Diablos were said to have been invented by the Chinese about 4000 years ago. If you have not seen one, in simple terms, it is a game played by controlling a sort of ‘top’ on a cord strung onto the end of two sticks.
They were all the rage in Europe at the beginning of the last century and are now back and rapidly gaining in popularity.
You can with practice develop endless skills by throwing the ‘top’ in the air catching it and in time perform endless complex tricks.
