Play Yaiba Online

Yaiba was a Game Boy release from 1990, developed by the studio Infinity and published by Asmik. It arrived during a period when many developers were experimenting with action-adventure formats on the handheld, creating compact worlds that fit in your pocket. The game presents a straightforward quest without extensive fanfare, typical of many titles from that era.

You control a young ninja navigating a series of side-scrolling stages. Your main goal is to rescue a kidnapped princess by fighting through enemy soldiers and mystical creatures. Signature mechanics include using a sword for close combat and a limited supply of shurikens for ranged attacks; you also jump between platforms and climb certain walls to access new areas. The pacing is deliberate, and the difficulty can be sharp, demanding precise jumps and quick reactions to enemy patterns. Moving through each stage feels like a careful, tense negotiation with the environment.
