That is what Dragon fights were newfag. They were insanely popular on 4cuck /b/.
The premise was simple:
A thread on /b/ was created to link anons to a website with a minigame that tallied/tracked the dragons HP, the thread, and damage history of anons posting the dragon fight thread. The website was given the address of the active thread on /b/ dedicated to the fight.
The website would track the user IDs to assign the anon a fighter class such as fighter, mage, ranger, healer, and dragon knight or some rare cool classes like Dovahkiin (for posters who got 00 digits in the thread ID)
It would track the thread post digits for damage, or healing/reviving other anons.
So when you post on the thread in /b/ the fight basically progresses as users shitpost.
And only one thread would be tracked by the site. Also it would be tradition or courtesy to post an OP pic of a dragon or some funny image to flag users of the dragon attacking /b/.
