OpsDrive puts you in charge of a factory's production line, racing two rivals for the same customers. A hundred days, under an hour. Here's how it works. Leave the seed blank for a new game, or type the one your professor gave you, so the whole class plays the same game. Materials flow from left to right: raw materials, processing, finished goods. Yours is the green line. Everyone starts equal: five machines, $20,000, a third of the market. The bottom bar has the economics: demand, material cost, sale price. Your main lever is how much material to buy each day. Five machines finish five units a day. Advance a day and every line runs: machines pull from raw materials, finished goods go to customers, and sales show below. Buy more than your machines can process and the extra doesn't come out faster: it waits in front of the line, and your cycle time doubles. Capacity means machines, $10,000 each, and demand is growing. The bank lends in $5,000 steps against them, and charges interest daily. Your rivals plan too: you see their lines and their share, not their cash. Run short of finished goods and your customers go elsewhere. The Guide explains every number. Most final equity after a hundred days wins. Start with level one. Good luck, OpsDriver.
