it's like scrabble but worse

can't play that, it's a real word!

Word Meaning

What's all this, then?

BLABRECS is a rules modification for the wordgame SCRABBLE that swaps out the dictionary of real-if-obscure English words for a capricious artificial intelligence. In BLABRECS, real English words aren't allowed! Instead, you have to play nonsense words that sound like English to the AI. These nonsense words are called – you guessed it – BLABRECS.

How do I play?

Get together your regular SCRABBLE supplies and pull up this page in a web browser. Then play SCRABBLE as normal, but before you play a word, use the "test a word..." box at the top of the page to check whether the AI will let you play it. Remember, you can only play words that the AI approves!

When you find a legal word to play, hit the "Play It" button to add this word to the lexicon. As you play, you can write in definitions for all the words you've invented in the "Meaning" textbox next to each word.

I found a real word that the AI thinks is playable! What should I do?

This happens often with proper nouns (which SCRABBLE generally disallows) and with inflected forms of base words that are disallowed. I think you should play by the spirit of BLABRECS and not the letter, but what this means is ultimately up to you. Is the game primarily about exploring the vast "shadow English" implied by the statistical distribution of letter sequences, or is it about the inherent absurdity of an external authority presuming to dictate your language to you? Either interpretation seems valid to me.

How does the AI work?

The current version of BLABRECS has two AI judges that you can switch between. Source code for both is available if you want to learn more. You can also check out our NeurIPS 2023 paper for a detailed writeup.

The original judge uses a Markov chain trained on the ENABLE word list used in a number of wordgames. It looks at the statistical patterns of letter sequences in English words and uses this information to determine how likely a sequence of letters is to be a real English word. Then it rejects both real dictionary words and fake words that it deems insufficiently plausible.

The second judge, contributed by Isaac Karth, uses a convolutional neural network trained on a substantially larger word list. The features that this judge uses to evaluate words are a bit more opaque, but still ultimately statistical in nature.

I might update BLABRECS to provide a wider range of AI "opponents" using a variety of different technologies in the future. Stay tuned!

Why is it called BLABRECS?

I generated every possible permutation of the word SCRABBLE and asked an early version of the AI to sort them from least to most statistically likely. BRABLECS won out by a significant margin, beating not only the real word SCRABBLE but also my hand-designed previous title BESCRALB. Then I switched the L and the R because BLABRECS sounds better and I'm not about to let a computer tell me what to do.
