The Orb is the Wild symbol, 5 of which pays 10,000x the line bet, and doubles all wins with it. Thank god it's not another true blue dumb Wild symbol, although it almost is. It also substitutes for other symbols except for the Scatter symbol. The Zodiac Wheel is the Scatter symbol, 5 of which pays a higher than usual 200x the total bet, which is good, and getting 3 or more of these Scatters trigger the Lucky Star Feature, with 7 free spins awarded initially, followed by a spin on the zodiac wheel for either a Bonus game or more free spins with a multiplier. The other symbols in the game pay from 1500x the line bet down to 100x the line bet for 5 of each kind. Can be considered a good paytable although the other symbols do have slightly lower values.
After getting that initial 7 free spins after triggering the Lucky Star feature, pick one zodiac sign, spin the wheel and see where the wheel stops. If the picked sign is won, a choice of either a Bonus or a Free Spins game is awarded. The number of free spins and multiplier would be shown, so pick which you would prefer. In the Bonus game, pick 5 Constellations to win cash prizes. Pick the Free Spins game and the free spins amount and multiplier shown would be added to the initial 7 free spins.
For me, I have picked one of each game on separate occasions, to see how each one would play and pay. Both games could pay well and both could pay quite poorly too. The lowest win that I've got was 16x my bet amount, the highest was 67x. Not a lot and not too high a win, but the best have still not been achieved yet, that's for sure. The good paytable do provide for much bigger wins that what I had gotten, just haven't been lucky enough so far. But then again, I have very seldom been lucky on any of Microgaming games. Strange but true.
