Prompt Factory

Prompt Factory is a free arcade idle game about running a very small, very ambitious AI startup. Boxes of work ride a conveyor belt towards the ship gate, and your job is to ship each one at exactly the right moment. Every ship brings in cash, and that cash hires your first intern with a laptop. Soon you have prompt engineers, agent swarms, GPU racks and data centres, and eventually a datacentre on the Moon. Your team earns money every second, even when the game is closed.

How to play

• Tap the belt, or press Space, while a box is inside the glowing ship gate. Dead centre scores Perfect and pays double; the edges score Good.
• Every hit adds to your combo, which multiplies each ship up to six times. The belt speeds up as the combo grows.
• Tapping with nothing in the gate is a misfire: the combo resets and the gate jams for a moment. Letting a box slide past also breaks the combo, so mashing doesn't pay.
• Perfect ships fill the hype meter. When it is full, Launch day starts: for eight seconds every ship pays three times more.
• Let red bug boxes pass without shipping them. Ship gold star boxes for a big bonus.

Building the team

Below the belt is the factory floor. Each tile is a kind of hire with its price on it; tap the tile to hire. Choose how many at once with the bar above the tiles: one, ten, 25, 100, enough to reach the next milestone, or as many as you can afford. The small i on a tile opens its details, with the price of every amount side by side. Each copy costs 15% more than the last, and owning 25, 50, 100 and so on of one kind doubles its output each time. Upgrades appear as you grow, and you can buy every affordable one with a single button.

Events and away earnings

While you play, special boxes arrive on the belt. Ship a viral demo box for triple income for a minute, or an investor's briefcase for a few minutes of income at once. During an outage, four bugs come down the line: let every one of them through to collect a repair bonus. Close the tab and your team keeps earning for up to eight hours; a card shows the total when you come back.

Pivoting and tips

Once you have earned enough in one run, you can Pivot: the company starts again from zero with a new idea, and you collect Vision points that boost all future income by 25% each. Your combo records and shipped features carry over. To earn fastest, keep the combo alive: a steady rhythm of Perfects beats fast tapping every time, and Launch day at a high combo is where the biggest payouts come from. Spend at every check-in, since money sitting in the bank earns nothing.
