Ba Ba Dum: learn 1500 words in 21 languages by picture

Ba Ba Dum is a free browser game that teaches 1500 words across 21 languages by matching each word to a hand-drawn picture, with no ads, no paywall, and no signup required to play. It is worth a look because it does one small thing, vocabulary, with more craft than most paid apps manage.

There is no course to finish, no streak to protect, and no subscription to cancel. A visitor picks a language, picks one of five games, and starts clicking. The whole thing loads in a browser tab and asks for nothing in return.

In brief

• Ba Ba Dum teaches 1500 words in 21 languages through five short picture-matching games, all free.
• It was built by Aleksandra and Daniel Mizielińscy, Polish illustrators who drew every image by hand.
• Playing needs no account; signing in only saves your score and progress.
• It teaches vocabulary, not grammar or conversation, and is honest about that narrow scope.

What Ba Ba Dum actually is

The site is a collection of five HTML5 games that drill foreign vocabulary. Each round shows a word, a picture, a sound, or some combination, and asks the player to pick the matching option from four choices. Get it right and the next card appears. There is no lesson, no explanation, and no narrator. The learning happens through repetition and recognition.

According to the makers' own project page at oladaniel.com, the game covers roughly 1500 words across 21 languages. The word list leans concrete: animals, food, tools, colors, body parts, verbs you can draw. Abstract nouns are mostly absent, because an abstract noun is hard to illustrate without ambiguity.

That constraint is the whole design. A picture can stand in for the word in any language, so the same 1500 drawings serve every language the site supports. The player never sees a translation into their own tongue. They see a cat, and they learn the word for cat in Polish, Japanese, or Portuguese by association rather than by lookup.

Everything runs client side in an HTML5 canvas, so there is nothing to install and no app store in the way. The site loads, the drawings appear, and play starts within a second or two. That immediacy is part of why it spread: a link is all it takes to try it, which is rare for anything in the language-learning category.

The five games

The five modes are variations on the same matching idea, each training a slightly different skill. The review at Laughing Squid and the discussion threads describe them consistently.

Picture from a written word

The game shows a written word and four pictures. The player picks the illustration that matches. This is the gentlest mode, useful for a first pass through a new language where reading comes before listening. It builds the initial link between a shape of letters and a thing in the world.

Picture from a spoken word

Here the game plays an audio clip of a native speaker and shows four pictures. No text appears. The player has to recognize the word by sound alone, which is harder and closer to how a language is actually heard in the wild. For learners whose ear lags behind their reading, this is the useful struggle.

Written word from a picture

This reverses the first mode. The game shows one picture and four written words, and the player selects the correct spelling. It tests recall of the written form rather than simple recognition, and it quietly teaches which near-identical words are easy to confuse.

Spelling

The toughest mode shows a picture, plays the audio, and asks the player to spell the word by arranging or typing letters. There is no multiple-choice safety net, so it rewards players who have genuinely absorbed the word rather than guessed it. It is also where an unfamiliar alphabet stops being decorative and starts being something you can produce.

Mixed

The fifth game shuffles the other four. One card might be audio only, the next a picture with four words. The unpredictability keeps a session from settling into a rhythm, which is where attention tends to drift. It is the closest the site comes to a test rather than a practice.

Every mode tracks points, and the site keeps a simple scoreboard. Signing in saves that progress across sessions, but it is optional. A visitor who never logs in can still play every game in every language.

No account, no friction

The design choice that dates best is the absence of a wall. Ba Ba Dum does not demand an email address before the first round, does not interrupt play with a prompt to upgrade, and does not run advertising. The makers confirm on their page that the game is free and carries no ads. In 2026 that restraint reads almost as a statement.

Signing in exists only to persist a score and resume where a player left off. It is a convenience, not a gate. Nothing about the actual learning is locked behind it, which means the barrier between curiosity and playing is as close to zero as the web allows. For a project that depends on word of mouth, removing that barrier is the most important feature it has.

The scoreboard supplies the only external motivation, and it is gentle. Points accumulate, and a player can glance at how others are doing, but there is no daily guilt mechanic engineered to pull them back. The game trusts that matching pictures to words is pleasant enough on its own, and for a surprising number of people it is.

Who built it

Ba Ba Dum is the work of Aleksandra and Daniel Mizielińscy, a husband-and-wife studio based in Warsaw. They are better known as illustrators and authors of children's books, most famously the large-format illustrated atlas titled Maps, an international best seller translated into many languages. The game shares the same visual sensibility: dense, warm, slightly handmade.

They released Ba Ba Dum in 2014. The project was submitted to Hacker News under the plain title "A game to learn a new language," where it drew 75 points and a long thread of comments, archived at news.ycombinator.com. Readers praised the interface and the obvious care in the artwork, and several argued about whether vocabulary drills count as real language learning. More on that argument below.

The Mizielińscy pair treat the site as a side project rather than a business. There is no venture funding visible, no upsell, and no premium tier. The makers describe it simply as something they built and chose to give away, which is consistent with a studio whose main output is print, not software.

The illustrations, drawn on paper

The art is the reason the game feels different from a flashcard app. Every one of the roughly 1500 images was drawn by hand on paper with markers, then scanned and converted to vector graphics. The creators note on their project page that they drew far more than they used, picking the final 1500 from thousands of sketches.

Each category of word carries its own color scheme. Nouns, adjectives, verbs, colors, body parts, and countries each get a distinct palette, so a player builds a loose visual memory of where a word sits as well as what it means. The effect is closer to a picture book than a quiz, which is probably the point given the makers' background.

