The Jackpot Giant scatter symbol is desirable and triggers a giant bonus round, and your bonus can be tripled.
I played the 20-minute Jackpot Giant, was defeated by a small $25 out of $50, and then hit three Stacked Wilds, triggering the Free Spin feature, which would add me $100 or more. Finally, I came out before the end of the game and found that my ending balance was $96. I have a great time playing this slot!
