In the past, bettors had to manually look up the odds for every bet on every game in order to find the most advantageous odds. Sidelines simply automated the process by pulling all the data directly from the sportsbooks to display the odds with the best value for every bet on every game.
As we mentioned, sportsbooks are not in the sports betting business out of the good of their hearts, but rather, their wallets. Given that sportsbooks set and adjust odds more as a way to minimize their risk (thus not leaving themselves exposed to serious losses), it is only natural that all sportsbooks do not give the same odds for the exact same bet! This presents an opportunity for savvy bettors to ensure they get the best value on their bets and maximize their payouts.
