In the base game, helmets, beer, axes, gold nuggets, and maps are all more favourable symbols to hit than the obligatory 10, Jack, Queen, King, and Ace you find in the majority of slot games. The best-paying symbols are any of the cash symbols, which are all triggered in the main base game, but the gold nuggets and maps will set you on a path to a higher win. For the majority of symbols you will need a minimum of 3 appearances to trigger a winning combination. The only exception is the helmet that only requires 2 symbols.
