Editing Mario Golf: World Tour

'''''Mario Golf: World Tour''''' has the most courses of all ''[[Mario Golf (series)|Mario Golf]]'' games, with 16, including the downloadable courses, making a total of 234 holes. The Castle Club courses have 18 holes and have championships that the [[Mii]] can compete in against other ''[[Super Mario (franchise)|Super Mario]]'' characters. The Mario World Courses contain gimmicks based on different ''Super Mario'' games and have nine holes. All these courses can be accessed through both Mario Golf (quick round) and Castle Club. The six downloadable courses, which could be bought with real money, are taken from the [[Nintendo 64]] game with updated music and graphics. Some of these courses have changed appearances to look like specific worlds from ''[[New Super Mario Bros. U]]''.  

Castle Club is a story mode where the player's [[Mii]] tackles different tournaments (similar to the story modes from previous handheld ''Mario Golf'' games). The building is the Mushroom Kingdom counterpart to real-life golf country clubs. To the left and right of the entrance are the boys' and girls' locker rooms respectively.  At the center of the lobby are two staircases leading to the basement, where the player can enter regional and world tournaments and ask the purple Toad for advice on golf terminology. To the left of the doorway to the Castle Club's exterior is the boutique, where the player's Mii is able to use [[Coin]]s to buy equipment that will affect its stats, such as drive distance and shot trajectory, similar to the Mii customization feature in ''[[Mario Tennis Open]]''. The player can change his/her gear by accessing the pause menu from anywhere in the Castle Club, or by going to the locker room of the Mii's gender and pressing {{button|3ds|A}} when in front of the locker. Above the boutique is the Royal Room, where most of the ''Super Mario'' playable characters can be met. Located opposite the boutique is the gym, and on top of that is the trophy room. Just outside the Castle Club is the Caddie Master's booth where the player can sign up for a handicap tournament. After completing that, the player will be allowed to compete in tournaments, located on the [[Forest Course]], the [[Seaside Course]], and the [[Mountain Course]] in that order. The entrances to these courses are located to the right of the booth, and when the player goes into one of them, he/she can either go for a stroke play (front tees are used) or the course championship (back tees are used).  Completing either of these modes can raise or lower the player's handicap, and when a tournament is won, the player appears in the Royal Room to receive his/her trophy from [[Princess Peach]].

In addition to Castle Club Tournaments, Nintendo has also created Mario Open tournaments which allow the use of ''Super Mario'' characters, and are played on Mario World courses and downloadable courses. Tournaments in this category cover nine holes, so on the downloadable courses, either the front nine or back nine are played on. All of these tournaments are world tournaments, but they award pieces of clothing for the Mii in the same way as the regional tournaments. Mario Open tournaments are stroke-play or coin-collecting tournaments, and when there are no item restrictions, players start out with three different items. Fixed-character tournaments limit players to using a specific character, and that character is not allowed to have a star rank. In limited-item tournaments, players can only use a particular item, and they start out with five of it. Players can also make their own unofficial Mario Open tournaments under rules of their choice for other players to enjoy.

On April 17th, a demo of the game was released on the Nintendo eShop for Europe, making this strictly the second ''Super Mario'' game (preceded by ''[[Mario & Luigi: Dream Team]]'') to have a publicly released demo for download. The demo was later released in North America on April 24. It uses 873 blocks when downloaded and offers ten uses (fifteen for the North American demo).
