Final Fantasy Brave Exvius Tap!

Final Fantasy Brave Exvius Tap! is a free-to-play role-playing game developed by Super Appli, and published through Facebook by Square Enix for iOS and Android devices. It is a spinoff of the mobile game Final Fantasy Brave Exvius.

World
The world map, is presented as a set of points on the side of a crystal tower. The frame presented never shifts, but the numbering on the points increase to reflect the player's progress.

Battle system
Brave Exvius Tap! 's battle system consists of the player tapping the screen to make Rain swing his sword, while the other party members attack automatically through a speed stat determined by their level and perks provided by equipped weapons. Each level is divided into three battles consisting of two regular enemies and one Boss. Each set of ten levels features one set of recurring enemies before the ninth level of each subset which hosts a unique Boss character. This pattern continues until the party reaches the tower's summit at the 1000th floor. When a party member attacks enough times, their attack bar will appear in a rainbow color, and when their icon is tapped they will deliver a special attack, which can only be upgraded after reaching the 500th floor. Lapis dropped by enemies is used to level characters up, giving them boosted stats and added particle effects for a cosmetic change.

Shop system
After reaching the Tower's 100th level, the player is able to spend their accumulated Gil, dropped by enemies in Battle mode, on weapons from the Moogle shop. The weapons are randomly selected and, at the Bronze tier, will be ranked from one to three stars. If the player receives a weapon they already have, the two will automatically be fused into a higher level iteration of the same weapon.

Raid Battles
In Raid Battles, one can join with other players to take on more difficult battles and receive weapons in return.

Characters

 * Rain – A knight of the Kingdom of Grandshelt. A precocious pilot who was entrusted with command of an airship at the tender age of thirteen, he maintains a carefree—some might say lackadaisical—demeanor. He has the unwavering trust of the king and his nation's people, in large part due to his father's reputation as a stalwart knight of the kingdom.
 * Lasswell – A knight of the Kingdom of Grandshelt, he shares command of an airship with his childhood friend Rain. His skills are on par with Rain's, and his no-nonsense attitude has earned him the trust of his superiors and subordinates alike. However, he has a tendency to get dragged along by Rain against his own better judgment.
 * Fina - A young girl who emerged from an earth crystal with no recollection of her past save for her name. Fina's lack of general knowledge prompts her to act with the innocence and curiosity of a child. She is proficient with white magic and the bow and arrow, though where she acquired such impressive skills, she cannot say.
 * Dark Fina - Fina's alternate form. This, it seems, is the true Fina, before she lost her memories. She possesses powerful magic and a quick tongue—both mainly offensive. Yet behind her jibes and patronizing tone, one clearly senses a firm determination.
 * Lid - An airship engineer from Dirnado, who grew from a kid toying with machines in her parents' workshop to the finest engineer in the Industrial City. Lid is determined to inherit the name Cid, an honor granted only to the greatest in her trade. Her only serious flaw seems to be her love of money.
 * Nichol - A military tactician for the Olderion Federation, and one of the Wardens of the Waters, who have protected the Water Shrine for generations. His dedication to his role means that he disregards his own feelings, always choosing the greatest good for the greatest number. Never one to mince words, he is often misunderstood as a cynic.
 * Jake - The leader of the rebel army opposing the Zoldaad Empire. A lighthearted man by nature, Jake is even more easily swayed by women than Rain. However, he hides a fierce resolution within to protect those who suffer from oppression. When Jake first met Rain and his comrades, he made use of his guile and cunning to manipulate them into doing his bidding. These resourceful qualities, among others, are what make him such an efficient leader.
 * Sakura - A mage Rain and his companions met in Zoldaad. Sakura's childlike appearance hides the fact that she is well over 700 years old, as well as the main leader behind the founding of Mysidia. Her age shows in her dignified manner of speaking, and she has earned the respect of all the mages in the nation for her incredible magical prowess. Curiously, her true identity remains a mystery to those around her.
 * Veritas of the Dark - A mysterious man who laid siege to Grandshelt Castle. Dressed in pitch-black armor, he introduced himself as one of the Sworn Six of Paladia, who seek the destruction of the crystals scattered across the world.

Story
