A wedding planner receives a commission from a couple that wishes to be married in Las Vegas. Every little detail must be worked out before the ceremony, as the groom, the bride and her mother stay on the Palladium Resort hotel.
Dream Day Wedding: Viva Las Vegas is another installment of the hidden object series with a wedding theme. The player assumes the role of the wedding planner, and most of the time the objective is to find and click on all the items from a list at the left side of the screen within a time limit, on various locations around the resort. The time restraints can be turned off at any point in the game at the options screen. In some instances, there's an adventure section where the list becomes an inventory, and objects have to be collected from the scenery to be used later. The stored objects can be combined, dragged and dropped on parts of the screen to solve puzzles. For example, a key can be used on a cupboard to open its doors. Sometimes, a bad situation comes up where the player has only a few minutes to collect all the objects in order to avert some wedding crisis.
Some locations have mini-games that take place inside a window, and are common variations found on many titles: a game with two similar images, where the player has to click on the differences; a matching game where pairs of identical jewelry have to be found, and other challenges of the same type. The casino has some more original titles, like the card game "Tally 21", where the goal is to draw cards from a deck and arrange them in columns totaling 21 points. In the "Perfect Match Plus" game, a series of round chips revolve in circles around the screen, and the player has to flip them to find pairs of matching pictures.
Occasionally, one of the characters makes a call to the cell phone, that starts to ring somewhere on the screen. Taking the call can help or hinder progress, by removing or adding new items to the list. Besides the list objects, most screens have golden dices and coupons scattered around the scenery. The dices give extra hints, that show the exact position of one of the required items. The coupons give extra cash that can be spent on decorations for the reception site.
