While it does seem strange that a few of the players who won were people who don't play very often, it can happen.
To be honest here.....
I remember an instance last year where I read an american have won the lottery jackpot twice.
Many people buy a UK national lottery ticket for the 1st time and win £5 million+
There's millions of people who have bought tickets every week for the past 10 years and never won anything at all.
Difference with the UK Lottery though is that the numbers are drawn live on TV for the country to see.
Transparency is the key to this issue.
I'm far from advising WGT how to run their successful business and to be honest Chad looks like he has an honest face plus TarHeelsRule has stated he's won a few randoms and he seems a genuine guy.
Not sure what WGT could do to make things more transparent. Maybe do a live web cam session with Icon dressed in a TuTu pressing the trigger then out pops a random winner.
Edge has raised a valid topic IMHO......because these random sweeps prizes can have a value of $5K +
