Download the puzzles from the September 2020 print issue of Chemistry World

Shortly after we finalised the print version of this month’s Chemistry World, we realised there were spelling errors affecting the solutions to 16 Across (Cryptic crossword) and 14 Across (Quick Crossword). We thought it would be unfair to give our online puzzlers a totally different quiz, so here you can download the September puzzle pages complete with embarrassing mistakes. We’ll try to do better in future, and will accept entries for the puzzle competitions with these answers left blank (or with your best guess).

There are four prize puzzles: cryptic crossword, quick crossword, wordoku and science scramble. For each puzzle, a winner will be selected from all the correct entries received. The winners will receive a £25 UK book voucher, or alternative of equivalent value for non-UK residents. You can enter any or all of the prize draws, but each entrant is only eligible to win one of the individual prizes each month.

This month we can only accept electronic entries for the puzzle competitions. Please send a photograph or scan of your completed puzzles to by 20 September 2020.1
