Tag is a kind of mosaic puzzle. As in any other puzzle game, you need to assemble an image from individual pieces. The peculiarity of the tag is that all the fragments are tightly bound to each other, and to move, you need to use an empty cell. By moving a fragment to an empty space, you free up another cell, on which the next fragment can already stand. Tag is an insidious puzzle, the further you go, the harder it is to collect it, and the last piece is the most difficult.
