When all 4 sections of a column or all 3 sections of a row on the Inspiration Grid have 1 or more Inspiration Cubes in them, the Resource Blocks at the end of that row or column are placed in the Unlocked Blocks Section of the HQ Board. When Resource Blocks are unlocked in this way, no Inspiration Cubes are spent.
Blocks in the Unlocked Blocks Section may be spent instead of pulling Blocks from the HQ Tower when paying for Actions and Directive Cards . Blocks spent in this way are also placed on top of the HQ Tower.
Inspiration Cubes may be spent in place of pulling Blocks from the HQ Tower at a ratio of 1-to-1. Leadership Inspiration may be spent in place of green Blocks, Technical Inspiration in place of orange Blocks and Scientific Inspiration spent in place of yellow Blocks. A.I. Inspiration can be spent in place of purple Blocks. See example.
