2. To resolve a question or situation with ingenuity: “I was able to puzzle out why my brother resigned his job without informing anybody in the family.”
3. A challenging toy designed to amuse while requiring ingenuity to resolve or to complete: “I pass my leisure time by solving cross-word puzzle published in The Tribune everyday.”
