The Brain: a free online word search

The brain word search is playable online right now, no account needed, starting with neurons and working toward memory.

About The Brain

The human brain weighs roughly three pounds, yet it contains nearly 86 billion neurons, each one reaching toward its neighbors through a branching web of dendrites and axons. Every thought, memory, and emotion travels as an electrical signal leaping across synapses at breathtaking speed, shaping who we are moment by moment. From the frontal lobe's quiet deliberation to the limbic system's deep tides of feeling, the brain is the most intricate thing we know of in the universe.

How to play

  1. 1
    Find a word.Tap its first letter, then tap along to its last. The trail fills in and finishes itself when it spells a word. Or press the first letter and drag.
  2. 2
    Words run in straight lines.Across and down, and on the harder difficulties diagonally and backwards.
  3. 3
    It marks itself.Each word you find takes on its own soft colour on the grid and is crossed off the list.
  4. 4
    Choose a difficulty.Relaxed, Classic or Challenging set those directions and how much the word list helps, never the grid size. Tap the A buttons at the top to enlarge the letters, or pinch the grid.
