Actually ... Google results are: 7,210 with the search request as "CASINO BOAT" (in quotes). This is important for accurate results.
It's also a "search" or "type in" (generic) type of domain ... residing in the less favorable ".NET". Finally, it's not plural, as well.
Now ... that is not all, as there appear to be some End uder type potential leads on Google, as well: http://www.casinoclassifieds.com ... that may have a use for it.
Is the ".COM" owned, or better ... developed? How about the pluralized ".NET". Possibly other leads here, as well, IMHO.
$15 - $28.75+ at the wholesale/reseller level, IMHO.
Best of Luck here.
