There's a new machine that just hit the Harrah's casinos (Chester, PA and Harrah's AC), that I like to play (haven't seen it anywhere else). I don't remember the name, but it's a 7's based counting machine. The twist is it pays out based on the total number of 7's that are on the payout line, as opposed to having 3 7's in a row. In addition to bars, the reels have a single 7, a double 7 and a triple 7 option. It also has a 7 that can double your payout.

How it works: if you get 3 single 7's in a row the payout is minimal (your coin back). However, if you get 3 triple 7's in a row (9 Sevens), that's a big payout. If you get 1 triple seven and 2 doublers in a row, you have 12 7's (4x3).

It's a pretty unique concept.
