Swagbucks, Swagbucks Live and Playtime Rewards.

Hello, sorry if this has been asked before, I can't see where it has. I like playing the games and was wondering if we can play a game only once between Swagbucks, Swagbucks Live and Playtime Rewards or if they are considered different platforms so we can get credit playing on each one?

Also does anybody have any suggestions of apps that has a lot of games to play to make money? I also do My Points and Inbox Dollars and was wondering if there are any others good for games. Thanks!
