The Highway Kings logo is shown in yellow in the top of the screen with large trucks on either side. Trucks are the main sign of wealth in this game, although you can earn good grades by finding matching combinations of other symbols. As always, all wins are paid from left to right, except for the dispersion, paying any fees. The theoretical regression rate is 97.06%.
Red trucks are wild and can replace all symbols to help you win prizes. In addition, wild doubles any victory, it helps to form, but not cumulative. In other words, the two wild symbols still multiply the victory by 2 instead of 4. The red truck symbol appears only on the center three reels.
