Highway Kings is a 5-volume 9 payline video slot machine game launched by Playtech Software. As the name implies, this game is highway-themed with trucks, wheels and spark plugs. The game can be played for free in many casinos, but free players will not be able to win the bulk of the cash prizes offered by this game. For real money players, they have the opportunity to play a jackpot, worth 10,000 gold coins.

The conventional symbols are red diesel, yellow diesel, green diesel, gas cylinders, air pumps, spark plugs, tweezers, pistons, wheels and steering wheels. The game also has a large red truck symbol that can replace all other symbols to form a winning combination. All payments for a combination done with wild symbols are automatically doubled.
