Aurora Reservoir

Clear normal rows to gain charge. Spend 2 charge to open a three-drop aurora: completed rows stay frozen in place instead of collapsing. Release at least two frozen rows together to create one aurora show; make two shows to restore the reservoir. Release early if you need space, or wait for the automatic release after three drops. A blocked spawn releases available frozen rows before ending the run. Use the shape forecast to prepare: O is a square, I a bar, T a fork and L an elbow. Limit: 32 shapes; blocked placements spend nothing.

Tap a column, rotate, then Drop. Arrows aim. Retry repeats the seeded shapes; New reservoir varies them.
