The Roman Numerals in Your Password Should Multiply to 35: Rule 9 Guide
In The Password Game, Rule 9 requires the Roman numerals in your password to multiply to exactly 35. The easiest solution is V × VII = 5 × 7 = 35, while another option is I × XXXV = 1 × 35 = 35. The tricky part is that other uppercase Roman numeral characters in your password can affect the calculation.
This guide explains what Rule 9 means, how to solve it, which Roman numeral combinations work, and what to check when later password rules change your Roman numeral calculation.
The easiest solutions are V and VII, because V represents 5 and VII represents 7:
5 × 7 = 35
Another convenient solution is XXXV and I:
35 × 1 = 35
In this tutorial, we will learn about the functioning of Rule 9, which numbers can be used as Roman numerals, how to solve the problem, and why certain passwords that seem to fit the criteria don’t work.
What Is The Password Game?
The Password Game is an online puzzle that was developed by Neal Agarwal. It’s not just about generating a secure password; the game keeps adding weird conditions that need to be fulfilled.
Initially, there are very simple requirements, but as you advance, things get more and more complex. You have to fulfill several conditions like having numbers, capital letters, symbols, a month, a sponsor, a CAPTCHA, and the Wordle answer among others.
Rule 9 introduces Roman numerals.
The rule states that:
The Roman numerals in your password should multiply to 35.
Rule 9 requires the Roman numeral values in your password to multiply to exactly 35. Because later rules can force additional characters into your password, you also need to check whether those characters affect the calculation.
What Does “The Roman Numerals in Your Password Should Multiply to 35” Mean?

If you are searching for the roman numerals in your password should multiply to 35, you are essentially looking for Roman numeral combinations whose numerical values have a product of 35.
The first step is to understand the basic Roman numeral values:
| Roman Numeral | Value |
|---|---|
| I | 1 |
| V | 5 |
| X | 10 |
| L | 50 |
| C | 100 |
| D | 500 |
| M | 1,000 |
These are the standard Roman numeral symbols.
Now look at the number 35.
“The useful factor pairs are:
1 × 35
5 × 7”
The useful factor pairs are:
- 1 × 35 = 35
- 5 × 7 = 35
This immediately gives us the two practical solutions for Rule 9.
The Two Main Solutions for Rule 9
There are two straightforward ways to make the Roman numerals in your password multiply to 35.
Solution 1: V × VII = 35
The first solution uses:
- V = 5
- VII = 7
Therefore:
5 × 7 = 35
This is a straightforward solution for Rule 9. VII represents seven because it combines V (5) with two I symbols (1 + 1).
So:
VII = 5 + 1 + 1 = 7
And:
V × VII = 5 × 7 = 35
This is why many guides recommend adding V and VII to your password.
For example, a password containing:
V...VII
can satisfy the multiplication requirement, assuming no other Roman numeral characters in the rest of the password change the calculation.

Solution 2: XXXV × I = 35
The second solution is often easier to manage.
XXXV = 35
And:
I = 1
Therefore:
XXXV × I = 35 × 1 = 35
This gives you another valid way to satisfy Rule 9.
Many players prefer XXXV because it represents 35 directly. You only need an additional I, whose value is 1, to preserve the product:
35 × 1 = 35
This approach can be especially useful when later rules make the V + VII combination inconvenient.
Why Are V and VII Used?
If you are wondering why V and VII are the popular answer, the reason is simple mathematics.
The target number is 35.
Its prime factorization is:
35 = 5 × 7
Roman numerals provide:
- V = 5
- VII = 7
So the Roman numeral representation of the factors gives us exactly what we need.
Step-by-step:
- Find the target number: 35
- Find its factors: 5 and 7
- Convert 5 to Roman numerals: V
- Convert 7 to Roman numerals: VII
- Multiply their values: 5 × 7
- Result: 35
Therefore, V and VII satisfy the requirement.
Why Is XXXV Sometimes Better?
Although V + VII is a straightforward solution, XXXV can be more convenient.
XXXV represents 35:
- X = 10
- X = 10
- X = 10
- V = 5
So:
X + X + X + V = 35
When treated as the Roman numeral XXXV, its value is 35.
If the password also contains I:
XXXV × I = 35 × 1 = 35
This is the reason guides frequently recommend XXXV as an alternative.
However, there is an important consideration: The Password Game becomes increasingly complicated as you progress. Other rules may introduce letters that are also Roman numeral symbols. Consequently, changing your password later can accidentally alter the Roman numeral calculation.
