Northcott's game (Nim variant)

The computer is your adversary and you play in turn. The last player is the winner.
You move the blue pegs and the computer the reds, on only one line at the same time.

The pegs go on any free box of the line where they are, towards the right-hand side or the left, but without jumping over the adversary peg. The blue ones remain on the left and the reds remain on their right. mais sans sauter par-dessus le pion adverse. Les bleus restent à gauche et les rouges restent à leur droite.

You start the game. The computer plays immediately after you.

Click on the empty box you chose to go, the blue peg of the line will move to this box. (But attention, it cannot pass beyond the position of the red peg)
