3.4

September 16, 2015

Caution: Deduce 3.4 requires iOS 8 or later! It features the following improvements:
 • Full iOS 8 support, and tested with iOS 9 betas. • Native support for iPhone 6, 6 Plus, and future models, using autolayout techniques. • Greatly improved performance. • Fixes for many small, but annoying bugs. • A new reset button offers a convenient way to clear the input staging area when using the letter dials or the software keyboard. • For iPhone and iPod users, a small button near the upper left of the list of guesses makes it simple to enlarge (or shrink) the list for easier tapping on individual letters. • If you were using the Autosave feature to automatically save each of your completed games, go to the Apple Settings app, scroll down the list of apps on the left until you find Deduce, then switch the Autosave button off and back on again. This will re-activate the Autosave feature. Note that autosaved games show up in the Deduce Game Manager section, and do not include games that you resign (unless you choose to save them manually yourself). • You may notice that we removed the “floating words” option. That feature is now redundant. Use the Suggest button to find words matching specific patterns, or tap on Sherlock in the Menu dialog to see a random list of words in the backdrop. • And finally, some news: we expect to be able to restore Deduce’s multiplayer capability with the future release of Deduce 4.

3.01

September 24, 2013

Note to users running prior versions of Deduce with iOS 7: due to an unfixed Apple defect in iOS 7, arbitrary sequences of letters may be accepted as guesses. A work-around in the iOS 7 version of Deduce fixes this; please upgrade to the latest version of Deduce (3.01). Ignoring Game Center login also fixed with this release (3.01). Deduce 3.0 & 3.01—Now completely re-imagined for iOS 7! Starting with our new icon featuring the master of deduction, Deduce 3.0 sports a lighter, more intuitive look and feel, and many new features including: • A new puzzle form of Deduce. Since the words you need to discover the Mystery Word have been preselected, it's a great way to visualize the logical implications of a choice while learning the mechanics of proposing or eliminating letters. • Easier game play. A greatly enhanced Suggest button is available whenever you have trouble thinking of a possible word, but it comes with a price! Each suggestion you request lowers your potential score. Also, you may now manually reorder your guesses to keep related words or hit counts together as the game progresses. • Better layout and arrangement of game controls, particularly when played on an iPhone or iPod Touch. • More ways to save, manage, and share your game experience. • Tap Sherlock whenever you need advice or encouragement. • Optionally use one of your own images as the backdrop for your game play, with included iOS 7 motion effects. A temporary restriction in this new version: multi-player mode has been disabled. Not many of you have been using it, and we think we know why! Look for a significantly enhanced multi-player capability in a free future upgrade. It's now easier than ever to rate or review Deduce (first, sign in to Game Center, then from Deduce, tap Menu->Game Manager->Player->Leaderboards and select your choice of stars). Let us know what you think of the changes and particularly the new Deduce Puzzles. Enjoy! And let us know if there are other features you would like to see in future releases.

Price History of Deduce

Description of Deduce

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. Reorder your guesses to see more potential patterns. Having trouble thinking of words? Use the Suggest button! Need advice about your game play? Tap on Sherlock for tips and encouragement. And check out the help info to learn about letter frequencies and common suffixes. 8. Select your favorite photo as a backdrop for playing Deduce, or use one of our two built-in backdrops.

Reviews of Deduce

  • A great word game

    Really challenging and an exercise for the mind. A prettier interface and the ability to guess 4, 5, and 7 and 8 letter words would make it a five star review.
  • Excellent word game! Fresh idea.

    I've had this game on my idevices for many years, and I always come back to it. Definitely gets your brain working!

    Fun game, simple UI, great options for play! No ads or anything annoying. Really well developed!

    Can be as challenging as you want: Can be incredibly difficult or nearly mindless, it's up to you. Just a truly fine game!
  • To the man I met at Epcot

    I don't remember your name, but we talked in the England section in Epcot and you told me you had made a game, so I downloaded it and I love it! So hard but yet challenging and engaging. Thanks for the awesome app! :)
