Test your skill with this not-so-easy “4 pics 1 word” style quiz game with a world city theme! We want to make this more challenging for you to guess. We try not to reveal too much about the identity of the city in the four travel photos. You have to work hard with the letters given in each level to solve the puzzle. Use “remove a letter” or “reveal a letter” hints to guide you past the levels if you are stuck.
