I had a chance to play IGT's "Rapid Riches" progressive. There was a bank of four machines connected to a 2-cent progressive which had 4 levels of jackpot. The top amount available was in the $10K range.
If you play 20 credits, you play the bars and WILDS. If you play 60 credits, it adds in other symbols (such as blazing 7's). If you play the 100 credits, you are elegible for the BONUS ROUND (which is the way you win the big money). In other words, it's $2 per spin.
Although I am not a big fan of progressives, the game offered more pay than you would normally expect for a $2 progressive. The bonus round has some excitement, as you are trying to collect as many "Red Hot Jackpot" symbols during the 8 free spins. Every time you get 3 symbols on one spin, you receive an additional 8 free spins.
If $2 a spin is close to your normal bet ... and you enjoy progressives, I thought this one was decent.
