Spread across 40 different levels, players must master their play-skills quickly as the ball increases in speed every 10 levels. No single play-through is the same, as hazards randomly spawn on top of blocks that still exist on the play field. Players will not be able to master the game through pattern memorization as they must constantly dodge fireballs launched at their paddle by randomly generated orange blocks, find their controls frozen when breaking a spawned black block, and avoid catching red power-downs that will siphon away their precious score. Players will luck out when breaking blue blocks that spawn additional bouncing balls to juggle or catching blue bonus icons that will begin a 15 second power-phase that will increase their scores by x2, x4, and x6.
