Turn mirrors. Bend light. Light every crystal.
Beamlines
One light source on a dark grid. Tap a mirror and the beam turns; send it through a prism and it splits into three colors. Clear the level when every crystal glows in its own color.
■ How to play
· Tap a piece to rotate it. No dragging, no run button
· The beam is always flowing, so the path redraws the instant you turn something
· Fewer moves means more stars
■ Features
· 180 hand-built levels across 9 worlds — mirrors, walls, color filters, splitters, prisms, color mixing, mastery, twin lights, expert
· No tutorial text. The first level of each world teaches the new piece by letting you touch it
· A new daily puzzle every day, with streaks and world rankings
· The 180 main levels are ranked too - a board for every level, plus an overall standing
· Ads never interrupt a puzzle, and Unlock All removes them entirely
· No timers, no lives, no energy. Think as long as you like
· Hints are never sold for money. Watch a short ad for one — we ask first — and every level is solvable without it
■ How color works
· Red + green = yellow. Light adds up
· Color filters subtract from the beam passing through
· A prism splits white light three ways, and the direction you feed it decides where each color goes
■ What's free
· Worlds 1-3 (60 levels) and the daily puzzle are free
· Worlds 4-9 can be bought as single packs or opened together with Unlock All
· Unlock All also includes future world packs

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Two new worlds have opened.
- World 8 "Twin Lights" - two light sources. When they meet, their colors mix
- World 9 "Expert" - no new pieces, just much tighter puzzles
If you already own Unlock All, both worlds open automatically.
