Lattice Lantern: Puzzle

Plan ahead — the obvious move is often a trap.

Lattice Lantern is a logic puzzle about light. Two beams, A and B, shine down from the two upper corners of a 5×5 grid. Rotate the mirrors so that each beam reaches the target marked with its own letter.

PREVIEW EVERY ROTATION BEFORE YOU COMMIT
Tap a mirror to see a dashed preview of where the beams would go. Tap it again, or press Rotate, to commit the turn. Every level has a limited number of rotations, so each turn counts.

WATCH FOR THE TRAPS
Walls stop a beam. A beam that ends on the decoy ring or on the other beam's target does not count. The move that looks right at first is often the one that leaves you stuck.

60 LEVELS + A 3-LEVEL TUTORIAL
Three short tutorial levels teach the preview, the two beams and the decoy. Then 60 levels in four chapters of 15 open one after another. Every level can be solved within its rotation budget. Replay any level you have solved.

AIM FOR OPTIMAL ◆
Solve a level in its optimal number of rotations to earn the Optimal ◆ mark. Each chapter shows how many levels you have solved and how many are marked ◆.

YOUR WAY TO PLAY
• Undo your last rotation (the rotation still counts)
• Continue where you left off
• Music, sound effects and vibration, each with its own switch
• English, Brazilian Portuguese and Spanish

Turn the mirrors. Send each beam to its own target.
