Optical illusion: Can you spot the hidden word ‘ball’ in just 10 seconds?
A viral optical illusion asks players to find the hidden word ‘ball’ among multiple rows of ‘bill’ in just 10 seconds.
Optical illusions are the new social media favorite, with many users gravitating towards these visual puzzles. The internet has become a repository for optical illusions, with several users challenging each other. In today’s viral game, players get yet another exercise of finding the odd word out in the grid of a similar-looking word.

Optical illusion: What to do?
The challenge, this time, is deceptively simple: find the word ‘ball’ hidden in a grid full of the word ‘bill’. At first glance, the puzzle looks like a repetition of the same word. But a closer inspection reveals a subtle difference. The catch is you only get 10 seconds to crack this one.

Optical illusion: What to look out for
The trick to solving this optical illusion in under 10 seconds is to look at each word carefully, especially the middle letters of each word, instead of looking at the entire grid, since the words ‘bill’ and ‘ball’ only differ by the second letter.
Focusing on the very shapes of the letters reveals how the rounded curve of the ‘a' will stand out slightly more compared to the straight line of ‘i’. Moreover, instead of taking in the entire picture once as a whole, it would be better to scan it in quadrants.
Optical illusion: Answer
