The Cipher's Puzzle Letters

Every week, a letter arrives from The Cipher, a self-described expert in codes, clues, and puzzles with a dry sense of humor and zero patience for sloppy thinking. Inside each letter: four puzzles built from words, numbers, and patterns. Solve them if you can.

Each letter delivers four fresh challenges designed to test a different kind of thinking. Word puzzles. Number puzzles. Logic and pattern puzzles. Sometimes all three at once. The Cipher will be watching, in a manner of speaking.
