Кейворды Ключворды is a free word puzzle game developed by Anton Kumbralyov for Android. The game is a unique combination of a numeric, word, and logical puzzle game. The puzzle consists of a crossword with each letter replaced by a number. The game's distinctive feature is the absence of word definitions, and each number corresponds to only one specific letter. The goal of the puzzle is to restore the original encrypted crossword.

The game offers several puzzle sizes, including 10x10, 10x15, 12x15, and more, and all puzzles are available for free and can be played offline. If a puzzle seems too challenging, players can use hints to help solve it. The game also offers an auto-fill feature, checks the correctness of the puzzle solution, and highlights the letters that have been filled in correctly. Additionally, players can scale the size of the crossword, the key table, and the alphabet. Furthermore, players can choose to open a word when starting a new puzzle or open up to five random letters.
