Smokestack

A bare floor, $250, and a chimney with nothing above the roof yet. Put a Miner down, set a Seller beside it, and the works starts earning. Every dollar it earns raises the chimney a brick at a time, while the sky over the town turns from morning to night. Smelters turn ore into ingots; Assemblers turn ingots into widgets. Machines pass things to their neighbours, and belts carry them further, one load at a time and only the way they point. Find the bottleneck, buy the upgrade that breaks it, and grow the floor from 8 × 8 to 14 × 14. When the chimney is finished, found the next works: a new building on a fresh floor, where everything sells for twice as much and the chimney needs more. The old chimney stays on the skyline, so a long game becomes a whole town of them. Each works is scored by how fast you built it against a five-minute par, so there is always a quicker works to chase. Leave whenever you like. While you are away the works keeps running at half pace for up to eight hours, and its earnings are waiting when you come back. - Five machines, ten upgrades, and a new building and floor for every works - A score for speed, and a leaderboard to climb - Earnings while you are away, up to eight hours - A guide line that teaches the first minutes and names a stuck machine - Plays with touch, mouse, keyboard or gamepad
