Typoglycemia play online

This application is a letters mixer. It scrambles the letters in the words.
The application demonstrates a condition called Typoglycemia - cognitive processes behind reading written text.
Readers can understand the meaning of words in a sentence even when the interior letters (excluding the first and the last ones) of each word are scrambled. This is because the human mind does not read every letter by itself, but the word as a whole.

You can easily paste text and copy scrambled version of it. There is "Hide" button which hides original text so you can challenge someone to read the text with scrambled letters.
