Light Tracing

No special hardware. Just light, traced through the page.

An optional one-time graphics pack. The game traces sunlight, moonlight and lamplight through leaves, glass and water — for real shadows, soft bounced light and reflections — on a phone. Try it free first; the game checks your device before it lets you buy.

What it traces

The sun and the moon

Through leaves, glass and water. A pillar throws its shadow into a room; a pond picks up the moon.

Every lamp

A lamp lights the ground around it and the dark stays dark — thousands of lights, each one its own.

Bounce and reflection

Light comes off a wall and softens the wall opposite; water and gold reflect what stands over them.

Lamp posts along a pool at night with Light Tracing on: every lamp is reflected in the water.
Lamps at night, each one doubled in the water.

In motion

Recorded from the game: six places, each filmed twice on the same camera move — the plain look, then Light Tracing, joined by a wipe. The tracer itself never leaves the game.

Your phone decides

Three tiers — High, Ultra and Extreme. The game measures your device first, picks the tier it runs well and only offers the pack if it can. If it cannot, nothing is sold. You can change the tier any time in Settings › Graphics.
