Spent a few minutes looking at the pay tables on the 12 machines in the bank (All have same offerings unless some subtle errors were made programming them!).
Pioneer's new slot manager (who replaced Doc) or upper management took their lead from Tropicana / River Palms -- "quarter players don't know what they are doing and will play anything and let's favor the $1 / $2 player"!!!!!!!!!
Didn't look at all of the games, but the following gives you an idea:
Bonus Poker ... quarter 6/5 ... fifty cent 7/5 ... forget $1 ... but $2 is full pay 8/5 (but still only 99.17%).
Jacks or better ... quater 7/5 ... fifty cent or $1 (again didn't want to be too obvious and write to much down) is 8/5 ... $2 is full pay 9/6.
Joker poker ... quarter and 50 cent are, as pointed out, two pair joker with 97% payback ... $1 and $2 are kings or better with royal at 4700, short pay 4x, etc ... 98% games.
DDB ... 8/5.
At this point a manager type that I've never seen before started hanging around so I didn't check any other games ... but you get the idea.
