This game is basically a 3D tic-tac-toe, except that the rules have been changed to
keep the first player from winning all the time. Here you have to form two
rows that meet at a right angle (in the shape of an "L"). You play with blue marbles. Your
opponent -- the computer -- plays with red ones.
Click somewhere inside the grid to place a temporary (gray) marble. You can move
it around by dragging it with the mouse. To rotate the entire grid, in order to
get a better view, drag somewhere outside it. When you are satisfied with the
marble's position, double-click and it becomes permanent. Then it's the
computer's turn. And so on.
The "Skill" buttons control how hard the computer thinks. Higher button means
greater skill. Click the reset button (lower left) when you want to start over.
