This was the very last Double XP event of 2021 at the time that the last one concluded in November. In the past few years, there have been less than four events in the year OSRS Gold. For obvious reasons. They're required to be big!
When looking towards the next one it was predicted that we'd find it late in February. It proved to be the case. . Since 2014, there's been a Double or Bonus XP event happening at the moment. In light of how the last couple of events have been and we don't anticipate any changes in the future as Jagex appear to have perfected the process.
Players receive 48 hours of Double XP points to take advantage of for approximately 10 days. There was a rare exception in which the event ran for 21 days. However, the 10 day events tend to attract large numbers of players due to their limited nature.
For those who don't know, RuneScape is a major deal. A darned big deal. At least to those in the MMORPG world. The game is now in its 21st season, it's one of the most popular MMORPGs and probably the best free one. The theme is high fantasy, with an equally strong medieval theme that runs through the game. It's a blend that is extremely well-done; just inquire with J.K. Rowling.
