Age of Innovation

Power tokens cycle clockwise through your three Power Bowls: gaining power moves tokens from Bowl I→II, or from II→III if I is empty, and you can only spend tokens that are in Bowl III, which are then cycled back to Bowl I when spent (see p. 7).

Other Factions may gain power equal to the total Power values of their buildings adjacent to the newly built/ upgraded building, but they may choose whether to take that full amount or not; gaining power costs points according to the scale (1/2/3/4 power costs 0/1/2/3 points respectively), you cannot take a partial amount, and you can’t drop below 0 points (see p. 8).

No: Spades gained as a Science Bonus are awarded outside Phase II and therefore cannot be used to terraform-and-build until Phase II of the next round (see p. 12).

If you gain multiple Spades at once you must use them before building: any extra Spades may be applied to other reachable hexes (even up to 2 or 3 hexes), but you must complete the terraforming to your Native terrain on the primary hex first and you may only build one Workshop as part of that action (see p. 11–12).

An upgrade counts as the build of the new building and can trigger adjacency power for other Factions (they calculate power from their adjacent buildings and may opt to gain it), and you must exchange the old building by returning it to the rightmost empty space on its track on your Planning display before placing the new building (see p. 13 and p. 8).

Scholars you place on the Science display are generally not recovered, though you may return 1 Scholar to the supply to advance 1 Level in a Discipline as an alternative; note you have a limited pool of 7 Scholars, so placement is permanent unless you use that return option (see p. 15).
