How do I collect my win

Did you read the Terms & Conditions ( https://www.bigwinboard.com/tournaments-guide/ )?

Starting with the "How to Join"

you just need to be an active member with a history of engaging in forum discussion or posting feedback in the review articles

And your 3 first posts were basically spam, made in the last 5 minutes.

Probably there will be a need to verify if this isn't just a throwaway account from someone that just created a bunch of accounts to abuse the tournaments in the first place.

@itaghai this is my only account bro, idk how to even claim the reward or anything and no chance im spinning 2500 spins multiple times took me like 2 hours to finish spinning 🤣

You can't unless you have earned 3 forum points... WTF? 

@thecasinosamurai wdym!?!?! I think you mean 3 posts not points.

Jika sudah menang bagaimana saya mengklaim hadiah?