Hand-drawing the set also solved a translation problem. A photograph of a specific dog implies a specific breed, a specific place, a specific moment. A simple drawing of a dog reads as the idea of a dog, which travels better across 21 languages and cultures. The abstraction is doing quiet work.

There is a practical payoff too. Because a single illustration serves every language, the makers only had to draw the set once, then attach a word and an audio clip per language. The art is the expensive, reusable core, and the translations are the cheap, extensible layer on top. That architecture is why the project could keep adding languages for years.

A typeface built for 21 alphabets

Supporting 21 languages means supporting several writing systems, and off-the-shelf fonts rarely cover them all with a single consistent look. So the Mizielińscy pair drew their own. The typeface, named Mr Dum Dum, is an OpenType font in two styles that covers Latin letters with diacritics, Cyrillic, Greek, Japanese hiragana and katakana, and simplified Chinese characters.

That is an unusual amount of effort for a free game. Most projects would have shipped three fonts that did not quite match and moved on. Building one family that handles Warsaw, Athens, Tokyo, and Beijing in the same visual voice is the kind of detail that users never consciously notice and always feel.

The language list itself grew through goodwill. The makers say almost every language beyond the first nine was suggested, translated, and verified by friendly institutions and by players who volunteered. That is how a two-person studio reached 21 languages without a translation budget.

A quiet alternative to the streak

Commenters in the Hacker News thread reached naturally for a comparison with Duolingo, the category's dominant app. The contrast is instructive. Duolingo is built around retention mechanics: streaks, reminders, leaderboards, and a cartoon owl that notices when you stop. Ba Ba Dum has none of that, and the omission is deliberate.

The trade is real. The retention machinery is why millions of people keep opening Duolingo, and its absence is why Ba Ba Dum is something people rediscover rather than return to daily. But the absence is also the appeal. There is no manufactured anxiety, no sense of a debt owed to an app. A player opens it when they feel like it and closes it when they are done.

For learners who have bounced off gamified apps precisely because the pressure felt manipulative, that is a feature. Ba Ba Dum treats attention as something to be earned by being pleasant, not extracted by being sticky. It is a smaller ambition, honestly held.

What it is good for, and what it is not

The honest case against Ba Ba Dum was made in its own Hacker News thread. A former language teacher argued that learning words is not the same as learning a language, and that time spent memorizing nouns can crowd out the grammar, listening, and speaking that actually make a person conversational. It is a fair point, and the game does not pretend otherwise.

Ba Ba Dum teaches recognition vocabulary. It will not teach how to conjugate a verb, build a sentence, or hold a conversation. Commenters also noted that it omits grammatical gender, which matters a great deal in German, Spanish, and other gendered languages where the article is part of the word.

What it does well is the first mile. Building a base of concrete nouns is genuinely useful early on, and doing it through a game that is pleasant to open beats grinding through a deck of index cards. Several teachers in the threads recommend it as a warm-up or a supplement, not as a full curriculum, and that framing fits what the site is.

For a casual visitor with no intention of becoming fluent, the calculus is simpler. Ten minutes of matching cats and bicycles to Finnish words is a small, complete pleasure. It asks nothing, teaches a little, and leaves the tab closable without guilt. There is also a quiet case for it as a travel primer: a few sessions before a trip leave a visitor able to recognize the words for coffee, bread, exit, and ticket, which is often all a short stay demands.

How to get the most out of it

Players who want more than idle fun tend to follow a pattern. They start in the written-word mode to meet the vocabulary, move to the audio mode to attach sound to each word, and only then attempt spelling. Treating the five games as a difficulty ladder rather than a menu turns a toy into a short, effective drill.

Because the site asks for no commitment, it also works as a daily habit the way other single-purpose sites do. A short session each morning, one language, one game, compounds more reliably than an hour-long binge once a month. The same instinct drives the wider family of quiet, do-one-thing sites collected at Boring Websites: a small ritual beats a grand plan.

It pairs naturally with a tool that teaches the grammar it skips. The teachers in the Hacker News thread were not dismissing Ba Ba Dum so much as placing it correctly. Used as the vocabulary layer underneath a proper course, the game earns its keep. Used alone, it is a charming way to learn that the Polish word for butterfly is motyl and little else.

FAQ

Is Ba Ba Dum free?

Yes. The game is free to play, carries no advertising, and does not sell a premium tier. Playing requires no account. Signing in is optional and only saves a player's score and progress across sessions, as described on the makers' page at oladaniel.com.

How many languages and words does it cover?

The site offers roughly 1500 words in 21 languages, played through five mini-games. The word list favors concrete, drawable things, and the same set of hand-drawn illustrations is reused across every language. You can try any of them at babadum.com.

Can Ba Ba Dum make someone fluent?

No, and it does not claim to. It teaches recognition vocabulary, not grammar, sentence structure, or conversation. Language teachers in its Hacker News thread recommend it as a supplement or warm-up rather than a complete course, since real fluency needs speaking, listening, and grammar practice it does not provide.

Who made it?

Aleksandra and Daniel Mizielińscy, a Polish illustrator couple based in Warsaw, known for the best-selling children's atlas Maps. They built Ba Ba Dum in 2014, drew every illustration by hand, and even designed a custom typeface, Mr Dum Dum, to cover the many alphabets the languages require.

How does it compare to Duolingo?

It is narrower and quieter. Duolingo wraps a full beginner course in streaks, reminders, and leaderboards designed to pull a learner back daily. Ba Ba Dum drops all of that and does one thing, vocabulary through pictures, with no pressure to return. Commenters in its Hacker News thread treat the two as complements rather than rivals: Ba Ba Dum for the words, a structured course for the grammar.
