Playing at online casinos that accept US players means that you are able to register a real money account with the casino and play for real money as well. Players will attempt to play at casinos online that are not US friendly and as a result will not be able to register a real money account.
The options for players who reside in the USA are rather limited because there are few companies that develop software for the US online casino market and of those most are not willing to accept or take on the legal liabilities and implications of allowing their operators to accept players from the US. The only software providers that have operators accepting players from the US are listed here.
