MAHJONG FISHES

There are mahjong games with birds, animals and even butterflies, and this puzzle with fish! The colorful little fish are native to the warm southern seas, where they frolic around surrounded by coral and dark blue water. However, we will not discuss the species composition of fish in this game, although there are parrots, clowns, and groupers, for us the rules are much more important. And they are the same as in any connect mahjong game. Find two chips with identical fish that are not covered by neighboring ones, between which you can draw a line on a plane with no more than two right angles. It may sound abstruse, but once you start playing, you'll quickly understand the meaning.
