openscad program for a cover-up tic-tac-toe game
- board - 3x3 grid of squares, same as tic-tac-toe
- cups - nesting pieces in 2 colors, each color having 2 each of 3 sizes. cups are played open side down, to cover smaller cups.
- stack - a set of one or more nested cups
a game for 2 players
the game starts with an empty board.
each player starts with 2 full stacks of the same color.
players take turns placing cups of their color, either from one of their stacks onto the board, or from one location on the board to another.
moving from one board location to another may uncover a cup, which is then in play.
cups can be placed on empty squares, or to cover a cup of a smaller size of either color.
a player wins when there is a full row of their color, either horizontally, vertically, or diagonally.
winning may happen either as a result of a player's own move, or their opponent's.
if a position is repeted 3 times, the game ends in a draw.
- this openscad program depends on the
slide_top_boxmodule - Gobblet (4x4) and Gobblet Gobblers (3x3) are board games designed by Thierry Denoual and published by Blue Orange Games that introduced the cover mechanic.
