Cosmic Puzzles

About the game

Each level has a blue light source and a golden receiver. Between them sit transparent pieces that bend and redirect the beam.

Tap a piece to rotate it. Your first goal is to get the light from the source to the target. On most levels that is not enough: the path has to be shaped so the beam also passes through every crystal and lights it.

The 24 puzzles are split into three chapters, from simple tutorial levels to problems that require planning several moves ahead. Progress is stored in your browser, so you can leave and come back to the same place.

The game is fully translated: play it in Tajik, Russian or English. Your language carries over from this page.

Tips

Think backwards from the target: which side must the beam enter the receiver from?
Build the main path first, then reshape it to pick up the crystals.
Corner pieces often have only one correct orientation — start there.
There is no penalty for undoing. Experiment freely.
