Aztec Riches casino is one of the oldest online casinos out there, and without doubt one of the best. They use Microgaming software, Microgaming seems to be the software of choice used by the majority of online casinos, along with Playtech and Real Time Gaming. Microgaming software is also a favourite of many of the online casino goers, likely because of the large variety of games, most Microgaming casinos have over 100 games to choose from, as well as some of the highest progressive slots payouts. They always have the better bonuses around, currently they have a bonus scheme that allows you to collect up to $850 by making 3 seperate deposits. The 1st deposit gives you a 50% bonus of up to $50, the 2nd deposit gives you a 25% bonus of up to $200, and the 3rd deposit gives you a 20% bonus of up to $600. We recommend this place, they are a reputable brand, and the golden Aztec theme of the site gives you the impression that they are really full of riches.
