There are 11 symbols in Highways Kings, each representing different pay values. Icons include a steering wheel, a tyre, a bolt, a pair of dice, a gas pump, a petrol can, a jump lead and three differently coloured trucks: one green, one yellow and one red. Some of the symbols in Highway Kings grant pay-outs for combinations of three and above, but the better-paying icons award pay-outs for just two matching. The most generous symbol on the board – the red truck – even pays two credits for a single symbol on the reels.
On the whole, the pay-table is a generous one. The steering wheel and tyre icons are the game’s lowest-value, paying just 10 for four and 50 for five, but thereafter the sums increase quite a bit. At the top end of the scale are the three trucks. The green truck, for example, pays five for two, 20 for three, 150 for four and 1,000 for five. But even the yellow truck can’t compete with the red one, which pays two for one, 10 for two, 50 for three, 500 for four and a mammoth 10,000 for five.
