@you_wu My bad, I should have explained better. Basically a word puzzle is how I described it before but the puzzle I described is known as a ‘word search’. The image you attached is known as a ‘crossword puzzle’. This puzzle is a puzzle consisting of a grid of squares and blanks into which words crossing vertically and horizontally are written according to clues. You write the answer in the boxes letter by letter. Both ‘crossword puzzles’ and ‘word searches’ are known as word puzzles.
