It will take maximum concentration: a challenging chess puzzle game
Optical illusions and visual puzzles don't just make us strain all the forces of our brain, they actually train it a little bit. Cognitive health experts advise solving such puzzles every day and choosing the most diverse types of them to pump up your mental abilities.
For those who want to do this, OBOZ.UA publishes a challenging puzzle with chess pieces. Among seven dozen identical horses, you need to find one that is slightly different. And do it in 8 seconds.
That's how long it takes really experienced puzzle enthusiasts to find the answer to this puzzle. So try to test yourself by setting the timer for the specified period of time. But remember - you are not on an exam, so you can continue to search for the answer as long as you need. The main thing here is to cope with the task on your own, without any help.
Try to look at the whole picture first. If the answer doesn't catch your eye, start scanning each figure separately. Due to the large number of them, your eyes will wander from one to another, but try to maintain maximum concentration.
If even this approach doesn't work, then use the hint below. The chess knight you need is circled on it.
