All of this is to be done at the casino cashier. To claim them, simply copy their bonus code (if there is one) and make the minimum deposit required. Once you’ve done all of that, you can start picking the bonus codes you deem fair and worthy of your money.
Knowing the minimum deposits bonus codes require, their max cash-out limits, or the wagering requirements they have will make it easy to filter out the good from the bad/unfair bonus codes. They are long, and boring to read, but necessary. After creating your new player account, there is one last step you must do before claiming your first new player bonus - read the bonus terms and conditions.
