#### What is Smart-Difficulty
Smart Difficulty Scaling is an advanced security feature of Friendly Captcha.

Every second, a large amount of requests is processed through our systems. Smart Difficulty Scaling uses advanced algorithms based on additional signals to dynamically scale the difficulty of the cryptographic puzzles played out. 

As a result, suspicious requesters have to spend more processor resources to solve the puzzles and the security level is increased.


#### How to activate Smart-Difficulty 
First of all you need an account which is subscribed to an Advanced or Enterprise Plan.

Once you have created an application, you can enable the Smart Difficulty Scaling option in the application settings.
