Have any of you tried playing thimble? It is believed that it is impossible to win here.

The rules of the "roulette of the late XNUMXth century", as the thimblers themselves call it, seem to be simple and clear. You need to guess which of the three caps (glasses, thimble) the ball is under. The whole trick is to keep the ball under the thimble as long as the thimble and dummy players are in the game. But it is worth entering the game to a random person who believed in his observation, the ball immediately, through manipulations of the thimble, disappears from under the thimble.
Statistically, for a possible fair game with three cups, the probability of winning is 33% per kin, respectively. But, it seems, the dog refutes these statistics.
