Run a ready‑mix plant for 30 days. Each day:

• Set Base Price (USD/yd³). Higher price = margin ↑, demand ↓.
• Use Retarder (cuts rejects on hot/heavy) and Overtime (more turns; higher ops cost).
• Add capacity when capacity binds: Buy Truck (fleet) or Add Lane (+20% plant).
• Open the Store for tools: Profit Range Finder (find today’s profit‑maximizing price range), Event Radar (hot/heavy/cold/pour), Capacity Monitor (capacity + chart).
• Press Run Day to simulate and see results instantly.

Capacity: Delivered = min(demand, effective plant cap, fleet cap), shown in yd³/day.

Perishability: Hot or heavy days increase rejects; retarder reduces them.

Win: Finish day 30 with Cash ≥ 0 and Owner Value ≥ target.
