The First Delivery is accessed by clicking on the stained glass window on the bottom left on the Seventh House menu, after the first column of puzzles is unlocked.
In this series of puzzles, you are given a set of letters and must build three words. The first word is five letters long and is selected freely. For the second word and third words, four letters from the first word will be inserted automatically, and you will only be permitted to choose a limited number of letters.
The sets of letters are:
- B C E H L M N O K U. The last four letters of the first word are inserted as the last letters of the second and third.
- C D G H N O P R U Y. The first four letters of the first word are inserted as the first letters of the second and third.
- E G H I M P R T U W. The last four letters of the first word are inserted as the last letters of the second and third.
A Scrabble Solver can be used to help on these puzzles. Usually, only a few 7 letter words will exist (and the third word is always 7 letters), thus giving a small number of potential candidates for the shared part of the word.
