Super September

Super September is an event that is taking place in September 2013, spanning from 1 September until 30 September. During the event, members are able to complete daily Super Challenges. These challenges take many forms, but each day there is a unique challenge. None of the challenges have skill or quest requirements. Progress through the day's challenge is shown the in the chatbox in cyan text, and completion is displayed in teal text , and the messages appear when the game messages are filtered, unlike normal daily challenges. These challenges must be completed on the given day and expire the next day.

All experience gained from Daily Challenges is also boosted during the event, with all challenges rewarding 2x the XP they normally would, although Dungeoneering challenges only reward 1.25x of their regular XP.

Behind the Scenes
These challenges were shown or mentioned in the Behind the Scenes:
 * Fill your inventory with 28 different varieties of food.

Hiscores events
During two different weeks during the period of September, one starting at 6 September and one at 20 September, a hiscore event took place. These events last for a week and can be repeated as many times a player wants. When a player ends in the top 1000 of either of the events, additional rewards may be obtained.

Rewards
Every challenge completed awards experience, as well as milestone rewards when handing the challenge in at the Quartermaster in Burthorpe.

Experience
Experience is awarded for handing in challenges to the Quartermaster as follows:

Other Rewards
Milestone rewards are awarded after completing a certain number of challenges, starting at 5. Note that these challenges do not have to be completed in a row. Some of the rewards award Loyalty Points on top of the other items. Note that you do not have to hand the challenge in at the Quartermaster for it to count towards the Milestone rewards. All the rewards are found here:

Hiscores rewards
Additionally, if you finish in the top 1000 of one of the two hiscores events, you will obtain the following two titles (and the Superior hero outfit, if you haven't yet).
 * Super super [Name]
 * Super supervillain [Name]

Trivia

 * The challenge Everybody Dance Now is a reference to the song Gonna Make You Sweat by the C & C Music Factory.
 * The challenge "There's always a bigger fish" is a reference to the movie Star Wars Episode I: The Phantom Menace.
 * You still get the popup message in F2P, but it's different than in P2P.
 * Players with 200m xp in 12 or more skills were originally unable to complete the challenge Mad Skills due to being unable to receive xp in these skills. This was changed quickly so that performing activities which would normally give xp would count for the challenge, even if the skill was maxed.
