1. Who can take part?
The Reply Code Challenge is an online coding competition open to coders aged 16 years and above on the day of the challenge (9th March 2023), from all over the world. There are two challenges: one for Replyers and one for professionals and students who don’t work for Reply. The challenge environment will be different, but the problem statement will be the same.
2. Can I arrange a mixed team of Replyers and externals for this coding game?
No. There are two challenges and two separate leader boards, so mixed teams are not possible.
3. If I register on the platform, am I registered for the competition?
No. To play on 9 March, you need to join a team, create your own, or join the random queue. By registering on the platform, you’ll get updates on upcoming online challenges.
4. Is there a registration fee?
No, this coding challenge is completely free!
5. When does registration close?
You can register until 8 March, 23:59pm, CET.
6. I’ve registered, but I have no teammates. What can I do?
Once you’ve registered, you can join a team, form one, or ask for the ‘random queue’ to assign you one. If you join the random queue, you’ll receive an email with the name of your team before the challenge.
Alternatively, you can join our Discord Server in order to find participants to play with.

To form your team, log in to the Reply Challenges platform, click the “Team up” button and select “Create new team”. Once you’ve formed a team, you’ll see it when you log in to the platform. You can also choose a team name and invite your friends. Just fill in their email addresses and send the invitation. Remember, Replyers play a challenge reserved for them. Mixed teams are not allowed.

No problem. You have until 8th March at 23.59 to join someone else’s team or ask for the ‘random queue’ team assignment. If you join the random queue, you’ll receive a mail with the name of your team before the challenge.
4. Can I change who’s on my team before the challenge day?
No, but you are free to leave your current team. They won’t receive any notification, so remember to tell them.

2. Something’s wrong with the platform. What should we do?
Try reloading the page, then try clearing your cache and cookies. If you’re still having problems, message the Reply Code Masters on chat or email firstname.lastname@example.org.
1. Can we train for the Reply Code Challenge?
We strongly recommend you practice the training problems before the competition starts. That way, you can better understand the type of challenge you might get and how to submit solutions.
2. Which programming language should I know and use?
You can use any programming language to solve the problem.
3. How do we access the training problems?
Just visit the Reply Challenges platform any time. You can upload as many solutions as you want, as many times as you want. The training problem submission works just like the real challenge, except you’ll play alone and not in a team.
4. How do we submit a solution?
Submit a solution by dragging and dropping it or uploading it from your computer. Each submission should contain at least one output file and at least one source code file. Note, you’ll always have to upload the source file, but it’s not mandatory in sandbox mode.
5. Will I see a score when I submit a solution?
Yes. You’ll see a list of scores for all your submissions.
6. Will there be a leader board in the training area?
No, but you’ll see your submission scores.
7. What if we have a question about the problem statement?
You can message the Reply Code Master via chat.
1. When will you publish the problem?
On 9 March, at 4.30pm CET, we’ll publish the problem statement on the challenge platform. It will include the input files you can download from the challenge platform, where you’ll also submit your team’s solution files.
2. When is the leaderboard updated?
We’ll update the leaderboard regularly to show how teams are performing. We’ll also freeze it 30 minutes before the challenge deadline (but we’ll continue to update scores).
1. Whats the University Students League?
You can win a prize for your university, too. The final score that your team will get during the Code Challenge will be added to the University Leaderboard.
2. Whats the prize?
A cool Reply Arcade Game cabinet for the communal areas in your university or a financial donation to support an educational or research project.
3. How can I participate?
You just need to tell us the name of your university right after creating a team or joining an existing one.
4. What about teams from different universities?
The final score of your team will count for every person on the team: if in your team there will be students from different universities the points will be added to each of those.
5. Im not a student anymore, can I still take part in the Univerisity Students League?
Yes, you can, the University Students League is open to Alumni too. Right after creating your team, insert the name of the university where you studied and make it win.
5. Im a Replyer, can I take part in the Univerisity Students League?
No, you cant, but stay tuned for next communications on TamTamy about how to get the official t-shirt and the hubs where to play in the offices.
1. What programming language and tools can we use?
Just like most coding challenges, you can use your favourites.
2. What are the other computer/technical requirements?
You’ll need your own computer with an internet connection.
3. How do we upload a solution?
Your team submits solutions by uploading a file to the challenge platform.
4. How many solutions can we upload?
Your team can submit as many solutions as you like, any time during the challenge. We encourage you submit solutions as soon as you can, to check if your solution is working.
5. How do you calculate the score?
We’ll calculate your team score by summing up the maximum score of each valid input file; the scoring system awards solutions that best optimise the problem. Reply Code Masters may, at any time, reject a solution and invalidate its score. To settle ties, we’ll take time into account.
6. What should our source code look like?
Your team can use publicly released libraries and tools, but your solution must use original code. To be valid, every submission must include a file containing the source code of the program you developed to generate the output. Each source code file must be a UTF-8 plain text file or an archive of UTF-8 files.
7. Can we use any development and execution environment?
Yes. There are no restrictions on the development environment or programming language you use during the contest. You simply write programs to solve a task and submit the results as a text file to the challenge platform. You’re responsible for compiling and running your code on your own computer(s).
1. Who wins?
At the end of the code game, the Reply Code Masters will review and validate the best scoring submission from top-ranked teams on the leaderboard. The Reply Code Masters’ decisions regarding the rules of the coding competition are final.
2. When will you announce the results of the Reply Code Challenge?
We’ll publish a full list of results and notify all finalists no later than 10 days after the day of the challenge.
3. What are the prizes?
At the end of the challenge, the Reply Code Masters will review and validate the best scoring submission from top-ranked teams on the leaderboard. Each member of the winning team will win a Mac Book Pro™ 16 (Chip M1 Pro - CPU 10-core, GPU 16-core, Neural Engine 16-core - 32GB unified memory and 1TB SSD storage). The second-placed team members each win an Oculus Quest 2™, the team members placed third in the ranking each win Apple Air-pods Pro™. The Reply Code Masters’ judgement is final when enforcing competition rules and awarding prizes. We’ll send the winners details of how to claim their prize.
1. Who are the Reply Code Masters?
Reply Code Masters write the problems and are responsible for enforcing all coding challenge rules. They’ll review submissions from teams and award prizes. They may exclude any participants or teams at any time, for breaching competition rules.
2. What do we do if someone’s cheating or behaving badly?
We want to make training sessions and the challenge fair for everyone. So never stop others from taking part – for instance, by overloading the challenge platform, or sending files containing malware, viruses or other code intended to interrupt, destroy or limit the operation of platform, software, hardware or telecoms equipment. This will result in instant disqualification. If you’ve spotted any cheating or unfair behaviour, email email@example.com
