- Event Date: 14th - 16th March 2022
- Mode - Online
- M-Decoder is an individual event.
- Participants must log in to the portal between 9:00 PM and 11:00 PM each day to compete.
- M-Decoder is an online event spanning three days which will be open for 2 hours each day from 9:00 PM to 11:00 PM.
- Participants can start the contest any time within this time frame and will be allowed to play for 100 minutes from the start time until the portal has been closed.
- The event will have three sections (Hard, Medium, and Easy).
- The participant will be directed to the Hard section at first, and the other sections remain locked.
- If the participant feels the need to shift to the next section (Medium), the Hard section can be locked, and they can move on to the Medium section.
- The same procedure applies to the transition from the Medium to Easy section.
- The participant with the most points at the end of the third day wins.
- Only one chance will be given to the participant on any particular day to go back from Easy to Medium or Medium to Hard, and this can be used only on one of the three days.
- If you missed out on a day of participation, you can still solve the previous day's problems in the 2 hour period the next day.
- As you may expect, the scores will be reduced for those problems.
- For further details about scoring, please visit the judging criteria.
- You can only see questions from the immediate previous day, i.e, you cannot see the 1st day's questions on the 3rd day.
- Maximum points:
- Hard – 1000
- Medium – 600
- Easy - 300
- Maximum points:
- Hard – 500
- Medium – 300
- Easy - 150
- When you solve a question on your first attempt, you will receive maximum points, and when you solve the same question after moving up from an easier level, you will receive minimum points.
- Scorecurr = Scoremax - (Scoremax * time)/(Scoremax + time)
- Scorecurr = Current Score
- Scoremax = Maximum Score
- Time is measured in seconds.
1) What are the weights assigned to each section per question?
Hard - 1000 points, Medium - 600 points, Easy - 300 points
2) What if many people copy my answer?
For each section, the scoring starts with maximum points and reduces as time progresses. The formula is given in the Judging Criteria below. The minimum number of points a person can score is capped at (Max points for the section) / 2, that is, Hard – 500 points, Medium - 300 points, Easy - 150 points
3) Can I come back to the Hard section after I finish Easy?
You can move one level up, on any one of the three days.
4) What happens if I finish before time?
Your score is locked, and you can’t proceed to earlier sections.
5) Will spare time be carried over to succeeding days?
No, spare time will not be carried over to the succeeding days.

The participants will have to navigate their way through a series of cryptic levels of increasing difficulty, testing various skills to gain points.
At each level, clues will be hidden in the webpage itself. All you need to do is find the clues and the answer that relates all the clues and enter it in the input box provided.
- Participants will be ranked based on the points they score, and the scores will be displayed on the leaderboard.
- In the case of ties, the participant who has completed the most recent level will be given priority.
- In the case of further ties, the player who cracks the latest level first will be ranked first (the timestamps will be in milliseconds to reduce the chances of any ties).
- All the answers should be entered in lowercase without punctuation or spaces. E.g., “Usain Bolt – 9.58” should be typed as “usainbolt958”.
- All decisions by the event managers are final and binding.
