The classic guessing game reimagined for voice-first interaction
Sometimes the best ideas are hiding in plain sight. Lucas Hunter discovered this while working on OpenHome personalities and realized that 20 Questions, that timeless guessing game we've all played on road trips, would be perfect as a voice ability rather than a full personality. He was absolutely right.
The 20 Questions ability transforms your OpenHome device into the perfect game partner, thinking of objects for you to guess through strategic yes-or-no questions. It's deceptively simple on the surface but incredibly engaging once you start playing. The AI picks something, you have twenty questions to figure out what it is, and the back-and-forth creates that perfect blend of challenge and satisfaction when you finally crack the code.
This ability showcases something beautiful about voice-first gaming: it strips away all the visual complexity and gets straight to the core of what makes a game fun. Pure logic, deduction, and that moment of triumph when you nail the answer.
What is 20 Questions?
Picture yourself settling into your favorite chair and deciding you want some mental stimulation that doesn't involve staring at a screen. You ask your OpenHome device to play 20 Questions, and suddenly you're engaged in one of humanity's most enduring games, refined for the voice era.
The ability thinks of an object and gives you up to twenty yes-or-no questions to figure out what it is. The magic happens in how it guides the interaction, keeping track of your question count, providing helpful examples when you ask non-yes-or-no questions, and maintaining that perfect game flow that keeps you hooked.
What makes this implementation particularly clever is how it handles the natural language aspect. The ability recognizes when you're asking valid yes-or-no questions versus when you need gentle redirection. It also manages the progression beautifully, counting down your remaining questions and building that sense of urgency as you get closer to twenty.
The game ends either when you make your final guess (by saying "guess" followed by your answer) or when you run out of questions. Getting the answer in fewer questions feels genuinely rewarding, like you've outsmarted the system through strategic questioning.

No setup required, no configuration needed. Just install and start playing immediately.
How It Works
The game kicks off when you ask your OpenHome device to play 20 Questions. The ability immediately thinks of an object and explains the rules: you get up to twenty yes-or-no questions, say "quit" to stop, and say "guess" when you're ready to make your final answer.
Behind the scenes, the ability is managing several important elements. It's selected an object from its knowledge base, it's tracking your question count in real time, and it's parsing your questions to determine if they're properly formatted as yes-or-no inquiries. When you ask something like "How big is it?" the ability gently redirects you with examples of proper yes-or-no format.
The interaction flow feels natural and conversational. You ask "Is it smaller than a mouse?" and get back "No, you have 19 questions remaining." The ability keeps you informed of your progress while maintaining the game's momentum. There's no awkward pausing or confusion about whose turn it is.
When you're ready to make your final guess, you say "guess" followed by your answer. The ability immediately tells you if you're correct and how many questions it took you to solve it. In the demo, the answer was "skateboard" and the player nailed it in just six questions through smart deductive reasoning.
How It Was Built
Lucas built this using OpenHome's development tools, focusing on the core game logic rather than complex integrations. The brilliance is in the simplicity: managing state for question counting, object selection, yes/no question validation, and natural conversation flow.
The technical implementation handles several key challenges. The ability needs to recognize various ways people might phrase yes-or-no questions, validate that questions are properly formatted, and provide helpful guidance when they're not. It also manages the game state throughout the session, tracking remaining questions and maintaining the selected object consistently.
One of the more interesting aspects is how the ability handles the object selection. It needs to choose items that are neither too obvious nor impossibly obscure, creating that sweet spot where the game feels challenging but fair. The ability also has to be prepared to answer yes-or-no questions about virtually any property of the chosen object, from size and color to function and context.
The question validation system is particularly well thought out. Rather than just rejecting improperly formatted questions, the ability provides helpful examples and gently guides players back to the yes-or-no format. This keeps the game moving smoothly while teaching proper gameplay mechanics.
How to Use It
Getting your 20 Questions session started takes seconds:
Find the ability: Search "20 Questions" in the OpenHome marketplace
Install it: Click install to add it to your account
Start playing: Ask your OpenHome device to play 20 Questions
Ask strategic questions: Use yes-or-no questions to narrow down possibilities
Make your guess: Say "guess" followed by your answer when you think you know
The key to winning is strategic questioning. Start broad (Is it alive? Is it man-made? Is it bigger than a breadbox?) then narrow down based on the answers. The ability will keep you informed of your remaining questions and gently correct you if you ask non-yes-or-no questions.
For the best experience, think like a detective. Each question should eliminate as many possibilities as possible. The demo shows this perfectly: starting with size, moving to color, then functionality, and finally transportation, leading to the correct "skateboard" answer in just six questions.
Why It Matters
This ability demonstrates something important about voice-first gaming: sometimes the most engaging experiences are the simplest ones. No graphics, no complex controls, no visual interface needed. Just pure human reasoning and deduction facilitated by natural conversation.
The 20 Questions ability also showcases how classic games can find new life in voice computing. This isn't just a digital recreation of an old game; it's the game perfected for its ideal medium. Voice interaction eliminates all the friction and gets straight to the fun part: the mental challenge and the satisfaction of logical deduction.
Beyond entertainment, abilities like this highlight how AI can facilitate genuinely engaging human experiences without trying to be the star of the show. The AI isn't showing off its knowledge or trying to impress you with complex responses. It's simply being a great game partner, managing the mechanics so you can focus on the strategy and fun.
Watch the Walkthrough
The demo video perfectly captures how natural and engaging the 20 Questions experience feels. You can hear the smooth flow from game setup through strategic questioning to that satisfying moment of solving the puzzle. Lucas walks through the entire interaction, from the ability's clear rule explanation to the final correct guess of "skateboard."
What comes through clearly in the walkthrough is how the ability maintains perfect game flow while providing helpful guidance. When questions aren't properly formatted, it doesn't break the experience but instead offers gentle correction with examples. The question counting feels natural and informative rather than mechanical.
The video also demonstrates the strategic thinking that makes 20 Questions so engaging. Starting with broad categories, then narrowing down through logical deduction, building toward that moment when all the pieces click together and you know you've got the answer.
Challenge Your Deduction Skills
The 20 Questions ability represents voice-first gaming at its finest: simple to understand, endlessly replayable, and genuinely satisfying to master. Lucas has created something that proves the best digital experiences often come from perfecting timeless concepts rather than reinventing everything from scratch.
Ready to test your deductive reasoning and see how few questions you need to crack the code?
