FIELD: toys.

SUBSTANCE: invention relates to puzzles and can be used in games when conducting competitions or quizzes. In the first version, the puzzle consists of at least five differently shaped rings. In assembled state the rings form a single ring, at what the constituent rings are meshed to form a decorative pattern, and in disassembled state the puzzle makes a permanent connection in the form of ring chain. In the second version, the puzzle consists of five differently shaped rings. In assembled state the rings form a single ring, at what the constituent rings are meshed to form a decorative pattern, and in disassembled state the puzzle makes a permanent connection, at that the first ring from outside is coupled with the second and third ones, the second ring is coupled with the fifth one, the fifth ring is coupled with the fourth one. This structure in disassembled state makes up a five-ring simple chain. In the third version, the puzzle consists of five differently shaped rings. In assembled state the rings form a single ring, at what the constituent rings are meshed to form a decorative pattern, and in disassembled state the puzzle makes a permanent connection, at that, the first ring from outside is coupled with the second, third and fifth ones, the second ring is additionally coupled with the fourth one, which is, in turn, coupled with the fifth ring, which, in its turn, is coupled with the third one. The decorative pattern is symmetrical relative to its centre. In the fourth version, the puzzle consists of at least five differently shaped rings. In assembled state the rings form a single ring, at what the constituent rings are meshed to form a decorative pattern, and in disassembled state the puzzle makes a permanent connection, in which each of the rings is coupled with four other rings. In the fifth version, the puzzle consists of at least five differently shaped rings. In assembled state the rings form a single ring, at what the constituent rings are meshed to form a decorative pattern, and in disassembled state the puzzle makes a permanent connection, in which each of the rings is coupled with four other rings, excluding the first and the last ones, which are coupled with all the other rings, but not to each other.

EFFECT: puzzle is characterised by increased difficulty of assembling.
