Kid Niki: Radical Ninja is a classic action-platformer brought to the NES in 1986 by Irem and Data East. Players guide Niki, an unconventional ninja armed with a distinctive spinning sword, through a series of colorful, side-scrolling stages to rescue Princess Margo from the Stone Chopper. As a faithful arcade conversion, it delivers straightforward, fast-paced action where quick reflexes are essential.

How to play

Your goal is to reach the end of each stage and defeat its quirky boss using your spinning sword. The game is unforgiving, as a single hit from an enemy or projectile will cost you a life.

Tips

Your spinning sword extends further than it appears, allowing you to hit enemies safely from a distance, but the animation takes a fraction of a second to complete. Swing slightly before an enemy enters your range.
Each stage’s boss follows a strict, repeating attack pattern. Focus on dodging their projectiles first and look for the brief opening between their attacks to counter.
