You can vote once per category. So, if an operator has a casino and a sportsbook, you can vote once for best online casino and once for best bookmaker award. If you wish to vote for the best online casino, then take your time to get a feel for a number of the best online casinos for U.S. players. This will allow you to make the right call and vote for the best casino in your opinion. Although you can only vote once per award, you’ll be able to vote for all categories. Plus, you can always change your vote in the future if you happen to find a better online casino.
