Events are temporary occurrences that can happen server-wide or in singular worlds. Some events can occur randomly during gameplay, while others are triggered directly by the developers. While active, an event may offer exclusive items unobtainable elsewhere. Most, if not all events last until a certain time limit is reached.
Annual events occur once every year and are generally held to celebrate holidays, such as the Harvest Festival, which is based on the Mid-Autumn Festival. Annual events run for a week, except for WinterFest, which lasts for two.

@Aimster holds a racing event at KYDERBY each year, a reference to the Kentucky Derby. It is usually hosted by moderators and some non-moderators who run the event for 24 hours. A rare item, the Mint Julep is given out as a prize to the winner of the racing event. The owner of the best race track design is also rewarded a prize. @Aimster chooses the top nine worlds from the forums.
STYX (now a former Moderator) used to hold a Fire Festival, which is a reference to the Philippines fire festival. It was held in the world FIRE, which he later sold as he was no longer a moderator, therefore discontinuing the event. Golden Apples were rewarded to players who won the event. Since the event has been discontinued, Golden Apples can now only be obtained from breaking Golden Treasure Hoards.
The Super-Block Event was the first guild event added to the game, and was meant to be the first in a series of Grow Events. The only instance of this event was held during April 13–16, 2018.
Since the event's mechanisms were considered very unsatisfactory, the developers decided to scrap the Super-Block Event and any plans for subsequent Grow Events. Seasonal Clashes were later introduced as a replacement for the original Grow Events.
