Furnace — Rules, Scoring and Strategy
A compact industrial engine builder played over four rounds, where losing an auction often earns the compensation needed to run a stronger factory.

Why it stands out
Furnace suits players who enjoy short engine-building Eurogames and tactical auctions. Its four rounds create a clear race to convert coal, iron and oil into money. Although the theme describes industrial capitalists, bidding is not only about winning cards: carefully placed losing bids collect valuable compensation. The base box supports 2–4 players, ages 14+, with a published 30–60 minute playtime.

Quick verdict and player fit
Furnace suits players who enjoy short engine-building Eurogames and tactical auctions. Its four rounds create a clear race to convert coal, iron and oil into money. Although the theme describes industrial capitalists, bidding is not only about winning cards: carefully placed losing bids collect valuable compensation. The base box supports 2–4 players, ages 14+, with a published 30–60 minute playtime.
Set up the four-round economy
Each player takes a starting company card with its indicated resources and four numbered Capital discs worth 1, 2, 3 and 4. Prepare the round tracker and supply of coal, iron, oil and money. Display a row of six to eight Company cards according to player count, basic side up. For a first game, leave out Capitalist personal-power cards and the locked production-chain variant.
Phase one: bid on companies
In player order, put one remaining Capital disc on a Company card. Repeat until everybody has placed all four discs. You cannot put two of your own discs on the same Company. A card also cannot hold two discs of the same value, even when those discs belong to different players. The numerical value is not a cash payment; it determines priority or compensation.
Resolve the auction left to right
Resolve each offered company from left to right. The player with the highest numbered disc acquires the card. All other players with lower discs on that company receive its printed compensation: typically resources multiplied by their disc value, or the displayed conversion ability used up to that many times. The winner does not take those compensation effects. A high bid can secure a company but deny you resources immediately.
Worked auction example
Suppose a company compensates losers with two coal per disc-value point. Red bids 4, Blue bids 2 and Yellow bids 1. Red wins the card, Blue collects four coal, and Yellow collects two coal. Blue might deliberately bid low if the rest of their factory urgently needs coal. If the offer instead shows a conversion effect, apply its stated limit and required input rather than simply taking cubes.
Phase two: operate your factory
After all offered cards are resolved, each player operates their own built companies. In the standard rules, you choose their order independently and resolve each company once during the production phase. Basic-side companies have a simpler production or processing operation. Upgrading flips an eligible company to its stronger side, typically providing additional actions. Move resources through the engine to generate more useful resources and cash.
Planning the conversion chain
Consider a factory that produces coal, another that converts coal into iron and a third that turns iron into money. Running them in that order can produce cash in the same round; doing the cash-conversion step first might waste the opportunity. A machine that does not seem profitable on its own can complete a chain. The limited four-round horizon means buying an engine component in round four provides fewer repeated activations than acquiring one earlier.
Optional Capitalist powers and production-chain variant
Capitalist cards grant asymmetric effects and may be added after players understand the basic game. The optional Production Chain rule restricts card order: once you insert an acquired company into a left-to-right sequence, you cannot rearrange the existing relative order. Its companies must operate from left to right. Do not mix this ordering restriction into the ordinary mode, where players can choose operating order.
Special two-player Agent
For two players, a dummy Agent uses a set of numbered discs to participate in bidding, governed by a die after the second human bid. The Agent can claim offered companies and remove them from play, but human losing bids still receive due compensation. This prevents two-player bidding from being identical to simply bidding without competition. Follow the rulebook’s placement search when a chosen card is not eligible.
End of game and exact tiebreaks
After production in the fourth round, total money earned. The richest player wins. Ties are broken first by who has more Company cards, then by who has more leftover resources. A pile of unused iron or coal is not directly cash at the end, so prioritize conversion on the final production round rather than hoarding input cubes without a scoring use.
Three strategic patterns
First, use discs 1–3 to target valuable compensation where another player likely places a larger bid. Second, value a Company not only by its printed money potential but by the cards already in your engine. Third, think one full round ahead: winning a mediocre company with bid 4 may be weaker than receiving multiplied inputs today and reserving bid 4 for a crucial processing card elsewhere.
Common rules mistakes
Do not place two discs of equal number on the same company. Do not collect compensation for the winning bid. Do not run a company more than once in production, and do not assume its upgraded side is active before it has been upgraded. Remember the two-player Agent and do not apply the optional locked-chain rule unless the table agrees to use that variant.
FAQ
Q: How many rounds are played? Four. Q: Do you pay the Capital disc’s number in money? No. Q: Why would I deliberately lose an auction? Compensation can supply crucial resources or conversions. Q: Can I reorder factories? Yes in standard play; no in the optional fixed-chain variant. Q: Does winning the final auction automatically win the game? No, money after the fourth production is what counts.
