A rectangle is an accessory for a level in which possesses a rectangle shape on the level, but not on the square cells.
Description
It makes the level itself have a rectangle shape. If the first number in the board size is superior to the second number, than it is a horizontal rectangle (e.g. 14x11. Since 14 is bigger than 11, then it is a horizontal rectangle). If the second number in the board size is superior to the first number, than it is a vertical rectangle (e.g. 5x6. Since 6 is bigger than 5, then it is a vertical rectangle).
Vertical rectangles in the Flow Free App are much more common than horizontal rectangles. In fact, horizontal rectangles. In fact, out of 5040 levels in the Flow Free App, there are at least 500 levels that are vertical rectangles and less than 100 levels are horizontal rectangles. These include levels that have a rectangle board size, but a different level shape.
A couple levels in Warps Sampler (particularly the first and second levels) are levels that have a horizontal rectangle size and shape, which are 5x3 and 6x3, respectively, even though in the Warps Sampler, the size isn't focused on the board size, but rather on the quantity of warps there are in these levels.
Despite the rectangular shape for the level, the shape of the square cells don't change, logically. Otherwise, the level would have a square board size like 6x6 or 14x14.
Looks
A level with this accessory can either be a vertical rectangle or a horizontal rectangle. A horizontal rectangle is shorter and wider, while a vertical rectangle is taller and less wide.
