The Panther Moon slot machine is at the higher end of the variance level, which means you have to wait for the free spin symbol to get a huge win.
It's not that you can't get some good victories in the base game, because the wild team has 2 times the multiplier, but the free spin game is really the place for this 15 payline game. But when you re-trigger... we played 45 free spins and used a 3x multiplier plus the wild multiplier at the top, we got a 443x bet at the end. And can achieve higher goals.
