Tents· Advanced

Goal

Place one tent next to each tree

How to Play

  • Tap an empty cell to place a tent
  • Tap again to mark X (no tent here)
  • Tap once more to clear the cell

Core Rule: Tree-Tent Pairing

Each tent must be orthogonally adjacent (up/down/left/right) to its paired tree. It cannot be placed far away.

OK
NG

Core Rule: No Adjacent Tents

Tents cannot touch each other, not even diagonally. There must be at least one cell gap between them.

OK
NG

Completed Example

  • Each tree must be orthogonally adjacent to exactly one tent
  • Tents cannot touch each other, not even diagonally
  • Numbers on the sides show how many tents are in that row or column
  • Mark empty cells with X to help with elimination

Tip

  • If a row or column clue is 0, mark all empty cells with X
  • If a tree has only one free adjacent cell, the tent position is certain
  • If a row/column already has enough tents, mark the rest with X

Tents puzzles strengthen constraint satisfaction problem (CSP) solving abilities. They require spatial reasoning and elimination simultaneously, contributing to prefrontal cortex activation and working memory improvement.
