Diya Light-Up

Six boards of clay lamps linked by threads, from a row of five on the doorstep to a rangoli flower of thirteen. Tapping a diya flips it and every diya linked to it, so dark ones light and lit ones go out. Light them all in as few taps as you can.

How to play

Tap a diya. It flips, and so does every diya linked to it by a thread: dark ones light, lit ones go out.
Light them all. Every board can be solved. Par is the fewest taps that does it.
Plan the set. The order of taps never matters, and a second tap on the same diya undoes the first.
Score. 150 per board at par, 15 less per extra tap, 40 less per hint, never below 20.

Quick tips

Order doesn't matter. Tapping A then B gives exactly the same result as B then A, so think about which diyas to tap, not when.
Never tap twice. A second tap on the same diya undoes the first. A shortest solution taps each diya at most once.
