I have heard about a 99.96% return game at Horseshoe Hammond. Which game is this, and is it still there? Does it allow you to earn 1 tier per $10?

Also I am looking at vpfree2, and it appears that the only 99%+ machines listed there which give 1 tier per $10 are deal/draw machines. I see that there are 9-6 Jacks or Better and 8-5 Bonus Deal-Draw machines supposedly giving 1 tier per credit. Is this true? Anyone have an idea on the actual return on such machines?
