Hello,
The main benefits of playing games like Knockout Trivia are possibility to obtain great number of TCredits.
Some of them are free, and some of them require 1TC for playing.
For many affiliates buying Tcredits is expensive, so this is a good way to earn them by using your knowledge.
There is also a matter of some luck, but they should be persistent.
I hope that this will help.
Best Regards
