The game

Is it possible for participants to communicate with the organizers? If so how and in what languages?

What are the parts of the competition and how do they differ?
The competition has two parallel parts. The major part starts at the beginning of the competition and one hour later the Hurry-up series will begin. These will then run in parallel until the competition ends. In the second half of the competition you will be able to skip problems. For the Hurry-up series see the rules and the questions and answers below.

Tasks

When and how will we get new problems to solve during the competition?
You will get the seven initial problems when the competition starts. You can expect new problems with the Hurry-up series. During the competition you must solve the problems you have to get new ones or, in the second part, by skipping problems. The exchange is always one for one. You can find more information in the rules.
How does the difficulty of the problem change with its number?
The average difficulty rises as you do the problems but there still might be some easier problems later on. Also, remember that difficulty is highly individual.
Will we get author's solutions?
Yes, after the end of the competition the solutions will appear on our website. Some time after the end the organizers will still be on the website and will be reacting to your recommendations, experiences or troubles relating the competition or the problems.

Submits

How many significant digits should one give in the solution?
Each task has specified how many significant digits the result should have.
We want to submit the answer to the problem but we can't. What is going on?
The reason must be that you submitted a wrong solution to a task less than a minute ago. If it isn't so then please contact the organizers.
If I submit the wrong answer can I correct it?
Yes, you can answer any question as many times as you want to. Remember though that by submitting wrong answers you will lower the potential point gain from the question and also that you can't answer the problems from the same category incorrectly more than once in a minute (the problems from the main category and the three hurry-up categories). For more information see the rules of the competition.
If we want to submit the solution as a decimal should we use a decimal point or comma?
The symbol is irrelevant but don't use anything to denote thousands (i. e., use 1000000 instead of 1,000,000) .
What are the accepted formats of numbers?

We accept the formats described on following website.

We enable the usage of both the comma and the decimal point.

Scoring

How do we get bonus points?
You can get bonus points for solving a whole collection of Hurry-up problems in the time limit. More about this in the rules.
We got Y points for a problem that was supposed to be worth X points. What happened?
This is caused by the fact that wrong solutions decrease the point gain from that problem. To get more information about this look at the rules.
We solved the problem but this hasn't appeared on the scoreboard yet. How come?
The scoreboard refreshes every two minutes so wait a bit longer. Also remember that twenty minutes before the end of the competition the scoreboard stops refreshing completely to add extra tension.

Hurry up

What is Hurry-up?
It is a period in the competition between 18:00 and 20:00 CET when you can solve new and relatively easy problems. However, you can get bonus points only until 18:30 CET. It is a series of problems that runs in parallel to the major competition. The Hurry-up series has some specific rules though. You can find more about this in the rule section.
How will I find out that the Hurry-up series has begun?
Using a clock. It will also be announced on the noticeboard. You should also have new problems to solve — but to see that refreshing the page will be necessary.

You can get bonus points only in a period between 18:00 and 18:30 CET, after that we will be accepting solutions to the Hurry-up problems but you will not get the bonus points.
