Third Party "Jackpot System" with Photon Unity Networking

Hi !

I'm developing a 2D game with PUN and wanted to add a "Jackpot System" to the game but don't have any idea on how to apply it on the game. I get the jackpot value from the database using WWW Request. When players lost the game, the jackpot will increase by 1000 for example. Players in a room can get the value sync but not players in another room or players in lobby.
Hope someone can help here.

Thanks
