Extra Scoring System

[HLang]

Bingo knight. Computer generates a random bingo card for each player containing x squares that must be visited, and keeps track of all the knight moves made by each player across the tournament. First to move a knight to each square of the bingo card wins. Optional rule: Players do not see their card in order to avoid stupid finishes where an opponent with no pieces co-operates to win the prize; computer just keeps track of number of bingo squares found in a league table beside the games.

Battleships. Computer generates an 8x8 battleships grid for each player. The battleships game is played concurrently with the chess game. When a piece moves to a square, the battleships grid is automatically filled in. First player to win at battleships wins a prize. Battleships grid displayed on website alongside game.

Bullseye. "Keep out of the black and in the red, there's nothing in this game for two in a bed." 8 red squares chosen at random, each with a small prize behind, and displayed online alongside game. If a player moves a red square, they light it up for themself. But if another move is made on that square (by either player) the light goes out again. At the end of the game, the players win the prizes associated with the squares they have lit up.

Blockbusters. Players turn squares "their colour" by moving a piece to that square. First to complete a route across the board in any direction wins (diagonal links are OK). I think the squares would need to change colour each time someone landed on them to avoid blockages.

If any of these take off, I'll claim full credit. :-)
