PAPER PRACTICE

Tents & Trees: Clear impossible tent squares

Three fixed studies, followed by separate answer pages. The links and IDs match the online collection.

Put one tent beside each tree, directly above, below, left or right. Each tent belongs to one different tree. Tents cannot touch, even diagonally. The row and column counts give the required number of tents. Mark grass where a tent cannot go.

Two checkpoints in the solution

  1. A row or column clue of zero allows no tents. Mark R1C2, R1C4, R2C2, R2C3, R2C4, R2C5, R2C6, R3C2, R3C4, R4C4, R5C1, R5C2, R5C3, R5C4, R5C5, R6C2, R6C4 as grass; tree squares stay unchanged.
  2. R1C3, R3C3, R4C5, R6C1, R6C3, R6C5 have no tree directly above, below, left or right. A diagonal tree is not sufficient, so these squares are grass.
