Ranked Battle

"For serious thrill seekers who've leveled up enough, these special battles put your rep on the line. Do well to improve your rank and even earn in-game rewards—and major bragging rights."

- Splatoon's official website

Ranked Battle is a category of modes in Splatoon. It is accessible by level 10 and higher players. The modes included in this category require a higher level of strategy compared to regular modes, and wins and losses are counted toward players' ranks. Players begin with a 'C-' rating, but are able to improve by winning matches. Ranked Battle was released when a large amount of players reached level 10, on June 1st, 2015.

List of Current Modes

 * Splat Zones - Plays similarly to the King of the Hill mode from other video games. It revolves around a central "zone" or "zones", which players must attempt to cover in ink. Whoever retains the zone for a certain amount of time wins.
 * Tower Control - An Inkling must take control of one tower and ride it towards the enemy base. The first team to get the tower to their enemy's base wins.
 * Rainmaker - Uses the Rainmaker weapon, which fires ink tornadoes like the Inkzooka after being fully charged.

Stage Schedule
Stages will rotate out every four hours along with the stages from Turf War, at 02:00, 06:00, 10:00, 14:00, 18:00, and 22:00 UTC. The change in stages are accompanied by an announcement from the Squid Sisters. This announcement will also boot all players out of the lobby after they finish their current match. The mode will also rotate between Splat Zones, Tower Control, and Rainmaker at the same time.

Rank
Winning in Ranked Battle grants Battle Points based on the player's current rank.

Trivia

 * Originally, rank could go up by 20 points at a time, as opposed to the current maximum of 14 points. This can be seen in an image released before Splatoon was finalized.
