Oil Mania is a 25 line slot from NextGen with a bonus feature called UpWild. This is triggered by the appearance of a bonus Oil Tycoon symbol on reel 2,3, or 4 and it consists of 3 free spins with an Oil Well wild which expands up the reel he appeared on.
It’s a nice little bonus feature that seems to be triggered fairly often.
