I also had something in my inbox for 25 free spins on another game, which I did and won some coins there. I ran out of coins before hitting a jackpot, and had to go searching the internet for free coins to load up again, but there were plenty of sites available for this. I stayed on Bank of Jackpots with bidding 100 (minimum bid).
I just did this one yesterday too, and had a similar experience.
