More picture frames

Various modifications have been made to place each puzzle on the main stage. One of them is picture frames, which are made in various sizes.

They are usually square in shape, but some require special frames because of the shape of the puzzle. The puzzle below is a typical example.

A square picture frame is made up of four trapezoidal parts: top, bottom, left and right, but the top frame is made up of three parts as shown below.

In addition, we will gradually create picture frames that match the puzzle’s composition.
