Token Forge

Token Forge is a daily word game with a twist: the letter-tiles aren't letters – they're BPE tokens, the same sub-word fragments that AI language models use to read text.

Each day brings a new plate of tokens. Combine them into real words: the more you find, the higher your score. Complete the plate to unlock the bonus round.

THE BONUS ROUND – BECOME AN ATTENTION HEAD
Ever wondered how an AI model actually understands a sentence? In the bonus round, you find out by doing it yourself. Given a sentence with one highlighted word, you spread 100 attention points across the other words to show which ones matter most for understanding it – exactly what happens inside a language model. Each puzzle teaches a real pattern: how pronouns find what they refer to, how verbs reach for their subjects, how comparatives need both sides.

FEATURES
• A fresh plate every day for a year, 366 per language
• Two languages: English and Swedish, each with its own puzzles and streaks

Every word is checked against a standard dictionary. Proper nouns and abbreviations aren't accepted; uncommon-but-real words are recognized as rare finds.
