Running a campground is harder than it looks when every camper wants their own tree and nobody wants a neighbor. Tents and Trees Puzzle unblocked gives you a grid dotted with trees and asks you to place exactly one tent next to each of them, following a few strict rules.
It comes from Simon Tatham's Portable Puzzle Collection, a well-known set of free logic puzzles, and every grid can be cracked by reasoning alone.
How to play Tents and Trees Puzzle
A tent has to share a side with its tree, sitting directly beside it. A diagonal touch does not count as a pairing. Every tree gets its own tent, so the totals of trees and tents always match, though a tent may happen to border a second tree.
Tents hate company. No two can be adjacent, and that includes corner to corner. The numbers along the bottom and right edges give the precise tent total for every column and row.
Mark squares you have ruled out as grass to keep the board readable. When everything checks out, the grid flashes to show you finished. The Type menu offers 8x8, 10x10 and 15x15 grids in Easy or Tricky versions, with Custom for any other size.

Tips
- Clear out the far squares. Any square with no tree directly next to it can never hold a tent, so turn those to grass right away.
- Handle the zeros. A row or column labeled 0 is all grass, and you can fill it in one drag.
- Ring every new tent with grass. All eight neighbors of a tent are off limits, which often unlocks the next move.
- Spot trees with one free side. If only one square next to a tree is still open, its tent goes there.
- Match spaces to the count. When a row needs two tents and only two separate spots remain, both get tents.
- Use red as a warning. Counts and tents turn red when something breaks a rule, so check them before going further.
Tents and Trees Puzzle questions
Do I ever need to guess?
No. Both Easy and Tricky grids have a single solution you can reach by logic. Tricky ones just need longer chains of deduction.
Can I play on a phone or tablet?
Yes. Tap to place a tent, and press and hold on a blank square, then slide, to paint a run of grass. The grid scales to fit the screen.
Is there undo or a solve button?
Yes. Undo and redo have no limit, Restart sets the grid back to the start, and Solve shows the answer if you want to check your work.
