Land three, four, five, or six scatter symbols anywhere on the reels to trigger 10, 15, 20, or 25 free drops, respectively. During this feature, treasure targets will land on every non-winning spin. Another symbol that is consistent in this feature is the bottomless chest. When this lands, it will rise up the reels to the highest possible size, leaving new symbols in its wake and expanding the reel set to the current maximum.
Three or more scatters landing during the free spins feature will trigger another 10 or more spins.
