In addition, any symbol that contains both Heidi and Hanna is an upgraded symbol and for each, you are awarded 3 additional spins! If you are lucky enough to land 20 or more bonus symbols, you are awarded 100 free spins. By landing 5 symbols, you are awarded 5 free spins and for each symbol up until the 19th, you are awarded 5 additional free spins for each one you land. To trigger the bonus, you need to land at least 5 bonus symbols on adjacent reels from left to right. You can play the game in one of two modes where the 'Prost' mode will make the Tappers active, where between 1 and 6 reels will be transformed wild.
