Online Slot Review of Columbus Deluxe by Greentube

Columbus Deluxe Free Spins

The bonus option in Columbus Deluxe by Greentube is represented by a round of free spins. The initial duration of the round is 10 bonus spins regardless of the number of scatter symbols in the combination, however, you still have a chance to increase the number of spins. If 3 scatter symbols land during the bonus game you will receive an additional 10 spins.

During the bonus game the sail boats assume the function of additional Wild symbols that take on the value of ordinary pictures in case it helps to generate a combination. At the same time the function of the basic Wild symbol, the portrait of Columbus, remains the same.
