Aztec Returns is exactly like Shisen-sho games, but with spectacular graphics based on the ancient Aztec culture. In many places, it is also called "four rivers". The game is based on Japanese tiles, similar to Mahjong tokens, only this time the tokens have been replaced by spectacular Aztec hieroglyphics tiles. The goal is to eliminate identical pairs of tokens, until every board is empty, like Mahjong games.
The main feature of this game is that it is a game to train the brain. It is very simple to play, and can provide hours of fun. Also has a very elaborate graphics, very nice effects and music or ambient sound very relaxing.
