How is Nine Links done, and how to play Nine Links Step by stepWhat are the steps?

The nine rings sold on the market are generally produced by iron factories or toy companies, and there are special processing tools for production. No molds are required.

It can be made by hand, but generally does not use hard wires. Use pliers and hammers to make rings, or you can buy some key rings instead.

I tried it, and I vomited it directly, and I was advised not to play, and not to embarrass yourself.

1. Loosen the first and third rings, and in the initial state, all rings are set on the bracket.

2. Pick up the first ring from the left side and lower it from the top so that the first ring is easy to unlock and the third ring can be unlocked in the same way. Untie the second ring and put on the first one. Putting on clothes is the opposite of dismantling.

3. After installing the first ring, you can untie the first ring and the second ring at the same time, so that the first three rings can be untied.

4. Use the first step to unlock the fifth ring. Since the fourth ring is on top, you can get the fifth ring directly.

5. Untying the fourth ring is the same as unlocking the second ring. To put on the third ring, put it on in the opposite way than to disassemble it.

6. After installing the third ring, the fourth ring can be untied, while the third ring is still on it.

7. Use steps 1 and 2 to unlock the third ring in order to unlock the first five rings.

8. Use step 1 to unlock the seventh ring. Since the sixth lap is on top, you can wear the seventh lap directly.

9. Install the fifth ring. The installation method is the opposite of disassembly. Once the fifth ring is installed, the sixth ring can be unraveled.

10. Use the first step to unlock the ninth ring. Since the eighth ring is on top, you can wear the ninth ring directly.

11. Install the seventh ring. The installation method is the opposite of disassembly. Once the seventh ring is installed, the eighth ring is untied, and the seventh ring can be untied at the same time.

The nine-link tutorial step by step** is as follows:

1. The initial state of the Nine Rings:

2. Lift the first ring off the rod and lower it from the middle:

3. According to the method of winning the first ring, you can win the third ring:

4. After installing the first ring, dismantle the side and imitate the first one at the same time. The second ring. At this time, the first three rings were all won:

5. Take off the fifth ring according to the method of taking the third ring:

<>7. Install the fourth ring, and the first four rings are on the rod:

8. Start from the front and remove the first four rings:

9. And so on, take off the first seven rings:

10. The appearance of all rings removed:

Dismantling principle:

1. It takes a total of 256 steps to unlock the nine rings, as long as the upper or next ring, even if it is one step, each ring of the nine rings restricts each other, and only the first ring can go up and down freely. In order to play the nth ring, two conditions must be met (except for the first ring).

2. The n-1st ring is on the rack; The rings in front of the n-1 ring are not on the rack at all. Playing Nine Links is all about trying to meet the above two conditions. Untying the nine rings is essentially to start from the back rings, and the first ring in front is to lower the back ring, and the front ring has to be installed, which is not really taken off.

3. Let's start with the simplest one. It takes 1 step to solve a chain: one step. It takes 1 step to dismember the two chains: one, two. What about the unraveling of the triple link? It takes 4 steps: one, three, one, one, two.

5. That is, to solve a chain, then untie the last ring, and then solve a second link. It takes 7 steps to solve a four-in-a-row: one, two, four, one, two, one, three, one, one, one, two.

That is, to solve a two-link, then to solve the last one, and then to solve a two-link, and then to solve a three-link.

6. In other words, to solve the N-chain, is to solve an N-2 chain first, then the last ring, then the N-2 chain, and then the N-1 chain.

7. It takes 1 step to solve a chain and 1 step to solve a chain. It can be seen that it takes 4 steps to solve the triple chain, 7 steps to solve the quadruple chain, 16 steps to solve the fifth chain, 31 steps to solve the sixth chain, 64 steps to solve the seventh chain, 127 steps to solve the eighth chain, 256 steps to solve the ninth chain, and 682 steps to solve the tenth chain......Later analogy.

Nine rings are traditional Chinese folk intellectual toys, made of wire 9 rings, the rings are set on horizontal plates or various frames, and the ring handle is through. When playing, follow a certain procedure and repeat the operation, so that the 9 rings can be untied separately or combined into one.
