How to play

1. Read the +X/+Y/+Z dials: Each ingot shows how it shifts density, luster, and temper. Plan combinations that cancel out unwanted shifts — you need all three to reach 0 simultaneously.
2. Modular arithmetic wraps: If a property is at N−1 and you add +2, it wraps to 1, not N+1. Use this to your advantage when close to the target.
3. Right-click / long-press to remove: If you overshoot, remove ingots rather than resetting — it's faster and helps you learn which combinations work.
4. Match the "Optimal" count: Each level shows the optimal number of ingots. Fewer ingots = better, though only matching all three properties to 0 completes the level.
5. Metals escalate: Early levels use Copper & Tin (2 metals), mid-levels add Zinc (3), then Iron/Cobalt/Nickel/Manganese (4), and late levels use Gold/Platinum/Palladium/Iridium/Osmium (5 precious metals).
