Type 'easy' or 'hard' to begin the quiz. Easy is a 15-degree grid, hard is a 10-degree grid. Then, name any 50K+ World city in each grid square which fits the category label for each square. Grid will be randomly placed each time the quiz is played.
LETTER: means the city starts with that letter.
NUMBER RANGE: (such as 2-5, 10+) means the city contains that many letters (excluding spaces and special characters).
POPULATION RANGE: (such as 250-500K) means the city has that range for its population.
2+ WORDS means the city name has 2 or more words (words denoted by a space or hyphen).
At the end of the quiz the largest population missed answer will show in each square.
Quiz Takers 
An Indian city starting with SH is misspelled in here, with 11 letters. The quiz doesn’t take the right answer.
do you mean Shivamogga? that’s the offical name and it worked for me.
No, I meant Sheikhpura, which is sometimes called Sheikhupura here.
Sheikhupura is a city in Pakistan, different from Sheikhpura, India.
OK, but then: Sheikhupura, which is 11 letters, should not be accepted as an answer in this quiz about 10-letter cities.
ah, yes will remove it from this one.
