If you're waiting to bet a game at a certain line, the new 'PRO Line Move' alerts will be very helpful. This feature allows you to enter a specific line and be alerted when/if the number moves there.
To enable these alerts, head to the 'Scores and Odds' tab and scroll to the game you are looking to place a bet on once the line moves to a certain threshold. Then, tap the 'bell' icon in the bottom left under the game you have selected.
From there, click the 'Set PRO Line Move Alert' option at the bottom.
In the example above, the Detroit Pistons +2.5, but you want to know when they reach +3. Once you save the alert you will see a 'blue dot' on the 'bell' icon indicating a PRO Line Move Alert has been enabled for this game. To remove or edit a PRO Line Move Alert, click the 'bell' icon again.
Once the line reaches the number you're interested in, you'll get an alert that looks like the one pictured below. If the line never reaches the desired number, you won't be alerted.
