Highway Kings Pro is distributed on five reels and nine paylines, with coins ranging from 0.01 to 100 and up to 900 points. This is a huge improvement in the last game, with a maximum bet of 45. The sequel is also an upgrade of its predecessors in terms of graphics and bonus features, although the payment value is almost the same.
A new symbol shows a pair of red air pumps. This one pays five two, 25 three, 250 four and 5,000 five. The other six basic game symbols are bundled together. Therefore, we have two red dice and a 'King' baseball cap, which can be mixed and matched; bolts and jumpers can also be combined; and the steering wheel and tires, both of which conform to the "one" principle.
