Checking the games paytable didn't reveal much about the maximum win either although I did find out that this BTG brand is actually a subsidiary of NextGen, which did give me confidence that this would probably be a quality product.
Many games with symbols of varying heights like this count taller symbols as stacks but thats not the case here, which can be pretty confusing at times. The paytable would really benefit from updating when you change the size of your bet too as all wins shown are calculated assuming you are playing the smallest possible bet size and so if your going to choose any other stake you'll either have to calculate the expected wins yourself or just scrap it and see what the game gives you! This seems a little lazy to me especially for NextGen.
I did enjoy playing Star Quest and it's a good looking game, but over 100,000 ways to win seems a bit over the top to me and it strikes me that this slot is only for players who like their games to be insanely high variance - and I really do mean insane, as this game seems brutal even to me, a huge fan of Playboy, Finer Reels of Life and Dead or Alive!
