Paddock Plan
Paddock Plan is an area and perimeter puzzle that plays in the browser on phones, tablets and computers, for one player.

Build a fence along the grid lines that gives the animals exactly the area and perimeter they ask for. Two animals share each field and each asks for a different measure, so one shape has to satisfy both. There are 80 fields, moving from rectangles to L-shapes and other shapes around trees and ponds.
How to play
- Drag along the grid lines to build a fence
- Close the fence back at its first post. The animals check it
- Area counts the squares inside. Perimeter counts fence lengths. Undo removes one
The game shows these steps as you play, the first time.

Controls
- Drag along the grid lines from post to post; close the fence at its first post
- Arrows or WASD move the pen, Space puts it down, Backspace or Z undoes, C clears
Tips
- Twelve squares fit this grid as 3 by 4 with 14 lengths of fence or as 2 by 6 with 16, so choose the sides from the perimeter.
- Cutting a corner square out of a rectangle keeps the perimeter the same but takes one square off the area.
- From field 21 every tree must end up inside the fence and every pond outside it, so start the fence along the water.
How are area and perimeter counted?
The area is the number of whole grass squares inside the closed fence, and the perimeter is the number of fence lengths, one for each side of a square the fence runs along. The game counts both the moment the fence closes at its first post.
Does every field have an answer?
Yes. Each field is made from a real shape that fits the grid with its trees inside and ponds outside, and the requests are that shape's own area and perimeter, so at least one fence always works. Other shapes often work too.
