Aqua Online's casino software is called Cytech. In many ways it is similar to Microgaming software; the selection of games, game rules, method of payment, and even account numbers resemble those of Microgaming. Both real and fun modes are available, although a separate account is required for each. Methods of payment include credit card, PayPal, and ClearChex. The game play is fast, clear, and user friendly. Withdrawal fees can vary by casino.
