Challenges appear after you clear every song on any difficulty. Challenges are random and appear once you clear multiple songs. Songs are determined by ones you have already cleared. The challenge score is determined by rounding your latest score for that song up to the nearest 10,000. You must pass this score in order to successfully complete the challenge.
When a Challenge Appears
Challenges randomly appear after clearing every song in the game on any difficulty.
You are given 3 tries to beat the challenge.
If you successfully beat the challenge, the rewards are RP, a random C card, and a Headphone.
Failing a Challenge
If you cannot beat the score, it tells you "Mission Failed" in red letters and 'booing' is heard as the background music but still you will recieve your normal song reward.
Failing a challenge 3 times will not grant you challenge rewards, and will only grant normal song rewards. Failing a challenge does not lower your scores or affect your stats, cards, or inventory in any way.
Clearing a Challenge
If you are able to beat your high score, it will say 'Cleared' in a light blue color and cheering is heard as the background music.
Note: The stars you achieve have no influence as to whether or not you complete the challenge, only the scored is put into account.
The RP received ranges from about 3,000 RP to around 8,000 RP. The amount given is based on your cards and score, but roughly randomised.
Hitchhiker 히치하이커 11 (ELEVEN)
In SSM, a rare, random song may appear called Hitchhiker - 11. The chances for it to appear are low, and it only appears after you beat a challenge. It is considered the hardest song in the game.
The RP gained from beating the song is the regular RP rewards. After you beat the song, you cannot unlock the song. You also cannot collect the theme cards for this song.
It is from the song created by the producer Hitchhiker.
똑똑똑 (Tok Tok Tok)
Tok Tok Tok is another hidden song by Super Junior. It is by Super Junior's subgroup Super Junior-T, which is the trot subgroup of Super Junior.
It is currently not available to play.
You are also able to use the Super Junior cards.
(can someone add a screenshot of the song?)
