The Cash Pump is a new online video slot from PlayNgo. Try Cash Pump with 12 reels with 4 different areas. Each play area has 5 fixed paylines, for a total of 20 fixed paylines. WILD symbols only appear on the center reel of each play area, substituting all symbols except SCATTER. The STACKED WILDS feature is triggered when any center reel is fully occupied by WILD symbols. All WILD symbols are then duplicated in the corresponding positions on all other play areas, multiplying any win by either x1, x2, x3 or x4. SCATTER symbols only appear on the center reel of each play area. 1 SCATTER symbol appearing on every play area (4 in total) will trigger 7 FREE SPINS.
