The best way if you're new to the game is to seek out the betting information table near the betting windows, they will be happy to give you a good explanation and instructions. Go in between races, right after a race is over. The closer to a race the busier they are. Good luck.
The best bet is to get a card. When you go to saratoga, look for the look for the NYRA Bets booths. Out in the back yard I saw a both. When you sign up for NYRA Bets, you can place bets on your phone or using your card at the betting machines located throughout the property
