Rules[edit]

Tents Example.png Tents Example Solution.png

Place tents into the empty cells in the grid, at most one tent per cell. Tents may not be in adjacent cells, not even diagonally. There must be the same number of tents and trees. The tents and trees must match up in such a way that each tent is orthogonally adjacent to its own tree. (It is permissible for a tree to be adjacent to a tent that matches with another tree.)

(Rule and example from PGP IB)

History of the puzzle[edit]

Invented by Leon Balmaekers (Netherlands) in 1989. First published on Breinbrekers magazine. Original title (according to LMD wiki) "Alle Ballen Verzamelen" means "collect all balls."

Variants[edit]

Campsite Trail[edit]

Hybrid with Simple Loop. Probably first appeared in 2009 Finnish National Finals.[1]

Normal Tents rules apply. Then draw a loop that visits every cell except for those occupied by trees or tents. The loop moves orthogonally between the centre of cells and does not touch or cross itself.
