Typoglycemia test

Word Decoding Challenge

Sharpen your brain with four fast-paced word recognition games. Each mode tests a different aspect of your visual and linguistic processing. Your goal: decipher the altered text as quickly and accurately as possible. Type the correct words, rack up your score, and see how fast your brain really is.

Game 1: Typoglycemia (Scrambled)

Based on the phenomenon of typoglycemia, this mode scrambles the letters in the middle of each word while keeping the first and last letters in place. Surprisingly, your brain can still read the jumbled text—until the timer runs out. Can you decode the chaos?

Game 2: Top/Bottom Occlusion

Challenge your visual system by hiding either the top or bottom half of each word (e.g., 50% occlusion). You'll need to rely on partial shape and contextual clues to reconstruct what you're seeing. Can your brain fill in the blanks?

Game 3: Random Letter Occlusion

Letters randomly vanish within each word, forcing you to mentally reconstruct words from broken fragments. This game hits your pattern recognition hard—perfect for testing mental flexibility and linguistic intuition.

Game 4: First/Last Letter Occlusion

The opposite of Typoglycemia: here, the first and last letters are hidden, and only the middle remains. Without the usual anchors, reading becomes a true test of word familiarity and cognitive guesswork.
