The Tournament of Towns (International Mathematical Tournament of Towns, Турнир Городов, Международный Математический Турнир Городов) is an international mathematical competition for school students originating in Russia.
Tournament of Towns differs from many other similar competitions by its philosophy relying much more upon ingenuity than the drill.
First, problems are difficult (especially in A Level in the Senior division where they are comparable with those at International Mathematical Olympiad but much more ingenious and less technical).
The Tournament of Towns was almost closed down in its early years of development but in 1984 it gained recognition when it became a sub-committee of the USSR Academy of Sciences.
Students performing outstandingly (higher than Diploma) receive an invitation to the Annual International Mathematical Tournament of Towns Summer Conference where during several days they participate in team research projects consisting of the sequence of related problems.
