5 play multi strike-worth a look?

[jimbarrt]

OK, first let me say, I walk by the many variations of poker machines, only playing jacks or better, 1 joker, or double down stud. For some reason, I found the five play multistrike on this site to be fun. Harrahs AC had them, so I sat down, donated my twenty, and clicked on the nickel value of joker poker.
 
Within a few hands, the 4X pay line dealt me a three of a kind, and I pulled the other two!!! Collected $800 off my $20 investment, and am undecided whether I should try for a repeat, or steer clear, knowing an attempt could cost me.
 
Went to bed a winner, but Caesars AC wasn't as generous the next day.
