This is an experimental level in development. The crosswords are split into 10 sets that each repeat after 20 days. So once you have had enough of the repetition of one set, click the Set buttons to start the next one. The words are roughly harder for each subsequent set.
Book requests: we strive to improve quality of the word and meaning choices before publishing crossword books. However if you would like to request a book of these crosswords to be published earlier please contact us with the language and level.
