During the bonus, the wild symbol on reel 2 becomes a 3x multiplier and the wild symbol on reel 4 becomes a 5x multiplier.
The bonus is triggered by landing 3, 4, or 5 bonus symbols on reels from left to right, starting with the leftmost reel for 10, 15, or 20 free games respectively. Wild symbols appear on reels 2 and 4 only. The standard game is a 'Reel Power' game which just means in order to win, you need to land the same symbols on adjacent reels from left to right: usually 3 but sometimes 2 depending on the symbol. Jackpot Catcher plays like Indian Dreaming which plays like Pompeii, with a Progressive feature added during the bonus.
While I don't necessarily advocate chasing progressives, I just couldn't help myself after Jackpot Catcher crested the $1500 mark, which I've never seen before.
