The bonus symbol, which appears on reels two, three, four, and six, can unlock the free spins bonus round.
You get a random number of free spins when three or four bonus symbols land on the reels.
The sixth reel remains unlocked during the free spins.
An extra reel with four soldier symbols appears at the top of the reels.
The soldiers show modifiers at random to award wild multipliers, extra free spins, and split symbols.
