Line up 4 side by side and that buddy freezes into a
flat ice block. Match the buddy again and the ice takes out
its whole row.
Line up 4 stacked up and the block stands upright.
That one takes out its whole column.
Line up 5 and Geo shows up. Swap him with any buddy
to clear every one of them.
Ice breaks the way it lies — and ice in
another block’s path goes off too.
