The purpose of Cross+A is to simplify the solution of crosswords, word-based puzzles, sudokus, nonograms and other logic puzzles. Cross+A provides very flexible and powerful search tools. User can search English words by known letters and descriptions as well as find anagrams and word-combinations.

This is a multilingual version of the popular Russian program Cross+A by Sergey Kutasov and Ilya Morozov. It uses a dictionary of 159000 English words (part of them has descriptions). Users can add new words, delete and change descriptions or copy words to the clipboard. Cross+A also includes:

• the list of English proverbs and sayings;
• the list of English synonyms and antonyms.

The lists of words for other languages are available for downloading.

Search modes:

• Search by Letters
  Search word by known length and letters.
• Anagram Search
  This mode has two special options:
• "Descending" Search
  Search for all words that can be created from the text letters.
  For example, for the word option the program will find the word-list: point, piton, top, into, tip, etc.
• "Ascending" Search
  Search for all words that include all letters of the text.
  For example, for the word element the program will find the word-list:
  settlement, development, experimental, acknowledgement, electromagnetism, etc.
• Search by Description
  This search mode is used when some words in the target word description are known.
• Search by Pattern
  Search with use of special wildcard characters.
• Word-combination Search
  The program tries to create word-combinations using the text letters.
  For example: incredible = nice + bridle.
• Telephone Number Search
  The program finds word equivalents for the telephone numbers. Telephone number digits are substituted by letters written on telephone set buttons.
  For example: 728-74-68 = PATRIOT.
• Search by Syllables
  The program creates words using syllables from the user's list.
  For example: at,be,e,for = ate, beat, bee, before, fore.
• Coupling Words Search
  Search for pairs of words where the first word ending is equal to the second word beginning.
  For example: ?????(gen)???? = PATHOGEN and GENESIS.
• Trackword Search
  Search for words, which can be made by moving from letter to letter horizontally or vertically in the grid.
• Cryptarithm
  Cryptarithm is an mathematical puzzle involving words where there is a one-to-one mapping between letters and digits that makes the arithmetic equation true.
  For example: MOTHER+FATHER=PARENT   =>   196753+286753=483506.
• Word-chain Search
  Search for chains of words, where every word differs from its neighbours by one or few letters.
  For example: FLY - FAY - FAT - CAT.
