does sams give you credit for 4x multipliers
If you're asking about the machines with positive games like FPDW, yes, you get the multiplier on these. (At least I did at one time. It's been awhile since I have played there.)
Someone mentioned here recently that the FPDW machines now take $4 to earn one point, so you won't get many points even with a multiplier.
