I like playing the penny denomination of WMS Gamings, "All The Glitters" and "Kaboom". You can affordably play all 20 lines, and maybe a few coins per line. With a little luck, you can pick up $100 here and there ... and a $20 will last 30 to 60 minutes on an average play.

I don't know about playing a "single penny" -- because winning $1.00 or $2.00sounds like a waste of time. Yes ... I like to play for a while ... but there needs to be the exciting of having some decent up-side potential.
