Tents is a calm logic puzzle: a grid of trees, a number beside every row and column, and one tent to pitch next to each tree. Every puzzle has exactly one solution, and you never need to guess. A few habits will get you through every grid.
The rules
Every tree gets its own tent in a square that shares a side with it. Diagonal squares don’t count.
Each tent belongs to exactly one tree, so there are as many tents as trees.
Tents never touch each other, not even at a corner.
The number beside each row and above each column is how many tents that line holds.
How to play
Tap a square to mark it as grass (no tent here). Tap again for a tent, and once more to clear it.
Hold a square to place or remove a tent straight away, or drag across squares to grass them all.
When a row or column has all its tents, its number turns green. Tap it to fill the rest of the line with grass.
Numbers turn red when a line has too many tents or no room left for them. Touching tents turn red too. Undo takes back any change.
Start with the free grass
Before looking for tents, rule out squares. Every row or column marked 0 is all grass. So is every square that doesn’t share a side with a tree, because a tent must always sit beside its tree.
On most grids this clears a third of the board or more, and the tents start to show themselves.
Find the forced tents
A tree with only one free side must have its tent there.
If a row needs as many tents as it has free squares, every free square is a tent.
Once you place a tent, grass the eight squares around it, since no other tent can touch it.
If a line needs two tents but its free squares sit side by side, they can’t both be tents. Look for which ones are forced.
Think about pairs
Each tent serves one tree. When two trees share their only free squares, they use them up between them, and other trees nearby can’t claim those squares. This pairing logic often settles the last few tents on Normal and Hard boards.
Easy is a 6×6 grid, Normal 8×8 and Hard 10×10. Each puzzle is new and has exactly one solution, and your best time is kept for each difficulty.
