If you like crosswords or word games, then you'll love Unolingo, a fun and unique twist on a traditional crossword puzzle. Every Unolingo puzzle is a 10 x 10 crossword without clues and 26 empty squares that require the precise placement of each letter in the alphabet. What a Sudoku puzzle does using numbers, Unolingo does using each letter of the alphabet! Select from your choice of four difficulty levels and use your word knowledge, reasoning, and deduction skills to complete the puzzle. Each puzzle is hand-crafted from a carefully curated list of common English words more likely to be heard at a party with friends than in the classroom. This fascinating word puzzle can generally be completed in 5-15 minutes and is fun for the daily commuter, the casual puzzler, or the serious word buff. Features: - 20 free introductory puzzles offering hours of enjoyment, with additional puzzle packs and series available as in-app purchases. - Unique hint and audit functions to help you solve the most difficult puzzles. - A bonus puzzle when you tell a friend about Unolingo by email. - Flexible design supports casual play, collaboration with friends, or time-based challenge. - Extensive performance statistics to monitor your progress and improvement over time.

Can you crack the code? Astraware CodeWords is an addictive word puzzle game with a difference! You start with a crosswords style grid but instead of words, each letter has been substituted with a number from 1 to 26. It is up to you to figure out which number stands for each letter! There are no clues but 3 letters are already in place to help you get started and each letter of the alphabet is used at least once. You start by guessing possible words and matching numbers with letters, until you've fully cracked the code - and your vocabulary and logical reasoning will be stretched along the way! Did you know that the letter 'e' is the most commonly used letter in English? Did you know that 'th' is the most common pair of letters to be seen together? You'll use this knowledge and more as you make your guesses and work out the words! Astraware CodeWords gives you access to play our free Daily puzzles - top the global leaderboard by completing the puzzle in the fastest time! For an extra challenge there is a Weekender puzzle available each Friday with a trickier grid and more unusual words. Great features include: - Unlimited access to our two Daily puzzles and Weekender puzzle. - A collection of 50 built-in puzzles in various sizes and difficulties, perfect for beginners and avid players - Extra puzzle streams for endless play - Intuitive interface - Highlighting to show where you've chosen the same letter for different numbers - Option to fill in letters manually, or choose auto to fill in all occurrences of that letter at once - Save slots available to have several puzzles on the go at once, so you can stop for a break and come back to a puzzle later - Option to purchase extra value puzzle packs for offline play - Puzzles Plus subscription for unlimited puzzles Puzzles Plus Subscription Terms and Details Puzzles Plus is our optional subscription for CodeWords which entitles you to play all of the available Daily, Weekender and Stream puzzles as soon as they are available, without in-game adverts or any requirement to earn tokens.
