Garden Fence asks for one closed loop along the grid lines of a dot board. Numbered beds show how many of their four sides must lie on the fence; blank beds give no count. Cross marks are pencil notes only—they do not count as fencing and are not required at the finish.
Tap a segment to cycle through fence, cross, and clear. Drag from dot to dot to lay several fence segments in one stroke, or sweep along a row to fence multiple sides quickly. Every dot that the loop uses must join exactly two fence segments: no dead ends, no branches, and no crossing paths. The loop may not split into two separate rings.
Worked example
Suppose a bed labelled 3 sits in a corner of the garden. It already has two sides on the outer border, so exactly one more of its inward-facing sides must be fenced. If the neighbour to the right is a blank bed, you might still need that shared edge fenced to satisfy the numbered bed, which tells you the corner cell is heavily constrained before you draw the long outer boundary.
Strategy tips
Start from high numbers. A bed marked 4 must be fully enclosed. A bed marked 0 cannot touch the fence at all. Those extremes fix many edges early.
Follow the corner rule. On a rectangular plot, the outer border consumes two sides from each corner bed. Combine that fact with the bed's number to learn whether the loop turns inward along a particular edge.
Use crosses freely. Mark segments you know the loop avoids; Hint will explain one deduction if you are stuck, but crosses are optional notes for your own reasoning.
Keyboard players can Tab to a segment and press Enter or Space to cycle states. The puzzle completes when every numbered bed is satisfied and the fence forms a single closed loop.
