A laser enters the maze from the left and you place mirror tiles to bounce it toward the exit on the right. Every mirror tile you place affects every subsequent reflection — one early mistake sends the beam into a dead end twenty bounces later. The maze grows to full-screen complexity with curved mirrors, one-way glass, and colour filters that change the laser's properties.

Coins fall from above and you position a bucket by tapping left or right to catch them. Gold coins score one point, silver half-point, but bronze coins drain a point if caught. The coins fall faster each ten seconds and eventually from multiple points simultaneously. A magnet power-up draws all gold coins toward your bucket for five glorious seconds.

Stars are being born across the cosmos in brilliant flashes and you tap each newborn star before it cools and goes dark. Blue dwarf stars are common, yellow stars rare, and a red supergiant blazes into existence once per run — worth a hundred points if caught before it collapses into a black hole five seconds later and pulls nearby stars away with it.
