When the auction results are resolved, the players usually receive 2–3 new cards with the basic sides up and their bottom effects being not active just yet.
Then everyone manages their own industrial empire: the players resolve their cards one by one, in any order they wish (if they don’t play in a frenzy “Production Chains” Mode explained below), by activating all available effects.
It’s recommended to overlook each other’s actions in player order during the first few games, but after several game sessions, everyone will be able to resolve their facilities on their own.
There are the same 2 types of effects you’ve seen before: 1) gaining and 2) processing resources. However, here, the effect doesn’t get multiplied by your bid — it is limited by the card itself.
There is also a special effect available on each player’s starting card that allows upgrading facilities: flipping the cards and resolving their bottom effects.
