Deduce is a fun way to learn and visualize the process of logical deduction. It’s a uniquely challenging game combining logic, vocabulary, and spelling skills (with a small element of luck) played with words. Your goal is to discover a hidden mystery word with as few guesses as possible. Deduce acts as an assistant who enforces the rules, provides hints, keeps track of your progress, collects statistics, manages saved games, and (for Game Center users) awards achievements. Reviewers have said: "One of my favorite games", "Other games get installed-played-uninstalled, but this one stays", "Challenging and addictive", "Very original and lots of fun", "I'm completely hooked", "Hope I can stop playing it soon!" Features: 1. Many thousands of possible games (more than 20,000) 2. Comfort level - Deduce can be as easy or challenging as you like, with optional features to assist your thinking. Play with easier 5 letter words or more difficult 6 letter words. NEVER ANY ADS TO DISTRACT YOU! 3. Game Center integration. Statistical results, scores, and saved games are associated with the active Game Center player. If you are not logged into Game Center, you may supply your own player name for separate game tracking, or play anonymously. If you use Game Center, scores are reported to Classic, Novice, and Puzzle leaderboards. A Champions leaderboard ranks the overall quality of your play over time. Achievements may be earned based on the quality and persistence of your game play. As you earn Deduce achievements discover 50 19th century literary giants of the western world, who were also masters with words. A portrait medallion, with a biography link, is awarded for each achievement -- collect them all! 3. Mystery Word definitions. When you finish a game of Deduce, a definition of the mystery word is provided. Increase your vocabulary as you play more games. Definitions come from’s Apple’s downloadable dictionaries or Wiktionary, whichever is available. 4. Game records. Save your games automatically or selectively. Create beautifully formatted PDFs of your games for sharing or printing. 5. Preferences. Use the Settings App to specify global options for Deduce, such as autosave (which automatically saves a limited or unlimited number of your completed games). 6. Easy sharing with friends or other devices. Find a game really challenging? You can challenge friends to find the same mystery word by sharing a Deduce game number via Airdrop, Messages, or email. Deduce also plays well on a shared device. Each family member can play using their own name or Game Center account with separate saved games, statistics, and (for Game Center users) achievements. 7. A polished user experience with improved marking and simpler game play. Use letter dials or a keyboard to enter your guesses. On an iPhone, enlarge guess list for easier manipulation.
