Laser Station

Nine optics puzzles and a free-build sandbox, with a beam tracer that does the real physics — reflection, refraction and dispersion.

Light does what you tell it, if you ask properly.

Laser Station is a puzzle game about optics. Each level gives you a beam, a detector plate that will only accept one particular colour, and a few pieces of glass to arrange. Place them well and the right light lands where it should.

The physics is not faked. Mirrors reflect, prisms split white light into a spectrum, and glass bends every wavelength by a slightly different amount — so red leaves a prism at one angle and violet at another, and a plate asking for green will not settle for yellow. The beams you see are traced the same way the scene itself is lit.

Nine levels, each one checked by a solver before it shipped. The first needs a single mirror. The last has two lasers, two plates, and no straight line between them.

• Nine levels, from one mirror to a three-mirror maze • A sandbox with no goals, for building whatever you like • Real dispersion: red bends least, violet bends most • Pieces that refuse to overlap, so a solution is always a real arrangement • Play with touch, a mouse, or an Xbox, PlayStation or MFi controller • Game Center leaderboards and achievements • A single app for iPhone, iPad and Mac
