Rules

Play

Decide what type of Polyomino game (square or hexagonal) you want to play.
Together, you and your opponent build the Polyomino taking turns to add a new adjacent cell until it's not possible to play any more.
Nim is usually played as misère game, but in Nim-o-Poly play is "Normal", in that the last player able to play is the winner, i.e. if you can't go then you've lost. The winner receives a number of points equal to the size of the polyomino finally formed.
Any new cell added during the game must
  • be connected to the current shape
  • not break the collinearity limit
  • meet any other restrictions of the variation being played
The Collinearity limit is the maximum number of cells that are allowed to be collinear on any line in the plane through the cell centres.
During the game all connected options are shown for selection, with the valid ones shaded green and the ones which break the collinearity limit shaded red. Selecting an invalid cell will show you why.
The shape, collinearity limit and variation can be set in the game options settings.

Variations

Territorial
In this variation you can only place a new cell next to your own existing cells, or the starting cell.
  • In Territorial 1 you can go next to the starting cell at any time.
  • In Territorial 2 you can only go next to the starting cell once (at the very start).
Choosing these variations will default the separate colours option as enabled.
