根据一系列数字在Symfony2中定义路由要求

I'm playing around with a symfony tutorial and I was wondering if and how I can use different routing based on the amount of a given wildcard in the URL-path. Here is the code of my routing yaml:

app:
resource: '@AppBundle/Controller/'
type: annotation

luckynumberSmallNumbers:
    path:      /lucky/number/{max}
    defaults:  { _controller: AppBundle:Lucky:smallNumber, max: 10}
    requirements:
       max: \d+ #TODO: something to define numbers smaller  or equal to 10

luckynumberBigNumbers:
    path:      /lucky/number/{max}
    defaults:  { _controller: AppBundle:Lucky:bigNumber, max: 10}
    requirements:
        max: \d+ #TODO: something to define numbers greater than 10

So e.g. in my example the path would be /lucky/number/{max} If the number given in {max} is greater than 10, another method/controller should be called than if the number is below or equal to 10. How can I define this in the requirements for 10? I only found reqular expressions and I do not know how to bend those to my will :) Find my repo here: https://github.com/mattlang88/first_symfony_project

Thanks a bunch!

    requirements are regular expressions (regex), so you can have a regular expression like ^([0-9]|10)$

    for the second one you can define a regex for numbers bigger than 10 like this: ^0*([1-9]\d{2,}|0*[1-9]\d)$
