📝 How to play Crossword (rules and tricks)

By Miguel Arechaga

The crossword is one of the oldest pastimes around, and it still works for the same reason: every word you get right gives you free clues for the ones that cross it. Here's how to play and where it's best to start so you don't draw a blank.

What is a Crossword?

It's a grid split into white and black squares. The white squares group into horizontal and vertical words, each tied to a numbered clue or definition. The goal is to fill the entire grid with the correct words.

How to play Crossword step by step

  1. Pick a numbered square and read its across or down clue from the list of definitions.
  2. Type the word letter by letter into the matching squares, respecting its exact length.
  3. Every word shares some letters with the words that cross it, so those letters must match in both.
  4. Keep solving clue by clue, using the letters you've already placed to help with the crossing words.
  5. The crossword is complete once every square is filled and every word is correct.

Strategy: start with what you're most sure of

You don't have to solve the clues in order: always start with the words you're most confident about, usually the shortest ones or ones about a topic you know well. Every letter you place there becomes an extra clue for the words that cross it, so a few solved words often unlock several more in a chain.

Pay special attention to words with uncommon letters (like Q, X or Z): since they have fewer possible combinations, they're usually easier to deduce once you have a letter placed from a crossing word.

Quick tips to avoid getting stuck

The crossword is excellent training for vocabulary and associative memory, and it pairs well with Sudoku if you're looking to switch up your puzzle routine without losing that feeling of closing gaps until you complete the whole board.
