This puzzle is part of a special round structure. See the Hall of Innovation solution for details.

This puzzle consists of a 3x3 grid of words and a 3x3 grid. Some cells in the bottom grid may contain a single coin showing “heads”. This suggests we need to take the “head” or first letter of the words in the corresponding cell.

We can extract these letters in reading order (left-to-right, top-to-bottom) for the answer.

This puzzle is affected by the following gizmos:
DialsRotates 1 row to the right, another left
ValvesFlips antonyms (label shape suggests which grid cells are flipped)
3x3 GridsShows or hides coins for extraction

Notably, when no keys are highlighted in the grid, this puzzle accepts the empty string as a valid solution.
