You’ve got eagle eyes if you can spot the hidden number in this optical illusion

IF YOU can spot the hidden numbers in these optical illusions, you’ve got a keener eye than most.

Two digits are obscured by colourful lines and patterns in each of the four images – which get progressively easier as you go.

Each of the designs, which were put together by online games website Jackpotjoy, is hiding the same secret number.

The platform says that it quizzed 100 people to find out how difficult each puzzle is.

The first features a spiralling blue and yellow pattern and is apparently the trickiest of the bunch.

Only one in ten people were able to spot the hidden number in that illusion, Jackpotjot says.

The second illusion – which features a jagged blue and white motif – is a little easier, though few people can solve it.

Around a third of those surveyed were able to find the hidden number in that one, Jackpotjot says.

Two final illusions are easier still.

One features a splodgy, multicoloured pattern and was apparently solved by half of those who tried it.

The final one of the bunch hides the number among wavy black and blue lines.

Nine in ten people can find the number in that one if they look for long enough, the games website says.

Jackpotjoy’s Alex Fagelson said: “A hint to crack these tricky illusions is to zoom out or make the images smaller.

Suddenly the secret number will be revealed! Good luck to everyone who cracks these tricky puzzles.
