Satoshi Dice uses a 1.9% house edge and backers get 50% of the house wins or losses. This means a 0.95% Expected Value (EV) that is shared by the backers. Affiliate earnings, Leader Board rewards and other rewards are not paid by the backers, and there are no additional fees. Minimum amount to bet on the house is 0.001 and there is no upper limit.
