How to play

Tap a stone: it and its four neighbours switch state (lit becomes out, and the other way round). Put out every flame, in three stages, before time runs out.

The story behind it

In the sagas, Brynhildr sleeps inside a wall of fire. The flame puzzle is made up for the game. Read the story in Brynhildr and Sigurd: the valkyrie in the ring of fire and the betrayal that ended on the pyre.
