Play X : Xekkusu Online

X: Xekkusu came out for the Game Boy in 1990, developed by Atelier Double and published by IGS. It was part of that wave of early handheld games that tried to do something a little different, a puzzle action hybrid that didn't rely on established franchises or familiar mechanics to find its audience.

You control a small, nimble character navigating single-screen puzzle rooms. Your main goal is to eliminate all enemies by triggering chain reactions, often by destroying a specific block or enemy to set off a cascade of explosions. The core mechanics involve careful positioning, timing your actions to avoid getting caught in your own blasts, and studying the layout to find the one sequence that clears the stage. The pacing is deliberate; you stop, look, and plan each move because a single mistake usually means starting over. It feels like patiently solving a volatile logic problem where you are also part of the equation.
