Rules: Place a tent next to each tree. Tents cannot touch other tents, not even
diagonally. Some tents are one cell wide and two cells long - like a domino - while other tents are 1x1. All trees in red-colored cells are attached to tents of one kind, and all trees in white cells to tents of the other kind. Clues outside indicate how many tents must be placed in that row.