How to Solve Rule 9 Step by Step
If you are stuck on the roman numeral in your password should multiply to 35, follow these steps.
Step 1: Identify Roman Numeral Letters
The standard Roman numeral symbols are:
- I
- V
- X
- L
- C
- D
- M
Pay attention to capitalization because The Password Game uses Roman numeral characters in the password rules. Guides for Rule 9 specifically note that uppercase Roman numeral characters can affect the calculation.
Step 2: Find the Factors of 35
The number 35 can be divided into:
1 × 35
and
5 × 7
There are no other positive factor pairs that produce 35.
Step 3: Convert the Factors Into Roman Numerals
Five is:
V
Seven is:
VII
Thirty-five is:
XXXV
One is:
I
Therefore, the two useful combinations are:
V × VII = 35
or:
XXXV × I = 35
Step 4: Choose Your Preferred Combination
If you want the traditional factor-pair solution, use:
V and VII
If you want to use 35 directly, use:
XXXV and I
The second option is often described as the easier alternative because XXXV already represents the target number.
Step 5: Check the Rest of Your Password
This is among the most critical steps.
Do not assume that only the Roman numerals that you inputted deliberately will make a difference.
In case your password has other uppercase I, V, X, L, C, D, or M, they may affect your calculations.
For instance, consider a case where you have intended to input:
V + VII
but another rule forces an uppercase C into the password.
C represents 100.
Now the calculation may no longer be:
5 × 7 = 35
Instead, the additional Roman numeral can make the product dramatically larger.
This is why solving Rule 9 is sometimes easy initially but becomes difficult later in The Password Game. Players have reported situations where later rules introduce Roman numeral characters that disrupt an otherwise valid solution.
What Roman Numerals Are Used in The Password Game?
Understanding the seven basic Roman numeral symbols will make Rule 9 much easier.
I = 1
I is the smallest standard Roman numeral and represents one.
It is useful in Rule 9 because multiplying by one does not change a number:
35 × 1 = 35
That makes I + XXXV a useful combination.
V = 5
V represents five.
It is one half of the classic Rule 9 solution:
V × VII = 35
X = 10
X represents ten.
Be careful with X because even one additional X can change your calculation.
L = 50
L represents fifty.
A capital L represents 50, so an unintended L can make it much harder to satisfy a product-of-35 requirement.
C = 100
C represents one hundred.
This is another dangerous character for Rule 9 because 100 is already greater than the target number.
D = 500
D represents five hundred.
A capital D can similarly cause problems.
M = 1,000
M represents one thousand.
An unexpected M can make the Rule 9 requirement impossible unless the game’s interpretation and other password elements provide a way to avoid it.
The standard values of these symbols are confirmed in Rule 9 guides.
VxVII vs. IxXXXV: Which Should You Use?
You may have seen solutions written as VxVII or IxXXXV.
You may also encounter solutions written as VxVII or IxXXXV. In these examples, the uppercase Roman numeral characters are the ones relevant to the Roman-numeral calculation, while the lowercase x is shown as a separator.
For example:
VxVII
can be understood as:
- V = 5
- x = ordinary lowercase character
- VII = 7
The relevant Roman numeral values are therefore:
5 × 7 = 35
Similarly:
IxXXXV
can separate:
- I = 1
- XXXV = 35
Giving:
1 × 35 = 35
The key point is that the Roman numeral groups must produce a product of exactly 35.
Common Mistakes When Solving Rule 9
Many players make the same mistakes when attempting this challenge.
Mistake 1: Adding Instead of Multiplying
The rule says the numerals must multiply to 35.
You should not calculate:
V + VII = 12
Instead, calculate:
V × VII = 5 × 7 = 35
This distinction is critical.
Mistake 2: Using the Wrong Roman Numeral for Seven
Seven is:
VII
It is not simply V.
V is 5.
VII is 7.
Therefore:
V × VII = 5 × 7 = 35
Mistake 3: Using XV and VII
XV represents 15.
VII represents 7.
Therefore:
15 × 7 = 105
That does not satisfy Rule 9.
The target is exactly 35.
Mistake 4: Adding Extra Roman Numerals
Suppose you have already created a working combination:
V × VII = 35
Then you add another capital X.
Now you have an additional Roman numeral with a value of 10, which can change the calculation.
This is one of the biggest reasons a solution that worked earlier can stop working later.
Mistake 5: Forgetting That Later Rules Can Change Your Password
The Password Game does not stop at Rule 9.
Later requirements can force you to add new characters, words, symbols, or other content. Some of those additions may contain Roman numeral characters.
