I watched before depositing. Across their approximately 10 sites ('sister', for whatever that means) there is only ONE winner.
You're not playing against 50 people - more like 500, with one winner. And the same names win; constantly, regularly, regardless. The odds of that happening are astronomical (to say the least). Excusing this irregularity as 'luck' is disingenuous and quite frankly, insulting - luck doesn't figure in statistical mathematics.
(enter at least one hundred words? you're kidding, right?
the flaws can be pointed out in less than fifty - I'm writing this purely to entertain your guidelines - 100 mandated words). (ahdycb fhfhcnbn chhfbd nfguyrf cjdhfsj ehfdbc bdbcsbnb vjfhb hfbcdb hfjd vjvjdjv jhgfmdc sfhiv fbkvkfnv there, enough?)
Reason of review: Bad quality.
