Risco Total is essentially Diamant/Incan Gold, with the exception that it was a non-authorized production of the game. According to game designer Bruno Faidutti, Grow Jogos e Brinquedos did not have license to produce this game, thus it was set apart from the official entries of Diamant/Incan Gold.
An agreement has since been made between the authors and the publisher. Then, the licensed version was renamed to Tensão Total, without any other changes except authors credits.
All players play with a group of divers looking for treasures in deep sea.
Every round a player need to decide if he will dive more or will go back to the surface. A card is turned, if it is a treasure the players who stay diving will take the gold coins, but if you find a shark... look out, your oxygen can finish or you can find other threats in the deep sea.
The diver with the most successfully retrieved money wins the game.
