Challenge

Challenge mode is an event mode which was added in Sizzle Season 2023. Officially a replacement for League Battle, Challenges are limited-time competitions of standard modes with unique in-match conditions. They can be played solo or with a team, and feature a two-hour ranked play window similar to League Battle, but unlike League Battle's constant rotations, the windows only occur at a few specific times during a season. Winning five games in a Challenge awards the player with a Shell-Out Token.

Description
Challenges are limited-time competitions of standard modes with unique in-match conditions. They can be played solo or with a team, and feature a two-hour ranked play window similar to League Battle, but unlike League Battle's constant rotations, the windows only occur at a few specific times during a season. The monthly event battles that appeared in League Battle mode were confirmed to return as Challenges. Winning 5 games in a Challenge awards the player with a Shell-Out Token. Just like Anarchy Battles, Challenges unlock when a player reaches Level 10.

List of Challenges
As of Version, there are 14 known challenge modes. The frequency at which challenges occur is random, aside from the Monthly Challenge occurring once per month, and the New Season Challenge occurring at the start of each season.

Rankings
All three timeframes per Challenge feature a list of the Top 100 Teams, Duos and Solo players respectively.

List of rankings:
 * Challenge/Top 100 (Sizzle Season 2023)
 * Challenge/Top 100 (Drizzle Season 2023)

Social media announcements
After a special Challenge has concluded, social media channels of three regions will generally announce the teams that placed first, second, and third with the highest Challenge Power for a certain timeslot. They will also announce the team with the middle ranking among all teams as the Average Roe award. The announcement is accompanied by in-game screenshots of the teams posing on the stages that were available for the Challenge.

The special Challenges that have gotten these announcements are New Season Challenge and Monthly Challenge. To be eligible for announcements on social media, participants have to join and play as a group of 3 to 4 players where half or more have set their Splatfest region to one that matches one of the social media channels.

Challenge Rush


A "Challenge Rush" is a rerun of past Challenges with largely the same stages and modes scheduled for three consecutive days. These reruns are solely announced as such on Japanese social media and while they are meant to be a way for players who missed these past Challenges to still experience them, anyone can participate in them.
 * The "Summer Holidays Challenge Rush" was a rerun of Too Many Trizookas!, The Sheldon Sampler Challenge, and Foggy Notion from 2023-08-01 through 2023-08-03.
 * The second edition of the "Summer Holidays Challenge Rush" was a rerun of Duel of Dynamic Duos, Art Battle for the Ages, and Extreme Jump Battle from 2023-08-22 through 2023-08-24.
 * The "Winter Holidays Challenge Rush" will be a rerun of Too Many Trizookas!, Swim It to Win It, and Sheldon's Dress-Up Showdown from 2023-12-27 through 2023-12-29.
