This starter contains a global words list variable already loaded with a long list of common English words, plus a few helper blocks such as last letters of ( ) are ( )? and blocks for converting between words, sentences, and lists. You'll use it to solve a crossword puzzle by filtering the word list.

Build predicate blocks like does ( ) have ( ) letters? (using length of and =) and one that checks whether a given letter of a word is a particular letter (using letter ( ) of ( )). Then combine your predicates with and inside keep to find, for example, all the six-letter words whose first letter is r and whose third letter is d — and use scripts like that, one per word, to solve the puzzle from the lab.

Your work autosaves (and you can use the Save button); earlier versions are available from the Revisions dropdown.
