-## Using Random Seeds for Randomizing Logic
+## Using Random Numbers for Randomizing Logic
 
-Seeds work via hidden fields. Create a hidden field named `seed_N`, where `N` is replaced with the number of arms you wish to randomize. For example: `seed_2`, `seed_3`, `seed_4`, `seed_5`,..., `seed_100`.
+Each respondent is given a set of random numbers, known as a "seed". Seeds work via hidden fields. Create a hidden field named `seed_N`, where `N` is replaced with the number of arms you wish to randomize. For example: `seed_2`, `seed_3`, `seed_4`, `seed_5`,..., `seed_100`.
 
 This hidden field will have the assignment of each user, which will be an integer between 1 and N. For example, if you made a hidden field called `seed_3`, each user will have a value of that field equal to 1, 2, or 3.
 
 Now use the hidden field in your logic jumps. If, for example, you create a hidden field called `seed_3`, then create logic jumps such that:
 
 if `seed_3 == 1` do A, if `seed_3 == 2` do B, if `seed_3 == 3` do C.
 
+## Using Multiple Random Numbers
+
+Say you want to randomize twice in your survey, independently, what can you do? 
+
+You can create multiple seeds, with the same bucket size, by using the format `seed_N_V` where `N` is replaced with the number of arms, as before, but `V` is used to represent a different version. For example: `seed_3`, `seed_3_1`, and `seed_3_2` will ensure that you can have three distinct random arms, each of which is independent from the other.

 ## Testing Random Seeds
 
 Random seeds can be tested just like any other hidden field, using the following format (testing seed_2):
