One ball rolls through x1 to x4 multiplier gates until hundreds of balls flood the arena and smash a giant pane of glass.
Glass Rush asks one question: can the ball multiply fast enough to break the glass? A single ball drops into a round arena. The bottom half holds a set of nested U-shaped lanes, and at the bottom of each lane sits a multiplier gate marked x1, x2, x3 or x4.
Every time a ball rolls through a gate, that many new balls fly in through the entry gap in the wall. One ball becomes five, five become twenty, and within seconds a stream of hundreds is hammering the glass that fills the other half of the arena.
The glass breaks piece by piece, in ragged cracks, and the shards fall away. Behind it, spikes line the far wall and pop any ball that breaks through. When the last of the glass goes, it shatters in one wave and the round starts again.
