Circadians: First Light

All players assign dice in secret; only once everyone is finished do you remove Player Screens simultaneously to begin the Execute Phase, and you may not change assignments after reveal (pages 6, 8).

You may not alter rolled dice values during the Planning Phase; some alterations are allowed during Execute (the first Headquarters die may be flipped and the first Garage has a ±1 vehicle modifier, but those changes happen when actioning, not during Planning) (pages 7, 8).

If you cannot or choose not to pay the Algae cost for a Garage die (any but the left-most), that die and all dice to its right are immediately placed into your Cantina and for each die placed there you immediately gain 2 Water (page 8).

Dice placed on the Negotiation Board remain there for the rest of the game; the first unique die value placed earns an advancement reward, while reaching setback conditions (sum thresholds or duplicate values) forces you to take one available punishment when it triggers (pages 9–10).

To use the Depository you must place a die into the column matching its value and have the resources to trade for an Item in your hand; after buying, you also gain a row-based reward: top row lets you move your Harvester, middle grants a die for next round, and bottom draws 2 Item Cards (pages 10–11).

Harvesters may be moved off an edge using the edge arrows to immediately reappear on the opposite side of the Planet Board (wraparound), and harvesting (both Planet and Farm production) happens simultaneously in the Harvest Phase — Farms produce based on assigned die values (and the left Farm can boost other Farm dice) (pages 13, 15, 7).
