The Shark Slots
In The Shark, RTG provides probably one of the greatest penny slots ever created. That's right, there are no coin sizes to choose from in The Shark – you can only play with 1c coins. But it's still one of the top earners out there. Why? Because it has a progressive jackpot attached to it. There's a little display at the bottom of the screen that shows you what the total dollar value of the progressive is. And when you realise that you could win thousands and thousands of dollars for the investment of a single penny, suddenly this becomes a Must Play game.
