A free app for Android, by Astraware Limited.
Astraware CodeWords is a word game that will challenge your mind and vocabulary. You start with a crossword-style grid but instead of words, each grid square has been replaced with a number from 1 to 26. It is up to you to figure out which number stands for each letter in the code!
The game is easy to play but has a number of challenging puzzles. You can complete them all in a single day if you are careful and thorough. But if you're not ready to spend all day solving puzzles, you can also play the game in a couple of minutes.
Each puzzle has a number of clues. With them, you can get a better idea of what the puzzle is about. But you can also use your own logic and imagination to solve the puzzle.
