Advent Calendar is a Treasure Hunter promotion running from 1 December2025 to 24 December2025. During the promotion, players can claim one free item and an additional Treasure Hunter key each day from the Advent Calendar.
The Advent Calendar interface is opened automatically upon logging in, and it can be re-opened from the "Upgrades & Extras" button of the interface ribbon and from the Present Prize Meter interface in Treasure Hunter.
The Advent Calendar was disabled at the beginning of 1 January2026.
Players can open a new window each day during the event, revealing a present with different rewards inside. If opened on the day the window becomes available, a Treasure Hunter key and a point of progress towards both bonus rewards will also be given. The bonus rewards—the Jolly title for all players and a black yo-yo for members—are unlocked after gathering 15 points of progress. If connected to a world prior to the in-game clock reaching 00:00, a player must exit to lobby or world hop before the next day's window will become available.
It is possible to retroactively open any past days' windows. This doesn't yield the Treasure Hunter keys or bonus reward progress that would have been given had the windows been opened on the days they became available.
Navigating left from the window for 1 December causes the window for '0th December' to be shown, featuring some humorous messaging. Clicking the reward enough times gives a Treasure Hunter key, and then disables the window. If the player is an Ironman Mode account, they won't receive the key, but a piece of coal instead. Players with mutes or bans will also receive coal, up to a total of 10 pieces.
