Tap a disc to turn it over with every disc above it. Settle the spire narrow to wide, every rune lit.
A spire out of order
A column of rune discs stands on its plinth, jumbled. Some runes face up and glow gold; others face down, dark slate. You never move one disc alone. Tap any disc and it turns over together with every disc stacked above it: the whole block flips, its order reverses and every rune in it changes face.

Settle every rune
A spire is settled when it reads narrowest on top to widest at the base, with every rune lit. A green pip marks each disc already resting in its final place, so you can see the spire take shape.

The trick is that a disc you settle at the bottom must have been on top, facing the right way, one turn earlier. Bring the widest disc up, turn it so it lands lit, then sink it with one long turn. Every turn has a cost: each spire has a par and a strict turn limit.

Five spires
Five spires grow from a first two-disc turn to a five-disc crown. Undo takes a turn back, even after you run out; Restart rebuilds the spire. Finish at par for a perfect settle, then tap Next. On the last spire, Again returns to the first.
