Slide to turn up the heat — keep it steady
☕

Roast Master

Control the heat. Watch your bean transform. Listen for the crack.
This is what home roasting feels like.

🌡️

Use the Heat Slider

Move the slider to control how fast your bean heats up.
Steady rises produce better results than wild swings.

🔊

Listen for First Crack

Around 350°, your bean will audibly crack — that's your cue.
Let it develop for a bit longer, then press Cool the Beans.

🎯

Hit the Target

Each challenge has a target roast level — Light, Medium, Dark, and more.
Your score depends on accuracy, smoothness, and timing.
