Codebreaker — 100 Codeword Puzzles | Puzzle Studio Pack

⚠️ Requires 7ThirtyWorld Puzzle Studio (sold separately). This is an expansion pack — a puzzle file that loads into the Studio app. It is not a standalone game and will not open on its own.

100 codewords. One starting letter. Nothing else.

The hardest codewords in the collection. A single letter is filled in, and everything after that is deduction: which number is almost certainly E, which short entries can only be a handful of words, which pattern forces a vowel. This is the tier that codeword regulars are actually looking for.

What you get

• 100 puzzles on 13×13 grids, with just one starting letter each
• All 26 letters appear in every single grid — verified individually. With this little given, the alphabet checklist stops being a convenience and becomes your main instrument.
• Every entry is a real, common English word. No abbreviations, no proper nouns, no obscure padding. A one-letter start is only fair if the vocabulary is honest, so it is.
• No word repeats inside a puzzle, and all 100 grids are different
• Its own vocabulary — every word of four letters or more is unique to Codeword, never shared with the crossword or word search packs

If you have never played a codeword before, start with First Cipher instead.
