Online puzzles on the theme of «Valentine's Day» - Initially, all the elements of the puzzle are located in the so-called «pocket» - the horizontal scroll area, which is designed to temporarily store unused elements so that they do not clutter up the collection field - the main area of the screen located directly under the «pocket» in which the puzzle is collected. The collection field is indicated by a gray frame that corresponds to the size of the puzzle to be assembled. But the elements of the puzzle for convenience can also be moved beyond the boundaries of this frame.
Puzzle elements can be dragged with the mouse while holding the left button. Elements located in the «pocket» can be dragged to the main field for collection and vice versa. In order to combine the two elements you just need to bring them to each other with the right side. If the elements really fit, they will be automatically “glued”. Such elements will not be disconnected when dragging.
