facebook games working slowly on surface pro 3 and macbook pro. flash issue?

I bought a surface pro 3 thinking it would run facebook games easy since its stats are higher than the laptop I currently use and to run the ones that have both formats as apps.

I found out not only does it not fit well on the screen but it runs really slowly and was surprisingly dissapointing. Add to that the games that have app format aswell like castleville weren't available on windows and hardly anything was and I have been sorely dissapointed. 

I tried my husbands macbook pro thinking that maybe that would be a better portable solution with its elegant light design. I mean that still would not have the games from google apps but surely that would be able to run it in the native facebook and then I would just use my phone for apps or get a cheaper google tablet down the track and keep the purpose of the tablet and laptop separate.

While it ran better on the macbook pro it still did not run as fast or as smoothly as the older toshiba windows 10 laptop. It also made the poor macbook work hard enough to have the fans going at full steam inside the macbook pro.

Now I am completely stumped. With the stats of the macbook pro, how on earth is it having to work so hard to run my facebook games? What is it I should get that would be able to run my games in a portable format to go from room to room or to stay with my parents. Any advice?  I have had it suggested to me that it may be adobe flash player.  I have the latest adobe flash 11 installed on each one.  Do you have any suggestions on how to get it to work better on the latest macbook pro than on the regular laptop?
