This puzzle looks straightforward, but it is more complex than you think. The figure of 45 is concealed in a grid of two odd numbers: 54 and 55. Can you spot them within 5 seconds?
On initial observation, all the figures seem the same. That is why our brain is programmed to detect patterns quickly and naturally to fill in the gaps. With the same-looking figures, such as 4 and 5, coming in succession, it becomes more difficult for our eyes to detect a slight difference, such as a 4 replacing a 5.
It is an optical illusion that challenges your eye, eye for detail, and visual wit. It appears as though it is a basic puzzle game, but these drills are applied in mind training to hone concentration and acuity of mind.
