3 Tips for Crossword Master Puzzle 640
Start from the 7-letter answer
Puzzle 640 runs 20 clues with answers between 1 and 7 letters, the longest being Orbiter. 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.
10 of these clues have more than one known answer
Crossword Master reuses clue text across puzzles with different solutions, and 10 of the 20 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.
Where this puzzle sits
Puzzle 640 holds 20 clues against a game average of 18.6, and is part of the 601–700 block. Puzzle 639 comes before it and puzzle 641 after. Difficulty drifts up slowly across the 2,001 puzzles rather than jumping, so neighbours are a fair guide.
Verified Answers, Not Guesses
How we verify puzzle 640
The 20 clue-and-answer pairs on this page come straight from the puzzle data, not from another answer site. Each answer is checked to match the length its grid slot allows, and clue wording is stored exactly as the game shows it — which is what lets us tell you when the same clue has a different answer in another puzzle.

How to Solve a Crossword Master Puzzle
The order that clears a crossword fastest, whatever the theme.
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.
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.
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.
