Lucky Nessie is a first and last keno game. When the player gets a hit with the 1st draw and the 20th draw the bonus is triggered. The bonus is free 10 games in the Fishy Photo Round where 6 bonus spots are added to the grid. All 5 of the yellow bonus spots trigger up to 15 extra draws each game.
Any extra draw that is a hit will count as the 20th draw making it easier to re-trigger the bonus and add additional free games. There is also a single red bonus spot for a 2x multiplier.
