Furnace

GAMEPLAY
The game is played over 4 rounds. Each round consists of 2 phases: Auction and Production.

AUCTION PHASE
Each player has 4 discs with values 1–4 to bid on the cards in the common row. The players take turns placing 1 of their discs on the cards until they don’t have any discs left.

Placement Rules
1. No discs of the same value on one card
2. No discs of the same color on one card

Then, the cards are resolved one by one in order from left to right. The highest bid receives the card. All other bids get compensated: the value of the disc multiplies the compensation.

PRODUCTION PHASE
Now, the players manage their own cards in any order they wish. They may gain resources, process them into other resources or money, and upgrade their cards for additional effects.

GAME END
When the 4th round is over, the player with the most money tokens wins.
