HERE is another fun brain teaser to test your eyesight and powers of logic.

Everyone can see the ice skater on the rink – but only those with 20/20 vision and high IQ can spot the mistake in the image within seven seconds.

The ice-skater in the picture is clearly having a good time.

You can tell by the grin spread across her face.

Her arms are outstretched as if she is gliding along.

The hundreds of empty seats in the background suggest it could be after hours.

Or perhaps she just got there early to beat the crowds.

All the appropriate gear is present: hat, gloves, coat – and her own skates.

Here’s a clue if you’re struggling.

Have a close look at all the pieces of kit listed above – and see if you can spot anything unusual about them.

Don’t worry if you’re still struggling, we’ve included the solution below.
