How does a Chain ×2 gate open?

One placement must cause two separate clears. The first clear can expose a lower color; if it joins enough matching layers, that same move clears again.

Tap an occupied stack to inspect its top and next color. This explains the layers without choosing a landing hex for you.

Open an ordered yellow-score route and a separate chain landing. Open the outer landing as the score grows. The two exits can unlock in either order; keep the middle usable for both. An outer landing opens at 30 score.
