We’ve all heard the expression Big Kahuna, but how many of us actually know what it means? The most popular definition is a Hawaiian shaman. This slot has 5 reels and 9 unfixed paylines, which means wins can be formed both horizontally and diagonally. The bonus flourishes include scatter symbols, wilds and no less than two mini-games. In Big Kahuna, symbols include tribal masks, a shaman, a golden volcano, a monkey and an iguana.
