Scheduled for Essen 2007

A small 2-player abstract. The gameboard is a Q and on each space there are 2 stones. Stones have one of 4 colours and are neutral. Players take turns to remove stones from the board and place them in one line in front of them. Getting can only be done from either and of the Q, Placing can also be done to either and of the cue in front of the players.
The objective is to avoid stones with a colour not anotherwise in the cue.
