When viewing a race card you will see a yellow Create Bet button in the upper right corner when you are logged in. Click here to create a wager.
This will open a Bet Ticket. You can select the Track, Race Number, Bet Type, and Bet Amount using the drop down menus at the top of the Bet Ticket. Click the squares to the left of the horses names to select your horses, then the green "Confirm Bet" button to create your wager.
The "Confirm Bet" button will show as a pale green and read "Please make your selection" if you have not created a valid wager.
You will then be asked to confirm you wager. You can turn off future confirmation message by checking the box toward the bottom of the ticket. (This setting can also be found by clicking "Account" at the top of the page, then "Edit.") Click "Submit Bet Now" to confirm the wager.
You will then get a confirmation message when your wager is placed.
