As you progress in The Password Game, new rules will be thrown your way, continuously making the experience more complicated. The problem is the current rule you are working on can always interfere with previous ones you have done. With that in mind, Rule 18 can be tough for anyone not in high school currently. It says, “The elements in your password must have atomic numbers that add up to 200.” Not only do you need to keep math in mind, but now science is being incorporated. Here is how to do it.
How to do Rule 18 in The Password Game

The only things that are really important to get this rule done is the abbreviations and their atomic number. You will need to do a little math to get them to add up to 200, but be sure to account for other symbols already in your password.
For example, in Rule 9, we used V and VII. This will account for two uses of Vanadium, which has an atomic number of 23, and two uses of Iodine, sitting at 53. That alone puts us at 152. In our chess rule, we had to put Rh, Rhodium, adding another 45 for 197 total. With our first word being Hello, He makes Helium, adding two more for 199. All we had to do was add an H at the end for that last push.
Keep in mind that your future additions to the password will also affect your ability to get atomic numbers that add up to 200. Keep the table above handy so you can swap out some periodic table elements when needed.
