1. Make connections next to Geodes to hit them. Geodes take 3 hits to clear.

2. After 1 hit, a Geode's crystals are exposed. If a Square matching that color is made, the geode explodes and hits all the spaces around them!

3. Geodes have two types of goals. One to clear them off the board and another that only counts if they explode.
