Dream Day Wedding: Bella Italia is another entry in a series of hidden object titles with a wedding theme. The player assumes the role of a wedding planner, flying to Italy to prepare the ceremony and other events for a couple of friends. Most of the time, the objective is to find and click on all the items listed at the left side of the screen, on locations related to the plot and filled with assorted paraphernalia scattered around the scenery. In some instances, the goal is to place objects back to their correct spots on the scene. The hint button shows the position of one of the required items, and extra hints can be collected as three bluebirds found on each location. There's a time limit for each scene on the default difficulty, that can be turned off in the options menu.
The occasional mini-games and adventure sections add some variety to the gameplay. In the adventure portions, the player has to perform a task by collecting and using several objects stored inside inventory slots replacing the list. These tools have to be used as in most point-and-click games, by dragging and dropping them on logical places to solve puzzles. The mini-games take place on a separate screen, with implementations of familiar concepts like a memory game with matching pairs of cards, an overhead maze, a spot-the-differences game with two similar images, a jigsaw puzzle with a shredded photograph and other similar challenges.
