First of all, there are 2 different kinds of notifications:
First one is fully customizable and you can get mobile app alerts on them. To start creating them, open the left side menu and click on Create notification. You can pre game odds and lines movements, inplay odds and lines movements, inplay stats, game time, momentum and many more different things.
The second one is in-play notification. You can activate it when clicking on the bell icon after the game. Main purpose is getting alert when theres inplay line and odds available you were waiting for. For example: Current total goals line is 3.5 and you dont want to bet anything over 2.5 goal line. You can quickly create alert so the tool notifys you when and if the 2.5 goal line is available with the minimum odds you prefer.
