There was a bank robbery in Warshaw. One of the robbers was deadly wounded, but he could escape and came to one of the parts of Georgia.He wrote a letter before he died, in which he admitted how they had robbed different banks. London police knew about the fact  and they went to Georgia to get the evidence. The like-minded people of the robber also knew about this fact  and  they began to travel to get the letter too. If the policemen find the letter first, they will arrest the robbers. And if the robbers find it first, they will destroy it.

P.S. two groups take part in this game: one-policemen and another  one-robbers. Both of them go through the obstacles, planned by us. The winner is the group, which is faster and more quick-witted.
