3 × 3 Rec the Square

Two players, White and Black, alternately put dominos into a square. The player who cannot fit in a new domino loses, the other one wins.

You make your move by clicking into an empty field. Clicking the field again deletes this tentative move, clicking on a field adjacent to it confirms your move and completes the domino.

Creating Holes

A rather different game is played with the same rules of moves, but with different payoffs. Again, White and Black alternately move. Each player who can move has to move. The game ends when one player cannot move anymore. Then White gets for every empty corner field $1, and Black gets for every other empty field $1.
