Puzzle with changeable shapes board and cover

Abstract

The present disclosure provides a puzzle apparatus which is a combination of a main board having shaped indents, a plurality of corresponding puzzle pieces, and a deformable and detachable cover with a grip tab. The puzzle pieces can be held in place against the main board by placing the cover over, regardless of whether they are inserted in the indents or not, due to the length of the cover side walls, allowing for easy storage and transportation without risking the pieces falling out. When a user wishes to use the puzzle the cover can be quickly and ergonomically removed via the grip tab. As the cover piece and main board are provided as a set, any number of puzzle board profiles and puzzle shapes can be achieved.
