The '''15 Puzzle''' (also known as '''15 Block'''<ref>Nintendo Power, 2004. ''Official Nintendo Final Fantasy I & II: Dawn of Souls Player's Guide'', pg 151.</ref>) is an optional hidden [[minigame]] present in nearly every version of ''[[Final Fantasy]]'', starting from the original [[Nintendo Entertainment System]] release. It is an adaptation of the real-life {{wp|15 puzzle}}, where the player must slide 15 numbered tiles into their correct positions. 

The 15 Puzzle is one of the earliest examples of a minigame in an RPG. Programmer [[Nasir Gebelli]] came up with the minigame on his own, and coded it without a prior request from other members of the development team.<ref>[https://dengekionline.com/soft/recommend/ff-gba/index.html Interview: ''Final Fantasy I & II Advance'']. ''Dengeki'' (in Japanese). 2004. Retrieved July 10, 2022.</ref>

==Gameplay==
The 15 Puzzle can be accessed when the [[Warriors of Light]] are in the [[ship]]. The player must hold down the confirm button while pressing the cancel button a certain number of times. In smartphone releases, the player must instead hold the touch screen with one finger while tapping it with another.

|}

The minigame is not present in the [[MSX2]] version or early mobile phone versions.

The tiles start in a random position each time the minigame begins. From the [[WonderSwan Color]] version onward, the tiles in the correct positions are colored red, while the tiles that are not yet correct are colored light blue. Depending on the version, different rewards may be earned by completing the puzzle.

==Screen layout==
Dialog boxes associated with the minigame were first added in the WonderSwan Color version. The top-right box is the count-up timer, and the bottom box lists the controls. Starting with the [[PlayStation Portable]] version, the lower box was moved to the right and made larger.

The count-up timer displays the number of minutes and seconds elapsed in the format "00:00.00". In the Japanese versions of the game, as well as the English version of ''[[Final Fantasy Origins]]'', the count-up timer uses the format "00m00s00".

In the WonderSwan Color version, the controls are given in plain text. From ''Final Fantasy Origins'' onward, icons are used to indicate the buttons, however the directional pad does not have an associated icon until ''[[Final Fantasy I & II: Dawn of Souls]]''. From the WonderSwan Color version onward, the player has the option to view a list of their current top three times.

In the ''[[Final Fantasy Pixel Remaster|Pixel Remaster]]'' version, the timer and dialog boxes are no longer present, displaying only the confirm and back buttons at the bottom-right corner of the screen.

==Rewards==
In the original NES release, the reward for completing the challenge is 100 [[gil]].

Starting with the WonderSwan Color version, the 15 Puzzle has a count-up timer, and item prizes can be earned depending on the time taken to complete the puzzle. Beginning with ''Final Fantasy I & II: Dawn of Souls'', the list of possible prizes is expanded. Completing the puzzle awards a completion prize, with an additional prize received upon making a new top-three record.

In the ''Pixel Remaster'' version, completing the puzzle no longer offers any reward, but there is an [[achievement]] unlocked by playing it.

==Other appearances==
===Flash game===
[[File:15 Puzzle flash gameplay.png|thumb|250px|Gameplay of the Flash version]]
The defunct Japanese website for ''Final Fantasy I & II: Dawn of Souls'' had a Flash game adaptation of the 15 Puzzle. The Flash game's presentation was based on its appearance in the ''Final Fantasy'' remakes since the WonderSwan Color version, featuring a count-up timer and tiles that changed from blue to red as they were placed in the proper positions. The game had a slider to adjust the game's volume and a button to reset the puzzle.

There were two versions of the Flash game. In one version, players competed to solve the puzzle as quickly as possible, and high scores were compiled on the official site. In the other version, completing the puzzle linked to three wallpapers, each offered in either 800x600 or 1024x768.<ref>[http://web.archive.org/web/20040701104633/http://www.square-enix.co.jp/games/gba/ff1-2/game/15puzzle.swf 15puzzle.swf].

===''Final Fantasy XIV''===
In ''[[Final Fantasy XIV]]'', a version of the minigame called '''Slide I+XIV''' is available to play through the [[Toy Chest]] to players who participated in the [[The Rising|Rising]] event in 2014, in celebration of the first anniversary of ''A Realm Reborn''. In reference to the original incarnation of the puzzle, the background is inspired by the bridge crossing scene from the original ''Final Fantasy''. In addition to a count-up timer, there is also a box that tracks the number of moves taken. There is no reward for completing this version of the minigame.

On December 18, the anniversary of the release of ''Final Fantasy'', the puzzle uses graphics based on its appearance in the NES version of the original game.
