Developed by the Spanish studio Gaelco in 1990, the Xor World Prototype is an unreleased arcade puzzle game that never saw an official commercial launch. It remained in the testing phase, but the ROM has since been preserved and is fully playable through emulation. The core experience focuses on a falling-block format similar to classic tile-matching games, challenging you to carefully position and rotate pieces as they drop.
How to Play
Since this runs via arcade emulation, begin by pressing the 5 key to insert a coin, then press 1 to start. Use the Arrow Keys to direct the falling pieces left or right, and the Z or X keys to rotate them into the perfect fit before they lock into place.
