Fun Facts

• The 'typoglycemia' effect — reading scrambled words easily when first and last letters are correct — went viral via a 2003 internet meme falsely attributed to Cambridge University research.
• Actual research by Keith Rayner et al. (2006) showed that typoglycemia only works well for short words; words over 7 letters with scrambled middles significantly slow reading speed.
• The human brain processes about 200-300 words per minute during normal reading, using pattern recognition rather than letter-by-letter decoding — which is why mild scrambling still works.

FAQ

What's typoglycemia?

The claim that you can read words with middle letters scrambled as long as the first and last letters are correct. Studies show partial truth — short or common words yes, uncommon words less so.

Are the results always readable?

Depends on word length and familiarity. 3–4 letter words are basically unchanged. 8+ letter words become noticeably harder.

What's the seed for?

Reproducible scrambling — same seed, same scramble. Useful for puzzle design or controlled experiments.

Does it preserve punctuation?

Yes — only internal letters shuffle. Punctuation, whitespace, and numbers stay in place.
