Most idle games hand you a number that only ever goes up. Kiln gives you one real anagama firing — a single shared temperature, drawn live in cross-section — and dares you to hold every pot in its window without cooking it. You stoke wood to raise the heat, and the chamber cools on its own. Every ware on the shelves shares that one temperature. But each pot matures only while the heat sits inside its own cone band — the colored zone drawn right into the section. A teabowl ripens low; a tall tsubo needs real heat. Hold a ware in its band and its maturation bar fills; pull it fully matured and it pays reales. That is the whole tension. Push the temperature UP to reach the high cones, but the moment you overshoot a shallow-cone ware's band top, it bloats, slumps and greys out — ruined, lost. So firing is two-sided control: build heat to ripen the big pieces, hold it steady so you don't cook the little ones. You watch the glowing temperature line sweep through the bands live as your stokers work. Grow the firing: a bigger firebox raises the ceiling to reach higher cones, more stokers build heat faster, thicker walls hold it longer, more shelves fire more wares at once, and better clay widens every forgiving band. When a chamber is mastered, Open a New Chamber to bank master seals — a permanent multiplier on every ware's price — and fire a larger kiln. It runs while you're away: the fire keeps burning and the pots keep maturing up to ten hours, and pays you on return. • One shared temperature you raise, hold, and can overshoot • Cone bands drawn as live zones — wares glow in-band, grey out when ruined • Two-sided heat control: reach high cones without cooking shallow ones • Firebox, stokers, walls, shelves and clay to master the firing • Idle-friendly: the kiln fires offline and pays you on return • Open a New Chamber prestige banks permanent seals and a larger kiln • Fully offline, no account, nothing collected Stoke wisely. Pull them ripe.
