Arenaria: The Orderless Crown
A self-contained portrait-first Abelian sandpile puzzle. The player assigns four indistinguishable moon grains to seven illuminated wells, with repeated wells allowed. On release, every cell of value four or greater loses four grains and sends exactly one north, east, south, and west. Boundary grains enter four measured spill cups. The avalanche continues until all forty-nine cells are stable.
