Cats and dogs are not friends, but not in our virtual world and in the game Jewel Journey, where everything is possible. Professor Peter and his young assistant Kitty are engaged in historical research. Once, working in the archive, the characters accidentally found a very old shabby card with the points drawn on it. Scientists decided to organize an expedition and go on the signs, drawn on the map. To move faster and not depend on bad roads, they equipped a balloon and quickly flew to the first point. After landing, the travelers found a cave with gems. To collect them, you need to swap the neighboring stones and build them in a row of three or more identical.
