Play Oni - The Ninja Master Online

Oni: The Ninja Master came out in 1993 as an arcade release from Taito Corporation. It was part of that wave of side-scrolling action games that filled arcades in the early 90s, sitting alongside other titles that emphasized fast movement and combo-based combat. The game didn't redefine the genre, but it offered a solid, straightforward experience for players looking for something new to drop a few coins into.

You control a ninja character who moves through levels screen by screen, fighting off groups of enemies with a mix of sword attacks and special moves. The main goal is simply to reach the end of each stage while defeating everything in your path. Key mechanics include a double jump for evasion, screen-clearing special attacks that cost health, and the ability to pick up secondary weapons like shurikens. The pacing is quick, and the difficulty can spike sharply, especially when dealing with bosses or crowded enemy formations. Playing it feels like a constant test of reflexes and timing, where every mistake costs you.
