Codeword Packs

Five tiers. Five hundred ciphers.

A codeword is a crossword with the clues taken away — every letter is a number, and you rebuild the alphabet from word shapes alone. No general knowledge required. All 26 letters appear in every grid, and the packs get harder by giving you fewer starting letters: five, four, three, two, then one.

Requires the 7ThirtyWorld Puzzle Studio app.
