How to Play Xyzolog
Quick start
Roll toward the first flashing target and steer away from the green enemies. Save the explosion action for a situation where its cost in lives is worth clearing the surrounding danger.
Controls
Directional control: roll the ball. Explosion action: destroy nearby enemies at the cost of a life.
Xyzolog — About this game
Move the ball around the playfield and pass over the flashing red targets. Green spinning enemies make a direct route dangerous, so watch their approach before crossing an open area. The explosion action can destroy nearby enemies, but it costs a life and is therefore a deliberate sacrifice rather than an unlimited attack. Look for a path that reaches the remaining targets without needing that sacrifice. If you do explode, the position of several enemies around the ball determines how useful the blast will be.
