Gridloc

A dice-and-board game on a six-by-six grid with columns 1 to 6 and rows A to F. One to five players and the computer take turns. Each turn the dice throw two different columns and two different rows, marking out a rectangle, and the player claims any square inside it, even one another player owns, which then becomes his. The first to own a square in every column and every row achieves GRIDLOC and wins; only the player who moves can win. The computer weighs each square, favouring columns and rows it lacks and blocking any player close to GRIDLOC. A score list beside the board shows the columns and rows each player covers, and a fanfare greets the winner.

Controls: Use either controller; players share it in turn. The stick moves the cursor and either button claims the square. On the title, push up and down to choose, left and right to change the number of players, and press a button to start.
