Octopuses are amazing creatures that live in the depths of the sea. They can be very small and harmless, but they are huge in size, called octopuses and pose a danger even to humans. In science fiction stories, giant tentacles grind entire ships. Remember the terrible Kraken - this is also an octopus, but terrifying even for seasoned sailors. The creature in the game Octopus is almost harmless, except that it occupies all the free space, hiding a beautiful picture. Your task is to remove a pair of identical tiles to clear the field.
