The six machines listed in the vpFREE2 database need to be corrected as follows:
Full Pay Deuces Wild (this is correctely listed in the database)
Full Pay USA Poker (All American) quads pay 40 for 1, 100.72%
Full Pay Joker Wild (4000 for the Royal), 100.646%
Also the sign above these six machines quotes Jacks or Better at 100%. Unlike their counterparts at River Palms which pay 90 for one for a straight flush those at the Tropicana pay only 50 for 1 making the game 99.5%.
The other game on these six mchines is Double Double Bonus -- I'm not familiar with the game so I can't comment fairly on the credibility of being 100% or better.
One other thing: About half of these six slant tops have poor graphics.
