The Highway Kings is a Playtech video slot machine with a truck theme, five reels and nine paylines. It can be paid for just two symbols spread anywhere on the active payline, and it can pay up to 100 coins, which is a maximum coin size of $10,000. The dollar ball feature requires players to choose five numbers. During each active rotation of Dollar Ball, the game randomizes five numbers and pays the player based on the number of matches. Players need to match all five numbers to win a jackpot worth at least $10,000.
Highway Kings features colourful hand-painted style. It works well. It's not particularly gorgeous, but it makes the game easy to read and play fast. The game has no music and sound effects, including real air horns and engine sounds, which are only played during the spinning action.
