We suggest the following exercise: look around and name as many things as possible that are in the same room with you and begin with the same letter, including mental concepts. Therefore, first of all, it is worth “pumping” such observation, over the surrounding phenomena and things more often. This is what makes it possible to synthesize something new. Games for home entertainmentĪt one time, Steve Jobs, the man synonymous with the word "creativity", emphasized that people who have the skill of creative thinking do not invent, but rather notice the connection between several things. Tip: number the dots right on the paper, so it will be easier to figure out the solution. To solve this and similar puzzles, it is worth developing and discovering unusual approaches to the problem. "Advanced" individuals can solve it even without the help of glue, the main thing is to imagine the end result. When you return the leaf to its original form, you will see that three lines have been drawn on it, covering all the points, which fits into the conditions of the puzzle. Connect the place under 7 and 8 with a dot to the place under 2 and 3.ĭraw one solid line starting at point #1 and spiraling down. A tube of decorative cosmetics (lipstick or foundation) is ideal. Draw nine circles on a square sheet (sticker) (as in the problem). There is also a "hardcore" method for those who know spatial thinking. It turns out a kind of arrow-cursor that can be directed to any of the four corners as you wish. We turn through the corner of the square, passing the rest of the way through the points numbered 1.5 and 9.Without taking your hand off the sheet, we make a corner and strive for the point numbered 8 and 6 and go beyond the framework in the same way.We draw the first line, starting from point 1 through 4, 7 and go beyond the boundaries of the figure.Let's conditionally number each point from 1 to 9: We analyze the task based on knowledge about the object, but we should just remember that a straight line is not necessarily limited by the form, that is, it is possible and necessary to go beyond the boundaries. Here you need to go beyond logic and stop thinking in terms of the four sides of the square and its diagonals. First of all, logical thinking developed, on the principles of which our world is built. The thing is that from childhood we were taught to think, starting from certain patterns and rules. At first glance, it is not so difficult, but in fact, each subsequent attempt often moves the inquisitive mind away from a positive result. The next line should start where the previous one ended. The following conditions must be met: cross all nine points that form a square using straight lines (no more than four).Ī hand, or rather, a pencil, in this case, cannot be torn off the sheet. This mystery has intrigued hundreds of thousands of people.
#Connect dots with 4 lines how to
The clue without further ado: how to connect nine dots using four lines? M We are sure: desire and work, self-education and the experience gained will help you reach a new, non-trivial level of thinking. Rather, the solution itself, like most similar tasks, is not based on logic, but rather on creativity. Xinding Sun from University of California, Santa Barbara found yet another twist to the problem.įurther variants are discussed at the CTK Exchange - the old archive.Let's face it, this is a trick question. Thought and points out even more of self-imposed restrictions that I missed considering the 9-point problem Now, try to think of a restriction you imposed on yourself which was not inherent to the problem.Īs an aside, Lars Hellvig from Stockholm, Sweden picks up this line of The solution lies in the observation that it's permissible to cross square boundaries. For one always comes up with 5 lines instead of 4. The problem is to connect the dots with no more than 4 straight lines without lifting your hand from the paper. One classical example is where nine dots are arranged on the sides and the center of a square as in the picture below. The best hint, in my view, is to mention that often, when solving a problem, we implicitly impose constraints that have not come with the problem.
