How do i receive a 20% cash bonus(up to 20$) on my first deposit?

First, register a new account by creating your own personal username and password.
Then, in the Game Lobby, click on the "Cashier" button. After the Cashier page loads, click on the "Deposit" button. You will be prompted to fill a registration form and afterward you will be ready to make your first deposit.
Select your preferred payment method and enter your payment details. Make sure you enter POOL20 in the "Bonus Code" field when making the deposit. If you do not enter the bonus code, you would not receive the bonus! You may now click the "Submit" button and have your payment processed.

After you play 30 games, the bonus will be released from your bonus account to your playing balance. You can track your progress in the Cashier by clicking on the "My Bonus Account" button.
