Has anyone signed up for this William Hill sign-up promotion?: https://www.williamhill.us/signing-bonus I plan on being in Reno on 2/10 and depositing $500 to bet on college basketball. The promo says it takes up to 30 days to add an additional $50 bonus, although I'm assuming that bonus is in the form of a bet which much be wagered on a mobile device in Nevada. Fortunately, I will also be in Vegas for March Madness on 3/17, so if I'm interpreting the rules correctly, I can collect my $50 bonus at that time. It sounds like a freeroll opportunity unless I'm missing something. Deposit $500, find a -110/-110 binary prop bet, bet $250 on each side, and collect your $477 +$47.70 bonus in 30 days for a quick $25 profit.
