Logic puzzle. Pitch a tent next to every tree so that tents never touch each other, not even diagonally, and each row and column holds exactly the number of tents shown on its edge. Solve as many as you can in 150 seconds.
The grid is dotted with trees. Your job is to place tents, one for every tree. Tap an empty cell to place a tent; tap again to mark it with a dot as 'definitely grass' to help you think; tap once more to clear it. Trees themselves cannot be changed.
Three rules must all hold. First, the number of tents in each row and column must match the clue printed on that row's or column's edge. Second, no two tents may touch, not even at a corner — every tent needs empty space all around it. Third, the tents and trees must pair up one to one: each tent sits directly beside (up, down, left, or right of) its own tree, with no tree left unpaired and no tent borrowing another tree.
A tent turns red if it is touching another tent, and an edge number turns green when that line has exactly the right count, so you can see your progress at a glance.
Finish a grid and a new one appears at once. Solve as many as you can before time runs out.
Start from the edge numbers, not the trees. A row or column whose clue is zero can be filled with grass dots immediately, and that often blocks the only awkward square next to a tree, forcing its tent into the one remaining direction. A clue equal to the number of free cells in that line is just as powerful — every one of them must be a tent.
Whenever a tree has only one empty neighbour left, its tent is forced; place it and then mark all eight cells around that tent as grass, because nothing can sit beside a tent. This 'place then fence off' habit turns one deduction into many and is the engine that drives most of the board.
Think in pairs, not in single tents. Because every tent belongs to exactly one tree, a lone tree in a corner or against a wall has very few options, while a tent that could serve two different trees is usually a trap — placing it there would leave one of those trees with no partner later. Look for trees that can only be served from one cell and lock those first.
Use the no-touching rule as hard information, not just a restriction. Once a tent is down, a whole ring of cells becomes grass, which shrinks the options for neighbouring trees and frequently completes a row's count for you. In the timed mode, chase these forced chains rather than guessing — a single forced tent often cascades across half the grid before you need to think again.
