# Does the chance of catching a Pokémon change with each throw?

• In GamePress's article about Catch Mechanics, they describe how the capture chance is calculated for each ball thrown. At the end of the article they say this...

### Catch Success and Failure

Finally, the server generates a Random Number between 0% and 100.0%. If Final Capture Chance is greater than this random number, the Pokémon is caught. If Final Capture Rate is less than this random number, the Pokémon breaks out and possibly flees.

How the capture rate is calculated is explained well in article, however, what I don't understand is when the Random Number is chosen. Is a value chosen with each throw, each encounter, each spawn?

So basically, I can modify the Final Capture Chance by giving a Razz Berry, throwing a different type of ball, and/or throwing the ball when the target circle is smaller/larger. But if the Random Number is 100%, and it never changes for that Pokémon. Then I don't have much chance of ever catching the Pokémon. However, if the Random Number changes with every throw, then I always have a chance to catch it with the next ball (assuming it doesn't run away).

• Based on the quote you provided, where it says:

If Final Capture Rate is less than this random number, the Pokemon breaks out and possibly flees.

This indicates that this random number must be generated for each throw.

Many times now, I have attempted to capture Pokemon with Pokeballs, getting Great or Excellent throws, then failing, but then throwing a Pokeball with no accuracy bonus, and catching the Pokemon. If the random number did not change with each throw, these cases would be impossible.
