Refrakt

Laser logic puzzles for iPhone. Place mirrors, splitters and prisms on a dark grid, bend a beam of light into every receiver, and watch white light shatter into red, green and blue — 400 free puzzles across eight chapters, no timers, and a one-time purchase to remove the ads.

The short version: no accounts and no server, and your progress never leaves your iPhone. Ads come from Google AdMob, with your consent where required.

Support

Questions, bug reports and stuck puzzles — plus answers to the common ones, from removing ads to how the third star is earned.
