Puzzle Generator: How to Create Custom Crosswords, Anagrams, and Logic Puzzles

A puzzle generator is the part of a puzzle program that builds a new puzzle from your own material — a word list, a dictionary, or a set of clues — instead of solving one that already exists. Cross+A is a concrete example: it is described as an app for solving and creating puzzles, covering crosswords, anagrams, word puzzles, Sudoku, nonograms (griddlers), Kakuro, and other logic puzzles. Use a generator when you want a puzzle tailored to a topic, vocabulary list, or difficulty level rather than a ready-made grid.

Generator vs. solver: what's the difference

These two functions are often bundled in the same program, so it helps to separate them.

Cross+A's search tools sit on the solver side — searching English words by known letters and descriptions, finding anagrams and word combinations — while its puzzle-creation features sit on the generator side. A single program can do both, but the workflow and the inputs are different.

What you can generate

Cross+A's puzzle coverage, based on its own listing, includes:

• Crosswords — standard and variation grids
• Anagrams — word rearrangements, in both "descending" and "ascending" directions
• Word puzzles — letter- and word-based games
• Sudoku — number-placement grids
• Nonograms / griddlers — picture-logic grids
• Kakuro and other logic puzzles

The anagram modes are worth understanding because they behave differently:

• Descending search finds all words that can be made from the letters you supply. For the word option, the program returns a list like: point, piton, top, into, tip.
• Ascending search finds all words that contain all the letters you supply. For melody, it returns: electrodynamics, employed, formaldehyde, methodology, polyamide.

That distinction matters when you are generating anagram puzzles: descending gives you short answers from a long prompt, ascending gives you long answers from a short prompt.

Building a puzzle from your own words

The core of generation is supplying the raw material. Cross+A uses a dictionary of 159,000 English words, part of them with descriptions, and lets you add new words, delete or change descriptions, and copy words to the clipboard. Word lists for other languages can be downloaded.

A practical build sequence:

1. Assemble your word list. Either draw on the built-in dictionary or enter your own words — a class vocabulary list, a themed set, or names for a personalized puzzle.
2. Attach clues or descriptions. Words with descriptions can be searched and clued by description; words without them rely on letter patterns or anagram logic. If you want definition-style clues, add descriptions to your entries.
3. Choose the puzzle type. Crossword, anagram, word search, Sudoku, nonogram, or another logic format — each takes a different kind of input.
4. Set the grid and difficulty. Grid size and the number of words you place determine how dense and how hard the result is.
5. Generate, then review. Check that every word fits and every clue matches before you export.

Search modes you can reuse for generation

Cross+A's search modes double as generation tools, because each one produces a candidate word set:

• Search by letters — find a word by known length and letters.
• Anagram search — descending (words from your letters) or ascending (words containing your letters).
• Search by description — use when some words in the target description are known.
• Search by pattern — use wildcard characters to match unknown positions.
• Word-combination search — build combinations from your letters; for example, incredible = nice + bridle.

The word-combination mode is especially useful for crossword construction, where a long answer often needs to break into shorter fill.

Exporting, printing, and sharing

Cross+A's listing points to screenshots, an online help file, and a version history, which is where the exact export and print options live. The general rule for any generator: generate, preview the grid, then export or print before distributing. If you plan to share a puzzle, produce both the puzzle and its answer key in the same pass so the two stay in sync.

Common problems and how to avoid them

Missing words. If a word you expect doesn't appear, it may not be in the dictionary, or it may lack a description. Add it manually — Cross+A lets you add new words and change descriptions.

Unsolvable or over-constrained grids. Too many long words in too small a grid leaves no valid crossings. Reduce the word count or enlarge the grid.

Wrong anagram direction. Getting short answers when you wanted long ones (or the reverse) means you used descending instead of ascending, or vice versa. Match the mode to the puzzle you're building.

Clues that don't match. If you generated from a word list without descriptions, you'll have answers but no definition-style clues. Decide up front whether you need descriptions, and add them before generating.

Language gaps. The built-in dictionary is English; other languages require downloading the corresponding word lists.

Choosing whether a generator fits your task

Pick a generator like Cross+A when you need puzzles built around specific words, clues, or themes, and when you want several puzzle types — crosswords, anagrams, Sudoku, nonograms, logic puzzles — handled by one tool. Stick with a solver-only tool when you just need help finishing puzzles someone else made. If your main need is a single puzzle type, check that the program covers it before committing; Cross+A's coverage is broad, but the exact creation options for each type are documented in its online help and screenshots rather than summarized on the overview page.
