Optical Illusion Eye Test Challenge: Within 7 Seconds Spot The Number 51 and 61 among 41 - Solution

In this optical illusion puzzle, almost every blue circle contains the number 41, but two circles secretly display different numbers: 51 and 61.

The number 51 is hidden in the upper half of the grid, slightly left of centre, where the first digit changes from 4 to 5 while the position of the 1 remains the same, making it easy to miss at first glance.

The number 61 is located in the lower portion of the image, more towards the left side, where again only the first digit differs from the surrounding 41s, blending cleverly into the repetitive pattern and challenging your focus and attention to detail within the 7‑second limit.
