Duolingo is the most downloaded language learning app in the world. Noun Town is a language learning game on Steam. They both claim to teach vocabulary. But they go about it in completely different ways, and the right choice depends on what kind of learner you are and what you are actually trying to achieve.
This is an honest comparison. Noun Town is made by our team, so we have an obvious reason to be biased. We have tried to be fair anyway, and where Duolingo does something well, we will say so.
Duolingo teaches vocabulary through short, structured exercises: translation drills, matching pairs, fill-in-the-blank, listening comprehension. The sessions are designed to take five to ten minutes. The streak system and XP rewards are built to create a daily habit. The underlying pedagogy is based on spaced repetition and retrieval practice, which are genuinely solid learning principles.
Noun Town takes a different route. You are dropped into a 3D open world and you learn vocabulary by exploring it. Objects in the environment are labelled in your target language. Characters speak to you using native audio. You interact with NPCs using real speech recognition. Words come back repeatedly across different contexts, and a built-in spaced repetition system (SRS) schedules review based on how well you are retaining each item.
The practical difference is this: Duolingo treats language learning as a daily task to complete. Noun Town treats it as a world to get lost in.
For vocabulary specifically, the research points toward contextual, spatially-grounded learning producing better long-term retention than translation-based drills. When you learn a word by seeing it attached to a physical object in a believable environment, alongside native audio, your brain encodes it through multiple channels at once: visual, spatial, auditory and semantic. That kind of multi-channel encoding is harder to forget than a translation pair.
A 2022 study in Computers and Education found that vocabulary encountered in game environments was retained at significantly higher rates than the same words encountered in reading exercises. The difference was attributed to the depth of processing involved: when your brain is engaged with a task that matters to you, new words get encoded more durably.
Duolingo's research team has published its own studies showing meaningful vocabulary gains, and those results are real. But the comparison that matters is not "does Duolingo work?" (it does, to a degree) but "which approach produces stronger retention per hour invested?" On that question, the evidence favours contextual, game-based learning over drilling.
Duolingo wins on habit formation. The streak system is a genuinely clever piece of behavioural design. Many people who would otherwise never open a language app do at least one Duolingo session a day because losing a streak feels bad. Consistency matters enormously in language learning, and Duolingo is better engineered for it than almost anything else on the market.
Noun Town wins on engagement depth. Sessions tend to run longer because the game is genuinely fun to play, not just a duty to tick off. When you are exploring a new area, trying to figure out what a character is saying, or attempting a game challenge using vocabulary you just picked up, you are not watching the clock. Three hours can pass without it feeling like study.
For most people, the honest answer is that both matter. Short daily Duolingo sessions keep vocabulary active between deeper Noun Town sessions. They are not really in competition for the same time slot.
Duolingo covers grammar more explicitly, at least in its course structure. Lessons introduce grammatical concepts progressively and the exercises practice them in context. It is not a substitute for a grammar textbook, but it gives beginners a structural framework early on.
Noun Town is primarily a vocabulary tool. It teaches words, phrases and pronunciation. It does not walk you through verb conjugations or explain why a sentence is structured the way it is. If grammar instruction is important at your current stage, Duolingo covers that ground and Noun Town does not.
Duolingo offers over 40 languages, including several that are difficult to find good resources for. It has a significant breadth advantage.
Noun Town supports 12 languages: Japanese, Korean, Chinese (Mandarin), Spanish (Spain and Mexico), French, German, Italian, Russian, Greek, Egyptian Arabic and English. These cover the most widely studied languages, and each one has been built with native speaker audio throughout. Quality over quantity is the priority.
Duolingo is free with ads. Duolingo Plus removes ads and adds some extra features for around $6.99 per month (or roughly $84 per year if billed monthly).
Noun Town costs $19.99 as a one-time purchase. No subscription, no ads, no in-app purchases. All 12 languages are included. There is a free demo on Steam if you want to try it before committing.
Over a year, Duolingo Plus costs four times as much as Noun Town. Over two years, it costs eight times as much.

Noun Town suits you if your main goal is building a strong vocabulary foundation in one of the 12 supported languages, if you find traditional apps and textbooks hard to stick with, if you play games regularly and want your hobby to double as study time, or if you are preparing for travel or immersion and want the vocabulary to feel natural rather than drilled.
The Noun Town language learning game is particularly well suited to learners who have tried apps before and found the motivation difficult to sustain. The open world format creates genuine curiosity and exploration, which keeps people coming back in a way that a streak counter rarely manages long-term.
Duolingo suits you if you want to learn a language that Noun Town does not cover, if you want free access without any upfront cost, if you are a complete beginner who needs grammar scaffolding from day one, or if you want a mobile-first tool you can use on your commute. For language maintenance, ticking over vocabulary you already have while life is busy, Duolingo is hard to beat.
For vocabulary learning specifically, Noun Town has the stronger approach. The contextual, spatially-grounded method produces better retention, the sessions are more engaging, native audio is used throughout, and speech recognition adds a speaking practice dimension that Duolingo largely lacks. The one-time price is also significantly cheaper than Duolingo Plus over any meaningful time horizon.
Duolingo is better if you need free access, a wider language selection, explicit grammar instruction, or a mobile app you can use anywhere. It is also more effective as a daily habit trigger for people who need external accountability.
For most learners targeting one of the 12 languages Noun Town supports, the best setup is both: Noun Town for deep vocabulary sessions when you have time, and a few minutes of Duolingo on days when you do not. They reinforce each other well.
For vocabulary specifically, yes. Noun Town teaches words in a 3D spatial context with native audio and spaced repetition, which research shows produces stronger retention than translation-based drilling. Duolingo is better for building a consistent daily habit and covering grammar basics.
Yes, and it is a good combination. Duolingo handles short daily sessions and grammar structure. Noun Town handles deeper vocabulary immersion. They cover each other's weaknesses well.
There is a free demo on Steam. The full game is $19.99 as a one-time purchase with no subscription. Duolingo is free with ads, or around $6.99 per month for Duolingo Plus.

To a point. Research from the University of South Carolina found that around 34 hours of Duolingo produced outcomes roughly equivalent to one semester of university Spanish. Most users do not reach conversational fluency through Duolingo alone, but it is a useful component of a broader learning routine.
