There are three main types of crosswords: mini, classic, and cryptic. A "mini" is usually made up of 5 rows and 5 columns, or 6 rows and 6 columns. They are easy to solve because the clues are clear. What you see in newspapers is a classic grid. Most of the time, it's in a 1212, 1313, or 1515 format. The grid for the Indian Express Crossword is 13 by 13. The size depends on the publisher, and as the week goes on, the clues may get harder.
