This visual puzzle helps to exercise eyesight and brain. But the advantages are many more. Solve the problem and discover the benefits of this game.

In this riddle, you must find the number 53, hidden in this grid of 55. Using an intensely yellow board, comprising eighteen columns and fourteen rows, is not the only way to make finding number 53 among many 55.

The numbers are black and densely arranged on the board, and 53 looks more like a 55 than if the puzzle creator had chosen, say, the number 57. Time matters too: the faster you are, the better East. To complete this challenge, prepare a stopwatch. To see the figures better, you can zoom in on the grid by clicking on it.

What can help find the solution? Turns out, it’s not just keen vision. Lateral thinking is also useful, that is, thinking that allows you to look at the problem from another angle and see new possibilities.

If, despite looking carefully at the image, you have not been able to find the number 53, here is the correct answer. The number sought is placed in the eleventh column, on the penultimate line. Examining many columns one after the other can take more than 12 seconds. What method did you use to find the number 53 among so many 55?

It is not only these days that we train our brains by solving different types of puzzles. Ancient scholars already recognized the benefits of such practices. The positive effects of solving puzzles are many, including: exercising critical thinking, improving memory, training various problem-solving skills, providing an opportunity to be creative, reducing stress (it’s fun interesting and engaging), increase productivity (turning away, even briefly, from a task we are doing for a long time provides rest) and improving mood (a good result brings satisfaction and, in the long run, builds confidence in itself).
