New Game : PO-GO!

Figures 1,2 and 3 show the red player placing a stone with it's negative side up which causes all adjacent stones to be flipped to their negative polarities regardless of color.

Figure 4 shows that placing a stone with equal polarity does nothing.


PO-GO

2 player | 25 min

PO-GO stands for Polarity Go.

Hexhex5 board
Black and white Go stones each marked on one side.

The marked sides of the Go stones are the positive sides and the unmarked sides are negative.

Group – Two or more adjacent friendly stones of the same polarity.

Setup
Place the empty board between the players.
One player plays with the black stones the other the white stones.

Play
Turns alternate.

Black starts by placing (1) friendly stone with either side up onto any cell on the board. White then places (2) friendly stones with either side up onto any empty spaces on the board.

Players from this point on place (2) stones per turn.

Polarities
When a stone is dropped onto the board adjacent to other stones of equal polarity nothing happens. But when a stone is dropped adjacent to other stones of opposite polarity they are flipped over.

• So adjacent stones of equal polarity of either color you do nothing.
• Adjacent stones of opposite polarity of either color are flipped over.

The game ends when the board is full.

Object
The player with the largest group of friendly stones in either polarity at the end of the game wins.

If the groups of both players are the same size, look at the next largest set of groups etc. to determine a winner.
