Rubberband You are given a grid with nails sticking up. Each player X and Y is given k rubberbands. Player X "controls" a nail if one of X's rubberbands either touches that nail or that nail is within the area of one of X's rubberbands and the closest point of X's rubberband to that nail is closer than the closest point of any of Y's rubberbands to that nail. Otherwise Y controls that nail. There are certain constraints: a rubberband may not be placed such that any nail it touches has already been touched by another rubberband.
