of the remaining squares, in such a way that the following conditions are met: There are exactly as many tents as trees. The tents and trees can be matched up in such a way that each tent is directly adjacent (horizontally or vertically, but not diagonally) to its own tree. However, a tent may be adjacent to other trees as well as its own. No two tents are adjacent horizontally, vertically or diagonally. The number of tents in each row, and in each column, matches the numbers given round the sides of the grid.
