The Jackpot Express symbol, the Gold Truck, is wild and substitutes for any other symbol to complete a winning combination along any enabled payline.

Examples:

If a 1-Bar symbol and a 2-Bar symbol appear on an enabled payline with a Gold Truck symbol, this will complete an Any 3 Bar symbols combination.

Similarly, if two Gold Truck symbols and a 3-Bar symbol appear on an enabled payline, this will complete a three 3-Bar combination.
