Zerdly

Tiny Foundry

A calm production-line game. Miners dig ore, smelters turn two ore into an ingot, presses turn two ingots into a part. Balance the line, sell what you need to, and deliver 10,000 parts.

Build a small production line — ore to ingots to parts — and deliver 10,000 parts.

Controls

  • Buy adds one machine of that kind; Pause stops a stage so its input can stockpile.
  • Sell 1, 10, 100 or all of any stock at fixed prices — the coins pay for the next machine.
  • Economy picks one of three presets and starts again; Start again restarts the current one.

The rules

  • Every second each stage works from the stock it had at the start of that second, so nothing passes through two stages at once.
  • Slow machines build up fractions of a unit rather than losing them, and stock never goes below zero.
  • Each extra machine of a kind costs 18% more than the last (rounded up). Prices: ore 1, ingot 3, part 8. Parts count as delivered when sold.

Scoring, saving and limits

Twelve milestones lead to the goal of 10,000 delivered parts. After that, play continues as clearly labelled endless play.

The foundry is saved on this device together with the moment it was last brought up to date, so time away counts once — up to 8 hours — and moving the clock backwards earns nothing.

No premium currency, paid boosts, adverts, prestige resets or real money. Very large numbers are capped at a trillion and shown as such. The three economy presets are Zerdly's.

Questions

Does it keep running when I close the page?
Yes, up to 8 hours. When you come back the same rules are applied to the time you were away.
Can a bad purchase leave me stuck?
No — you can always sell stock for coins, so you can recover and buy what you need next.
Why are my presses idle?
They are waiting for ingots. The progress panel names the current bottleneck.
