But be careful, the big wins are waiting for five hammers, swords or three character symbols - this is between 20 and 150 times the stake. Yes don't forget, the wilds are the real all-rounders here, with the same value as the highest value symbol and the ability to substitute for any regular, non-expanding, paying symbol.
