The object of the game is hiring more piggies, sooner and more often than other players. This in turn earns you more USDT faster. Hiring more piggies using your daily USDT earnings (compounding) will 3x your piggies within 30 days or less.
First, you buy piggies by depositing USDT. Once you've bought piggies, those piggies immediately start producing 5% average daily rewards for you and will continue producing rewards forever, as long as there is a balance in the contract. Your earned USDT rewards can be used to hire more piggies (compounding) or withdrawn directly to your wallet anytime.
