Expert Tents
Expert Tents puzzles are 12×12, the largest Tents here, and need a contradiction: assume a tent or grass in a cell, follow the rules a few steps, and when one breaks, the cell is the other.
Expert puzzles need at least one of these techniques, and may use any easier one:
- Contradiction
- Assume the opposite in the marked cell and a rule breaks a few steps later. So it can only be this.
How to play
Tents is a logic puzzle on a square grid of trees. Place exactly one tent beside each tree, directly above, below, left or right of it, so that no two tents touch, not even at a corner, and every row and column holds the number of tents shown at its edge.
Grids grow from 6×6 at Easy to 8×8, 10×10 and 12×12 at Expert. Every puzzle here has exactly one solution that logic alone reaches, and its level is set by the hardest technique it needs.
- Every tree has its own tent directly beside it, never diagonally; there are as many tents as trees.
- Tents never touch each other, not even diagonally.
- The number left of each row and above each column tells how many tents it holds.
- Trees cannot be moved or covered.
Playing on this site
- Tap a cell to place a tent, tap again to mark it as grass, and once more to clear it.
- Drag across cells to paint the same mark along the way; the whole drag is one undo step.
- With a keyboard, use the arrow keys to move and Space to cycle the mark.
- A row or column count fades once its tents are all placed and turns red if it has too many.
- Grass is only a helper: the puzzle is solved as soon as every tent is in place.
- Hint points out misplaced tents and grass first, then names the next technique and highlights where it applies.
- Your puzzle is saved in this browser, so you can come back to it later.
