How to beat Rule 18 of the Password Game – Atomic numbers that add to 200

The Password Game by Neal.Fun requires concentration—especially when it comes to Rule 18. Solving Rule 18 requires strategically finding atomic numbers that add up to 200. So, we’re here to tell you what an atomic number is and how to add them to get a specific number.

Here’s how to beat Rule 18 of The Password Game and more about atomic numbers.

How to beat Rule 18 of The Password Game

To satisfy Rule 18 for The Password Game, you have to choose elements from the periodic table and have their atomic numbers add together to equal 200.

Each element on the periodic table has an atomic number, and you likely already have a few in your password—some intentionally, some by accident.

In my puzzle above, the elements V, Zn, and N were highlighted—but the only atomic element I entered was Zn to satisfy Rule 12. You may find this also happens to you, whether it be due to needing a Roman numeral or because of a random element appearing in your captcha.

Fortunately, depending on how many atomic elements you’ve included, you may be one character away from resolving Rule 18. Here are some steps to follow once you have simplified your password:

1. Figure out and note down the numbers that should stay. These are your constant values that equal the total Atomic number. Check the table below for more Atomic values.
2. Add those constant values together to determine your Atomic total.
3. Subtract that Atomic total from 200.
4. Then add in the Atomic number(s) to get from the sum of the Atomic total to 200.
5. This will then satisfy the rule.

Below, we’ve included a table listing each element’s atomic number. If you find you are over the limit, keep in mind that most of the rules aren’t case-sensitive, whereas atomic elements are. Simply dropping an element to lowercase will remove it from the overall count to 200, which may free you up to add another symbol.