Community discussions show that players frequently encounter this problem when later rules introduce additional uppercase Roman numeral letters.
Therefore, after changing your password, always re-check Rule 9.
The Best Answer for “The Roman Numerals in Your Password Should Multiply to 35”
If you want the simplest answer, remember:
Option 1
V × VII = 5 × 7 = 35
Option 2
XXXV × I = 35 × 1 = 35
Both approaches can satisfy Rule 9 when the rest of the password does not introduce additional Roman numeral values that alter the product.
For many players, XXXV and I is an attractive option because 35 is represented directly by XXXV.
Why 35 Is Easy to Solve Mathematically
The reason this puzzle is manageable is that 35 has a very simple factor structure.
Its prime factors are:
35 = 5 × 7
Because both 5 and 7 are prime numbers, there are only two positive factor pairs:
- 1 and 35
- 5 and 7
Roman numerals make these:
- I and XXXV
- V and VII
This is why Rule 9 has such a limited number of useful solutions.
It is not necessary to try dozens of combinations. You can solve it directly using factorization.
Quick Cheat Sheet for Password Game Rule 9
If you want a quick reference while playing, use this table:
| Roman Numerals | Values | Product | Works? |
| V × VII | 5 × 7 | 35 | Yes |
| I × XXXV | 1 × 35 | 35 | Yes |
| V × V | 5 × 5 | 25 | No |
| X × VII | 10 × 7 | 70 | No |
| XV × VII | 15 × 7 | 105 | No |
| X × XXXV | 10 × 35 | 350 | No |
| I × XXXV × V | 1 × 35 × 5 | 175 | No |
The goal is always:
Product = 35
Not 34, not 36, and not 350.
These searches all point toward the same fundamental concept: finding Roman numeral values whose product equals 35.
Frequently Asked Questions
What is the answer to Rule 9 in The Password Game?
The simplest answers are V and VII, because:
5 × 7 = 35
Another valid approach is XXXV and I, because:
35 × 1 = 35.
What Roman numerals multiply to 35?
The practical Roman numeral combinations are:
V × VII = 35
and:
I × XXXV = 35
These correspond to the factor pairs 5 × 7 and 1 × 35.
Is XXXV a valid answer for Rule 9?
Yes, but remember that XXXV represents 35. To make a multiplication expression equal 35, it can be paired with I:
XXXV × I = 35 × 1 = 35
This is why XXXV is commonly recommended as an alternative solution.
Does VVII mean 35?
No.
This is an important distinction.
VII represents 7, while V represents 5. The intended mathematical relationship is:
V × VII = 5 × 7 = 35
Do not treat VVII as a standard Roman numeral representation of 35.
Can I use lowercase roman numerals?
For The Password Game, capitalization matters when satisfying the Roman numeral rules. Guides specifically identify the uppercase Roman numeral symbols as relevant to Rule 9.
Therefore, when trying to satisfy the rule, use the appropriate uppercase Roman numeral characters.
Why does my correct answer stop working?
The most likely reason is that another part of your password contains an additional Roman numeral.
Remember these symbols:
I, V, X, L, C, D, M
If another rule requires you to add one of these as an uppercase character, it may change the multiplication result.
Check your entire password rather than looking only at the Roman numerals you intentionally added.
Is V × VII the only solution?
No. There is also the 1 × 35 factor pair:
I × XXXV = 35
So the two main solutions are:
V × VII
and
I × XXXV
Both produce 35.
Why does The Password Game make this rule difficult?
The math is easy enough. What is hard is the need to meet all the requirements at once.
A good solution according to Rule 9 may no longer work once you are forced to add a character according to Rule N which is a Roman numeral.
It is because of this that successful gameplay requires you to understand the relation between the rules rather than deal with them individually.
Final Tips for Passing Rule 9
- Remember that the target is 35.
- Think in terms of multiplication, not addition.
- Use V × VII = 35 or I × XXXV = 35.
- Check the entire password for uppercase Roman numeral characters.
- Re-check Rule 9 whenever you modify your password.
Conclusion
The Roman numerals in your password should multiply to 35 is Rule 9 in The Password Game. The easiest way to solve it is to factor 35 into 5 × 7, which gives the Roman numeral combination V × VII = 35. Another option is I × XXXV = 35.
The main challenge is keeping the calculation correct as you progress through the game. When later rules require you to add new characters, check whether any uppercase Roman numeral symbols have been introduced. With the correct combination and a careful check of the rest of your password, Rule 9 becomes much easier to manage.
