Games
Games and quizzes built to explore or learn something I've found interesting.
So far there is a range of puzzles and games. Typically I've been inspired by wanting to explore a particular puzzle or game for its own sake.

Puzzles I invented myself that were inspired by the Nikoli ones above.
Kirchhoff
Draw arrows that conserve the total sum between source and sink cells.
Sandfall
Grains fell on an abelian sandpile, avalanches settled, and some readings were lost to the wind. Mark which cells received a drop from what remains.
Territory
An inverse Voronoi map, paint every cell to its nearest hidden capital by taxicab distance. Settle the ties as no ones area.
Arbour
A spanning-tree puzzle. Link every cell into one tree from a root so each numbered cell sits at its true distance.
