Toichika 対符

Place one arrow per region so that all arrows pair off along a clear line of sight. Two arrows pair when they face one another along a row or column with no other arrow between them, and a pair may never join two regions that share an edge.

Three modes: Classic; Weave, where no two pairs' lines of sight may cross, so every sightline has to stay clear of the others; and Web, the inverse — every line of sight must cross that of another pair.
