Noughts and Crosses ( Tic-Tac-Toe ) with a twist. Each row of the vertical board can be slid one space left and right. If, by moving the row a token moves over an empty spot below then it will drop. If the token is moved over the edge of the "board" then it drops out altogether. This means that only tokens placed in the middle column are safe from ever being ejected from the board. The game has much more scope for strategy than normal Noughts and Crosses, either by (re)moving your opponents pieces or moving your own.
