This 5-reel 25-payline game is called Naughty Ninjas, precisely. The adult-style naughtiness pretty muchstops at the vaguely suggestive title character’s moniker of “Bubbles.” (In actuality, Naughty Bubbles looks a lot like Marvel Comics’ old supporting character Elektra.)
The storyline instead appears to feature some sort of alien invasion – at least three races, one of which is distinctly monoid reptilian, in a combined force – with only poker-playing ninjas left to defend the Earth. Or something like that. Otherwise, Naughty Ninjas is pretty standard stuff.
The SCATTER here is a “ninja star” which can magically appear in the third reel and make for some nice free spins and bonuses; a max $20,000 jackpot is promised. Deadly quick.
