Honestly it sounds like the vp was better in the early 1600's, but I wouldn't want to live before the invention of paragraphs.
Nice hit nevertheless.
The pay table as shown is worth 122%, but needs to be more like 138 (for a 98% overall return) because the bet is 7 coins per line.
My math says average wheel spin should be about 335-340, and I seem to be in agreement with alpax who previously analyzed the game. Typical or median spin would be less than that because of the big jackpot potential. Is that consistent with your results? From my limited observations of other players, their spins have been reliably disappointing.
Strategy is gonna change because of the 35 flush and 25 straight. Inside straights move up in value. 3-card flushes show up near the bottom of the chart.
