The "Keywords — Codeword Puzzle" app offers an engaging and intellectually stimulating experience by allowing you to solve codeword puzzles. These puzzles are essentially crosswords where each letter is represented by a distinct number. Unlike traditional crosswords, codeword puzzles do not provide clues for the words; instead, players must deduce the correct letters based on the numbers provided. The objective is to uncover the original, uncoded crossword grid.

This application is unique as it combines elements of numerical, word, and logical reasoning into one enjoyable challenge. No matter how long you play, the app ensures that there's always a new codeword to solve. With convenient navigation features, you can easily move around the puzzle grid. All codewords are free, and you can play them offline, although an internet connection is required if you want to access the definitions of the words you've guessed correctly.

The app supports various puzzle sizes, including grids like 12x12, 12x15, 15x15, 15x18, and 18x18, providing ample variety and difficulty levels to keep you entertained. Solved letters are automatically filled in, though this feature can be disabled in the settings if preferred. The app also offers both light and dark themes, allowing you to customize your visual experience according to your preference.

To make the puzzles more manageable, hints are available if you find a particular codeword too challenging. You can also save your progress and return to a puzzle later, or even switch between multiple puzzles simultaneously. Checking your solutions is straightforward, and any letters you've guessed correctly are highlighted for easy reference. Additionally, the app allows you to scale the codewords, key tables, and alphabet, ensuring a comfortable viewing experience. Both portrait and landscape orientations are supported, and you have the option to reveal either a single word or up to five random letters when starting a new puzzle. Lastly, the app provides both standard (ABC) and QWERTY keyboard layouts, along with a range of flexible settings to cater to individual preferences.
