On the Subject of Simon Stacks

Don’t worry, Simon! It’s not your tax.

Observe which of the hexes labeled A–H in the diagram flash. Use Table 1 to translate the combination of A–H into a combination of numbers 1–8, which in turn refer to rows in Table 2. Use the column corresponding to the color that flashed.

XOR each of the obtained patterns together. Press the background, then enter this resulting pattern by pressing the hexes that are filled, and press the background again to submit.

For each subsequent stage, perform the same operation with the newly added flashing hexes, but also XOR the pattern with the submission from the previous stage.
