Pro tips

3 Tips for Crossword Master Puzzle 580

01

Start from the 7-letter answer

Puzzle 580 runs 19 clues with answers between 1 and 7 letters, the longest being Mistake. Long entries cross the most squares, so filling one confirms a letter in several shorter answers at once — on a grid this size that usually cascades through half the board.

02

7 of these clues have more than one known answer

Crossword Master reuses clue text across puzzles with different solutions, and 7 of the 19 clues on this board are among them. That is why the crossing letters matter more than the clue: check the length first, then the letters you already have, before committing to an answer you remember from another puzzle.

03

Where this puzzle sits

Puzzle 580 holds 19 clues against a game average of 18.6, and is part of the 501–600 block. Puzzle 579 comes before it and puzzle 581 after. Difficulty drifts up slowly across the 2,001 puzzles rather than jumping, so neighbours are a fair guide.

How to Solve a Crossword Master Puzzle

The order that clears a crossword fastest, whatever the theme.

STEP 01

Start with the fills you are certain of

Short answers with common letter patterns anchor the grid. Every letter one of them places is a free constraint on the crossing clues, which is why the grid opens up far faster from the easy corners than from the clue you are stuck on.

STEP 02

Use the crossings, not the clue

When a clue will not give, stop reading it and look at what crosses it. Two or three confirmed letters usually reduce the answer to one candidate, and that is quicker than re-reading a clue you have already failed to solve.

STEP 03

Let the theme carry the long answers

The long entries usually share a theme, so once one of them falls the others follow the same pattern. Solve a long answer and re-read the other long clues immediately — they are rarely independent.
