## What is Hikari Fold?

Draw a small mirror in a dotted socket. Watch the light take a new path. Bring exactly the right color to every receiver and illuminate the room.

Hikari Fold is a collection of 36 light-routing puzzles across six chapters.

DRAW OR TAP
Draw a diagonal to place a mirror, or tap to cycle its orientation. A live preview follows your drawing, and the path updates when you lift your finger.

SIX WAYS TO THINK ABOUT LIGHT
Learn reflection, find routes around walls, combine colors at receivers, split beams into two paths, and filter white light into its components. The final chapter brings the mechanics together. Choose any room freely.

COLORS WITH CLEAR RULES
Red and green make yellow; red and blue make purple; green and blue make cyan. Beams combine at a receiver, not simply where they cross. Extra color components prevent a clear. R, G and B labels supplement the colors.

ROOM TO EXPERIMENT
No timer. Undo, erase, restart and unlimited hints let you try another idea. A hint first previews one correct placement; tap again to apply it.

YOUR OWN PACE
Adjust original music, sound effects, haptics and reduced motion. Audio respects silent mode.

Progress and mirror placements stay on your iPhone. No account, ads or in-app purchases. All rooms and hints work offline. No in-app cloud synchronization or transfer service.

Available in Japanese and English.
