The games will start on March 15. Each team consists of four members. All team members should stick together and move from station to station as a team, either walking or running.

Additional stations could be added to the game itinerary. The goal of each team is to get as many points as possible in the least amount of time. The stations could be encoded in math problems or given as simple addresses. If the team receives an address, it means that the members are to solve two problems, one simple, and one complex. Simple problem requires search for a particular sign\object or drawing of one. Complex problems require solving a problem with given numbers or figures marked directly on the map. If the station is encoded in a math problem, the team will need to find\draw an object or a series of numbers.

For each station, the team receives a number of points. The stations themselves are represented by a two-digit number. The first digit stands for the number of points the team receives for solving simple problems and the second – for solving complex problems. Complex problems can costs 9 or 10 points each. The judges are free to award a lesser number of points for an incomplete answer.

The participants have two competing options, according to the number of categories. The first category is “Lobachevskiy”. Participation terms are as follows:

- Option length – 8,5 hours;
- No judges present
- The answers go unchecked right till the finish line

The second category is Euclid. Participation terms are as follows:

- Option length – 2,5 hours
- English version of the problems is available on demand
- Judges will be present at every station
- Answer check is possible on demand
- If the answer given is incorrect, the team has a chance to give the right one (minus two points for the team the first, minus five the next, if the number of points received for the problem allows it)

Registration address – 180, Sovetskaya St, (Mathematical Park)

**Registration time**

Lobachevskiy category starts at 9 o’clock

Euclid category- at 2:30 p.m.

At the registration address, the teams will get necessary memorabilia and their itinerary. No more than 20 minutes prior to the start, they will get the assigned maps with marked stations and problems. In the remaining few minutes the teams are free to explore solving and travelling options.

**The games start simultaneously for all teams.**

Lobachevskiy category starts at 10 o’clock

Euclid category- at 3:30 p.m.

**Starting point** - 180, Sovetskaya St, (Mathematical Park)

The teams get all the addresses for simple stations and a list of assignments for all stations at the starting point.

**Finish line** - 180, Sovetskaya St, (Mathematical Park)

If a team is late for the finish line for more than 10 minutes, their results will be annulled. If the team is late for less than 10 minutes, the team will lose equal number of points.
