During your turn, you may spend your civil actions to:
- pick cards from the card rows (if you have room in your hand)
- play cards to your tableau
- increase your population
- build/upgrade farms, mines, or urban buildings
- but building/upgrading military units uses your military actions
Yellow counters represent your population. They can be in one of three places:
- on your farms, mines, urban buildings (grey-backed cards, such as philosophy), or military units (representing workers)
- on your available population, which are available to place on your cards
- on your "yellow bank" -- when this is empty, you can no longer increase your available population
Blue counters represent food or resources. They can be in two places:
- on your farms or mines
- on your "blue bank" -- when this is empty, you can no longer produce
Building up your civilisation:
- Food lets you move workers from your yellow bank to your available worker pool.
- Resources let you move workers from your available worker pool to a card on your tableau.
- Science (light bulbs) lets you move cards from your hand to your tableau.
- When your population grows, you will need to produce more happiness or your workers will stop working.
- Producing culture will earn you victory points.
- Producing more military strength will protect you from raids or wars.
