Spinning samurai players will be called into battle each time that samurai symbol appears on the first and fifth reels of the screen to activate the bonus game. Ultimately this will reward players with a series of free spins, during which all winnings have the potential to multiply. Before any of that happens, punters will have to fight 20 attacking ninja soldiers by throwing shuriken stars at them when they appear on screen. Each ninja you hit will potentially reward a free spin with up to 27 available or a multiplier up to the value of 8x. If you hit a special ninja then 3 more ninjas will be knocked out to award guaranteed free spins and / or multipliers. But be careful, because there are some ninjas who are fast enough to dodge your shurikens and finish the bonus game. If that happens, the accumulated free spins will be played with the collected multiplier applied to all winnings.
