Kayles
Kayles is another example of a combinatorial game. On your turn, you may knock out any one pin or any two adjacent pins (on your first turn and only then, you may pass). The player to knock out the last pin wins. If you are using internet explorer and can't see the game, you might need to allow active content by clicking the info bar at the top of the screen.
To change the maximum number of pins or the probability that any given spot contains a pin, press the right mouse button and drag. Dragging vertically will change the max number of pins, dragging horizontally will change the probability of a pin occurring in any gien slot.
