What should riddles be like?

It is clear that complex riddles are somewhat different from simple logical questions. You should think through a program of developmental classes with such tasks in advance so that the process goes smoothly and without hitches. The most difficult riddles should be:

  • With a catch.
  • Ambiguous.
  • Those that are worth thinking about the answer to.
  • Complex riddles should be selected according to the child’s age. This will help boys and girls find answers according to their level of knowledge.
